Compared to European political and security circumstance, minimum deterrence is less an illusion in other regions where weapon free zones already exist. It will continue to be relevant to the security of other regions. Strategic arms limitation should be pursued vigorously in a constructive and pragmatic manner, bearing in mind the need to readjust to new global challenges. The Comprehensive Test Ban Treaty is the linchpin on which the Non-proliferation Treaty rests

Full Text Available The main objective of this paper is to examine the regional maritime security challenges facing Indonesia. As it is known that entering to the 21st century has come a new term in regional architecture in the Asia-Pacific region, namely the Indo-Pacific region. This region consists of the Indian Ocean and Pacific. Both of these areas became more interconnected than in the previous period. These two regions became a single, significant system in the global order. Key players in the Indo-Pacific region are China, India and the United States. Of course, their actions have created new challenges in maritime security. These challenges include maritime disputes, pirates, and maritime power competition. The dispute in the South China Sea has spawned a security problem in the Asia Pacific region that Indonesia must face in the future.

One of the major problems is that nuclear industry is in very early stage in dealing with cyber security issues. It is because that cyber security has received less attention compared to other safety problems. In addition, late adoption of digital I and C systems has resulted in lower level of cyber security advancements in nuclear industry than ones in other industries. For the cyber security of NPP I and C systems, many regulatory documents, guides and standards were already published. These documents include cyber security plans, methods for cyber security assessments and comprehensive set of security controls. However, methods which can help assess how much security is improved if a specific security control is applied are not included in these documents. Hence, NPP I and C system designers may encounter difficulties when trying to apply security controls with limited structure and cost. In order to provide useful information about cyber security issues including cyber security enhancements, this paper suggests a framework to evaluate how much cyber security is improved when a specific cyber security enhancement is applied in NPPs. In order to provide useful information about cyber security issues including cyber security enhancements, this paper suggests a framework to evaluate how much cyber security is improved when a specific cyber security enhancement is applied in NPPs.

The role of information technologies in providing technological security for energy enterprises is a component of the economic security for the northern Arctic region in general. Applying instruments and methods of information protection modelling of the energy enterprises' business process in the northern Arctic region (such as Arkhenergo and Komienergo), the authors analysed and identified most frequent risks of information security. With the analytic hierarchy process based on weighting factor estimations, information risks of energy enterprises' technological processes were ranked. The economic estimation of the information security within an energy enterprise considers weighting factor-adjusted variables (risks). Investments in information security systems of energy enterprises in the northern Arctic region are related to necessary security elements installation; current operating expenses on business process protection systems become materialized economic damage.

A Catalyst for Change: Drought and Food Security in the Near East Region (Invited)

Knutson, C. L.

2010-12-01

In the Near East, drought at the turn of the 21st century was reported to be the worst in 50 years, affecting millions of people across the region. The drought caused a wide range of effects, including widespread crop failures and livestock losses, increased drinking water shortages and disease stress, additional debt, and forced mass migrations to urban areas and other countries, all of which affected food security. As devastating as the drought was for people and the environment, the event created a “policy window” - a time during which the public’s and policy makers’ attention was directed toward a particular issue, creating an advantageous political environment for addressing the problem. In this case, the drought revealed the need for enhanced mitigation and drought relief coordination. It has served as the impetus for several countries and international organizations to work together to foster new policies and training activities to reduce drought risk and enhance food security in the region.

Evaluating energy security in the Asia-Pacific region: A novel methodological approach

International Nuclear Information System (INIS)

Vivoda, Vlado

2010-01-01

This paper establishes an 'energy security assessment instrument' based on a new and expanded conceptualisation of energy security. The instrument is a systematic interrogative tool for evaluating energy security of individual states or regions. It consists of eleven broad energy security dimensions associated with the current global energy system. These energy security dimensions take into account numerous quantitative and qualitative attributes of each country's energy security and policy, and include both traditional energy security concerns and many new factors, such as environmental, socio-cultural and technological. Another dimension, largely absent from previous analyses, is the existence of, and the issues addressed in, energy security policy in each country. This instrument serves as an assessment system with which to evaluate energy security in the Asia-Pacific region. The existing studies on energy security in the Asia-Pacific region suffer from serious limitations. No study to date examines regional energy security policies by adopting a more comprehensive energy security definition as a starting point. Most studies also focus on a single country or issue. Even if they examine energy security in major regional economies, they lack critical comparative analysis. The instrument is valuable as it may be utilised to draw a comprehensive map of regional energy security situation, which can also include comparative analysis of energy security characteristics across the Asia-Pacific region. Ultimately, it may be utilised to set up a framework for improved regional energy cooperation with the aim of providing regional leaders with a blueprint for improving regional energy security and policy.

Security-Enhanced Push Button Configuration for Home Smart Control.

Science.gov (United States)

Han, Junghee; Park, Taejoon

2017-06-08

With the emergence of smart and converged home services, the need for the secure and easy interplay of various devices has been increased. Push Button Configuration (PBC) is one of the technologies proposed for easy set-up of a secure session between IT and consumer devices. Although the Wi-Fi Direct specification explicitly states that all devices must support the PBC method, its applicability is very limited. This is because the security vulnerability of PBC can be maliciously exploited so that attackers can make illegitimate sessions with consumer devices. To address this problem, this paper proposes a novel Security-enhanced PBC (SePBC) scheme with which we can uncover suspicious or malicious devices. The proposed mechanism has several unique features. First, we develop a secure handshake distance measurement protocol by preventing an adversary sitting outside the region from maliciously manipulating its distance to be fake. Second, it is compatible with the original Wi-Fi PBC without introducing a brand-new methodology. Finally, SePBC uses lightweight operations without CPU-intensive cryptography computation and employs inexpensive H/W. Moreover, it needs to incur little overhead when there is no attack. This paper also designs and implements the proposed SePBC in the real world. Our experimental results and analysis show that the proposed SePBC scheme effectively defeats attacks on PBC while minimizing the modification of the original PBC equipment.

Kawakubo, Y.; Tomikawa, H.

2015-01-01

Nuclear transparency is defined as ''a cooperative process of providing information to all interested parties so that they can independently assess the safety, security, and legitimate management of nuclear materials'' by Sandia National Laboratories (SNL). Since the Asia- Pacific region has a broad spectrum of nuclear development underway and planned in the future, nuclear transparency is recognized as essential to provide additional assurance and enhance confidence building in this area. It is expected that elevated nuclear transparency should also supplement International Atomic Energy Agency (IAEA) safeguards. With this recognition, JAEA has committed various studies and activities for enhancing regional nuclear transparency mainly with U.S. Department of Energy (DOE) and its national laboratories. The efforts include concept study, development of secure data transmission technologies at the Experimental Fast Reactor ''Joyo'' for the use of regional nuclear transparency, and support for Council for Security and Cooperation in Asia Pacific (CSCAP) to develop internet-based transparency tools. JAEA also organized several workshops to discuss with stakeholder organizations to build acceptance for transparency tools and activities. Based on the past studies, JAEA, jointly with SNL, Korea Institute of Nuclear Nonproliferation and Control (KINAC) and Korea Atomic Energy Research Institute (KAERI), initiated a new phase of study in 2011 to design and establish an Information Sharing Framework (ISF) which was defined as ''a communication platform on which nuclear nonproliferation experts can provide and/or receive relevant information in a practical and sustainable manner''. During the period of two-year study, partner organizations identified essential elements to establish ISF and developed the requirements. Currently, JAEA and KINAC are planning to implement demonstration of ISF under Asia Pacific

Future regional nuclear fuel cycle cooperation in East Asia: Energy security costs and benefits

International Nuclear Information System (INIS)

Hippel, David von; Hayes, Peter; Kang, Jungmin; Katsuta, Tadahiro

2011-01-01

Economic growth in East Asia has rapidly increased regional energy, and especially, electricity needs. Many of the countries of East Asia have sought or are seeking to diversify their energy sources and bolster their energy supply and/or environmental security by developing nuclear power. Rapid development of nuclear power in East Asia brings with it concerns regarding nuclear weapons proliferation associated with uranium enrichment and spent nuclear fuel management. This article summarizes the development and analysis of four different scenarios of nuclear fuel cycle management in East Asia, including a scenario where each major nuclear power user develops uranium enrichment and reprocessing of spent fuel individually, scenarios featuring cooperation in the full fuel cycle, and a scenario where reprocessing is avoided in favor of dry cask storage of spent fuel. The material inputs and outputs and costs of key fuel cycle elements under each scenario are summarized. - Highlights: → We evaluate four scenarios of regional nuclear fuel cycle cooperation in East Asia and the Pacific. → The scenarios cover fuel supply, enrichment, transport, reprocessing, and waste management. → We evaluate nuclear material flows, energy use, costs, and qualitative energy security impacts. → Regional cooperation on nuclear fuel cycle issues can help to enhance energy security. → A regional scenario in which reprocessing is rapidly phased out shows security and cost advantages.

Currently, the most developed countries are occurring a transition from the industrial society to the information society. The industry 4.0 as the continuous communication at all levels and characterizes the production processes, in which technologies and devices interact automatically in the value-added chain. Under these new conditions, the former types of organizational structures of economic entities are not sufficiently effective. Therefore, there is a need to create new, modern types of organizational structures. One of these types is network structures. Currently, they are becoming characteristic features of the new economy. Regional economic security depends on internal and external threats, which lead to unstable situations. Regional crisis situations are influenced by both macroeconomic crisis processes and local features of economic and social development, as well as the resource potential, geographical location, national and other peculiarities. The article defines the specific characteristics of the regions of the Ural Federal District, as well as the current situation of the regional economy and threats to the region. The authors have evaluated the economic security of complimentary production networks at the regional level. This evaluation has revealed the interconnection between complimentary production networks and the construction industry in the national economy. We have defined the economic security of complimentary production networks and specified the concept of complimentary production networks. The research findings may be applied by organizations as a new perspective of industry using network forms related to economic security

Cooperative monitoring systems can play an important part in promoting the implementation of regional cooperative security agreements. These agreements advance the national security interests of the United States in a post Cold War environment. Regional issues as widely varying as nuclear nonproliferation, trade and environmental pollution can be the source of tensions which may escalate to armed conflict which could have global implications. The Office of National Security Policy Analysis at the US Department of Energy (DOE) has an interest in seeking ways to promote regional cooperation that can reduce the threats posed by regional conflict. DOE technologies and technical expertise can contribute to developing solutions to a wide variety of these international problems. Much of this DOE expertise has been developed in support of the US nuclear weapons and arms control missions. It is now being made available to other agencies and foreign governments in their search for regional security and cooperation. This report presents two examples of interest to DOE in which monitoring technologies could be employed to promote cooperation through experimentation. The two scenarios include nuclear transparency in Northeast Asia and environmental restoration in the Black Sea. Both offer the potential for the use of technology to promote regional cooperation. The issues associated with both of these monitoring applications are presented along with examples of appropriate monitoring technologies, potential experiments and potential DOE contributions to the scenarios.

Electronic consent becomes increasingly popular in the healthcare sector given the many benefits it provides. However, security concerns, e.g., how to verify the identity of a person who is remotely accessing the electronic consent system in a secure and user-friendly manner, also arise along with the popularity of electronic consent. Unfortunately, existing electronic consent systems do not pay sufficient attention to those issues. They mainly rely on conventional password based authentication to verify the identity of an electronic consent user, which is far from being sufficient given that identity theft threat is real and significant in reality. In this paper, we present a security enhanced electronic consent model called USign. USign enhances the identity protection and authentication for electronic consent systems by leveraging handwritten signatures everyone is familiar with and mobile computing technologies that are becoming ubiquitous. We developed a prototype of USign and conducted preliminary evaluation on accuracy and usability of signature verification. Our experimental results show the feasibility of the proposed model.

The threat of nuclear terrorism has become a global concern. Many countries continue to make efforts to strengthen nuclear security by enhancing systems of nuclear material protection, control, and accounting (MPC and A). Though MPC and A systems can significantly upgrade nuclear security, they do not eliminate the 'human factor.' Gen. Eugene Habiger, a former 'Assistant Secretary for Safeguards and Security' at the U.S. Department of Energy's (DOE) nuclear-weapons complex and a former commander of U.S. strategic nuclear forces, has observed that 'good security is 20% equipment and 80% people.' Although eliminating the 'human factor' is not possible, accounting for and mitigating the risk of the insider threat is an essential element in establishing an effective nuclear security culture. This paper will consider the organizational role in mitigating the risk associated with the malicious insider through monitoring and enhancing human reliability and motivation as well as enhancing the nuclear security culture.

Full Text Available In the article, the relevant problem of increasing the regional budget revenues is investigated. The subject matter of the research is the securities market as a mechanism for the redistribution of financial resources. The purpose of the research is justification of the effective scheme feasible in the current environment of the interaction of the securities market and the regional budget. In the study of the above-mentioned subject, the hypothesis of a close relationship between state and non-state finance system was taken as a basis. The theoretical principle of the research supports the theory of the stock market; to achieve the purpose, the institutionally-functional approach to the study of state finances is applied. As the result of the research, possible common grounds of the securities market and the regional financial system are identified; the reserve of improving efficiency of the securities market in the Western Siberia regions are revealed; the model reflecting the dependence of tax revenues from the pace of regional economic development is constructed; promising areas for development of the securities market for the benefit of the regional economy and regional financial system are formulated; the possible effect from the development of regional securities market on regional budget revenues is estimated. The results mentioned above are recommended to be apllied when developing regional financial policies and programmes of region socio-economic development. A long-term stimulation of the growth in incomes of regional budgets is a very complex process, but with the proper elaboration of organizational issues, the implementation of the proposed scheme for interaction of the securities market and the regional financial system is capable to provide a steady increase in tax revenue in the short term and alleviate the problem of financing costs of the regional budget.

The study attempted to find out changes in households food security and daily activities in the face of climate change for the last twenty years. The study started with the 150 household surveys along with participatory rural appraisal to understand the climate change perception of local people and its impact on dimensions of food security. Households expressed different levels of perception in terms of climate change on food security. The result shows that most of the mountainous households experienced increased temperature, less rainfall in winter, an increasing number of natural disasters and the emergence of insects for the last twenty years. They perceived the role of climate change in decreased crop production, decreased dairy products and increased household work. The situation of food security is likely to be more vulnerable to climate change in the future. It was also observed that households have been using different autonomous adaptation measures, such as high yielding crop varieties, enhanced irrigation systems and fertilizers, to cope with the changing climate. Finally, the study recommended policy instruments to enhance food security in the mountainous region amidst changing climate.

Ever since the weapons of mass destruction have become an international currency of power, the efforts for their control and elimination have also developed simultaneously, as an important stream in international politics. Countries all over the globe have strived to evolve various devices to ensure security against these weapons at international, regional as well as national levels. One such regional effort for nuclear arms control is the creation of nuclear-free zone. The nuclear free zones present a potentially effective option to supplement the global nuclear disarmament regime. This is an endeavour towards crisis management, reducing the threat perception, common security and confidence building. In addition, they help in creating a regional security order by developing a code of conduct which binds external actors as well as the regional countries. They are meant to reduce if not eliminate the likelihood of a region getting involved into the war of mass destruction. It is in this context the cases of Southeast Asia and the South Pacific nuclear-free zones have been discussed in this book

A case for avoiding security-enhanced HTTP tools to improve security for Web-based applications

Energy Technology Data Exchange (ETDEWEB)

Wood, B.

1996-03-01

This paper describes some of the general weaknesses of the current popular Hypertext Transmission Protocol (HTTP) security standards and products in an effort to show that these standards are not appealing for many applications. The author will then show how one can treat HTTP browsers and servers as untrusted elements in the network so that one can rely on other mechanisms to achieve better overall security than can be attained through today`s security-enhanced HTTP tools.

Nordby, Johannes Riber; Jacobsen, Katja

2013-01-01

For the past decade, peace and security in East Africa have gained increasing focus internationally. The region has experienced armed conflicts, civil wars, rebellion, drought and famine. Yet, at the same time, there is an emerging ambition among a number of African states to handle security issues...... on the continent independently. Such ambitions have fostered a variety of military capacity building programmes supported by external donors. The present report explores how up until now Denmark has sought to contribute to strengthening political and military security in East Africa. This has mainly been done...... through capacity building projects anchored in different regional security institutions. The report illuminates some of the risks that such capacity building projects might confront. Furthermore the report points out some of the challenges that exist in the cooperation between the Ministry of Foreign...

Security assurances and regional stability

International Nuclear Information System (INIS)

Sanders, B.

1995-01-01

This paper discusses whether and how security assurances affect political stability in geographic regions. Before embarking on what is necessarily a limited analysis of a complex subject, I point out that the subject is by no means new. For centuries, vast areas of the world have been affected by forces used against them by more powerful States, which at one time or another incorporated large parts of them into overseas colonies or contiguous empires. The new factors are the emancipation of those areas into independent regions, made up of States that play their own parts in international affairs, and the possession by a handful of Powers, outside or on the edge of those regions, of a specific form of superior force: nuclear weapons.

Highlights: • The most influential factors affecting China’s energy security are identified. • Fuzzy AHP is used to quantify the importance of influential factors. • Strategic measures for enhancing China’s energy security are prioritized. • Fuzzy AHP is used to determine the priorities of the strategic measures. - Abstract: This study investigates the most influential factors affecting China’s energy security. It also identifies the most effective strategic measures for enhancing it. Fuzzy AHP has been used to determine weights for ranking the importance of Chinese energy security factors, and it has also been used to determine the priorities of the strategic measures with respect to enhancing those same factors. The study argues that a low proportion of renewable energy penetration is the most severe factor threatening China’s energy security, and that conducting research and development on energy technologies and improving energy efficiency is the most salient, positive, and necessary strategic measure

Minimum deterrence and regional security. Section 1. Europe

International Nuclear Information System (INIS)

Gnesotto, N.

1993-01-01

The impact of regional security in Europe on the minimum nuclear deterrence is analyzed. There are four factors that enable definition of specific features of European security. Europe is the only theatre in which four of the five nuclear Powers coexist, where three states, Ukraine, Belarus and Kazakhstan, represent a new type of proliferation. It is therefore the strategic region with the heaviest concentration of nuclear weapons in the world. Finally it is a theatre in which regional wars are again a possibility. In other words, the end of cold war meant return of real wars in Europe on one hand, and on the other, a combination of absolutely massive and essential nuclear capability and over-increasing economic, political and diplomatic instability. In spite of these circumstances nuclear deterrence in Europe is inevitable and desirable

The Arab Uprisings and Euro-Mediterranean Security: The Regional Security Agenda of the European Union

Directory of Open Access Journals (Sweden)

Schima Viktoria Labitsch

2014-12-01

Full Text Available The 2010 Arab uprisings led to profound changes in the political landscape of the Southern Mediterranean, and came at a time of staggering Euro-Mediterranean relations. With prevailing turmoil and violence in Europe’s closest proximity, the Euromed relationship – heavily dominated by security objectives and concerns in the past – is facing new social, political and economic challenges. This work analyses what challenges have made it onto the security agenda of the European Union in response to the uprisings in Tunisia, Libya and Egypt between December 2010 and 2013. It does so by analysing the discourse of three institutions: the European Commission, the European Council and the Council of Ministers. Accordingly, it argues that security in the Euro-Mediterranean context may be analysed in the framework of the wider constructivist Copenhagen school of security studies, treating threats as politically constructed in the process of securitization. It emphasizes the different degrees of institutional involvement in framing the regional security agenda, and the vast application of security logic to migration and mobility as well as its absence in areas of biological and chemical weapons, extremism and weapons of mass destruction. This work’s final argument is that whilst the overall level of securitization throughout the three years remains low and partially inconsistent with the security priorities before 2010, the EU exhibited a particularly strong regional focus on Libya as well as a thematic one on migration and external borders.

State regulation as a tool for improving the economic security of the regions

Full Text Available Providing economic security for the development of regions, increasing their competitiveness, risk-free and sustainable activities are the main tasks of the regional program of social and economic development, which occupies a special place in the system of instruments for public management of these processes. The program of social and economic development is a unique strategy of the region aimed at security and optimization of the spatial structure and relations between the center and the regions in order to ensure economic security and growth by maximizing the effective use of existing internal and external factors. The institutional influence of the state in order to improve the economic security of regions and enterprises occurs palliatively when the business of the region is supported in direct – subsidies, and more often indirectly – compliance with the laws and regulations of the Russian Federation and the region, on the principles of institutional and market synergies. Adaptation of enterprises in the region to the market is difficult, when specific socio-organizational, economic, technical and technological, scientific, information activities in their interrelations function in the field of Russian laws. The search for ways to improve the economic security of the Russian Federation, regions and enterprises takes place in the context of global integration through the improvement of the mechanism of state regulation. An important task of the current stage of economic security of the country and regions is the construction of a system of its institutional organization that would be able to balance the levers of government with the opportunities of private enterprises, provide a quality level of providing the business with protection from terrorism, predation, financial risks, legal competition etc.

Approaches to regional security and arms control in North-East Asia: Tasks ahead

International Nuclear Information System (INIS)

Lee Seo-Hang

1992-01-01

In order to pave the way towards regional security and arms control in North-East Asia, one of the outstanding issues left over from the cold war, that is, the question of a divided Korea-must be solved first. In settling the Korean problem, the importance of the bilateral negotiation between the parties in direct conflict can never be overemphasized. Over the past few years, fortunately, there has been an accumulation of developments that would have a positive effect on the improvement of inter-Korean relations and peaceful unification of the peninsula. In this sense, the first challenge for the two Koreas is to fulfil the pledges that they committed in the agreements. Concluding agreements is only a first step. They must be implemented fully both in letter and in spirit. Only upon the sincere and complete translation of the agreements into action can the two Koreas establish a solid peace system and move towards unification. This fulfilment will eventually contribute to security and stability in North-East Asia. To emphasize the importance of bilateral negotiation between the two Koreas is not necessarily to exclude the role of external Powers. The four major Powers in North-East Asia-China, Japan, Russia and the United States - could support the South-North dialogue, help ease tensions, facilitate discussion of common security concerns and possibly guarantee the outcomes negotiated between the two Koreas. By fostering bilateral negotiation between the parties to the conflict, they could contribute to enhancing security, confidence and disarmament in the region. At this moment, the most urgent task in the Korean peninsula relates to the problem of Pyongyang's nuclear weapons programme. To solve the nuclear problem, a significant progress on mutual reciprocal inspections must be made immediately in accordance with the wordings of the Declaration. Mutual inspection will test whether Pyongyang intends to go towards nuclear weapons, or away from them and towards

Full Text Available The investigation of threats negatively affecting the state and the development of human resources as well as the varieties of security threats is of particular importance in the theory and practice of personnel security measures. The purpose of the article is to identify and classify the ideas of the main threats to personnel security of the region (the research is carried out on the example of the Irkutsk region. On the basis of the content analysis of Russian regulatory legal acts and scientific publications, external and internal threats to personnel security of the region are highlighted. As a result, the list of threats to personnel security of the region consisting of 37 stands is composed. The political, economic, demographic, social, technical and technological, ecological, legal, ethnocultural forms of threats are demonstrated. The authors came to the conclusion that the internal threats to personnel security of the region (first of all socio-economic are dominant. An assessment of the urgency and relevance of the threats to the personnel security of the region is given. With the use of the technology of the hierarchical factorial analysis, the types of threats (factors of the lowest level were identified and their influence on the general level of the urgency of personnel security threats (a factor of the highest level is estimated. It is revealed that legal threats, as well as threats caused by the low labour potential of the region, have the most significant impact on the estimation of the urgency of threats. The study applies the following analysis methods — a content analysis, the analysis of linear and cross-distribution, hierarchical factor and correlation analysis. The analysis is based on the data of the expert survey conducted in the Irkutsk region (2015. To determine the relationship (coherence of the expert evaluations, the Kendall’s coefficient of concordance is calculated. The received results can be used for studying

1994-01-01

Substantial progress has been made in building cooperation in the Asia-pacific region in remarkably short period of time. Problems of regional disarmament are analysed by linking the economic and security issues. International cooperation regimes, whether in the military sphere, such as the Non-proliferation treaty, or in the trade sphere such as the General Agreement on Tariffs and Trade, inevitably impose restrictions on the autonomy of member States. The integrity of the regime depends on countries' acceptance of the obligations it imposes. The task ahead is to convince all countries in the region that cooperation in the security sphere will be of even greater long-term benefit

2015-01-01

Full Text Available The paper deals with development of methods and tools for mathematical and computer modeling of the multilevel network-centric control systems of regional security. This research is carried out under development strategy implementation of the Arctic zone of the Russian Federation and national safeguarding for the period before 2020 in the Murmansk region territory. Creation of unified interdepartmental multilevel computer-aided system is proposed intended for decision-making information support and socio-economic security monitoring of the Arctic regions of Russia. The distinctive features of the investigated system class are openness, self-organization, decentralization of management functions and decision-making, weak hierarchy in the decision-making circuit and goal generation capability inside itself. Research techniques include functional-target approach, mathematical apparatus of multilevel hierarchical system theory and principles of network-centric control of distributed systems with pro-active components and variable structure. The work considers network-centric management local decisions coordination problem-solving within the multilevel distributed systems intended for information support of regional security. The coordination problem-solving approach and problem formalization in the multilevel network-centric control systems of regional security have been proposed based on developed multilevel recurrent hierarchical model of regional socio-economic system complex security. The model provides coordination of regional security indexes, optimized by the different elements of multilevel control systems, subject to decentralized decision-making. The model specificity consists in application of functional-target technology and mathematical apparatus of multilevel hierarchical system theory for coordination procedures implementation of the network-centric management local decisions.

Regional collaboration has been identified as a potential facilitator of public health preparedness efforts. The Urban Area Security Initiative (UASI) grant program, administered by the Federal Emergency Management Agency (FEMA) since 2003, has provided 64 high-risk metropolitan areas funding to enhance their regional preparedness capabilities. This study describes informal and formal regional collaboration infrastructure, as well as regional collaboration-related activities and assessment methods, in FFY2010 UASI regions. A cross-sectional online survey was administered via Survey Monkey from September through December 2013. Points of contact from FFY2010 funded UASI metropolitan areas completed the survey, with a response rate of 77.8% (n=49). Summary statistics were calculated to describe the current informal and formal regional collaboration infrastructure. Additionally, the cross-sectional survey collected rates of agreement with 8 collaborative preparedness statements at 3 time points. The survey found that UASI regions are engaging in collaborative activities and investments to build capabilities, with most collaboration occurring in the prevention, protection, and response mission areas. Collaborative relationships in preparedness among emergency managers and municipal chief executive officers improved during the FFY2010 UASI performance period compared to the pre-UASI award period, with lasting effects. The majority of UASI regions reported conducting independent assessments of capabilities and their measurement at the UASI region level. Urban areas that received a FFY2010 UASI grant award are engaging in collaborative activities and have established interjurisdictional relationships in preparedness. The use of grant funds to encourage collaboration in preparedness has the potential to leverage limited resources and promote informed investments.

2018-02-01

In this paper, a security enhancement for double random phase encoding (DRPE) by introducing a rear-mounted phase masking procedure is presented. Based on exhaustively studying the cryptanalysis achievements of DRPE and its variants, invalidation of the second lens, which plays a critical role in cryptanalyzing processes, is concluded. The improved system can exploit the security potential of the second lens and consequently strengthen the security of DRPE. Experimental results and security analyses are presented in detail to demonstrate the security potential of the proposed cryptosystem.

Elena Nikolaevna Antamoshkina

2015-12-01

Full Text Available The article substantiates the author’s method of analysis of the regional food security and its approbation on the example of the Southern Federal District. The author’s goal was to develop a comprehensive universal method of analysis of the regional food security. To achieve this goal the following steps were required: to develop a system of indicators to measure food security at the regional level; to define criteria for assessing regional food security; to synthesize model analysis and evaluation of food security in the region. The paper presents an algorithm for the phased application of methodology for assessing regional food security. The recommended indicators and criteria for assessing regional food security are consistent with the parameters defined by the Doctrine of food security in Russia, and take into account the requirements of the WTO. The proposed method was tested on data from the largest regions of the Southern Federal District, which allowed a comparison of the level of food security in the regions of the spatial and temporal perspective. Comparison was made on the basis of an integrated assessment of the level of food security in the regions. The theoretical significance consists in the meaningful complement to research models and tools for analysis of food security at the regional level of the economy in terms of justification of indicators and criteria for assessing food security in the region in terms of Russia’s participation in the WTO. The practical significance is in developing and testing the proposed method based on an assessment of indicators of food security in SFD.

Comparison of the Efficiency of Budget Financing and the Social Security of a Region

Full Text Available In the article, the theoretical and economic aspects of the category “security” are considered, the distinction between philosophical and socio-economic approaches to the understanding of social security is drawn. From the point of view of the system approach, the place of social security for national security protection is determined. The theoretical content of the category “social security” is shown; in the authors’ treatment, the specifying concepts such as “social risks”, “danger”, “threat” are given. For the purpose of risks identification (deviations and the revealing of the factors of inefficient financing, the methodological tools for the assessment of the social security of a region are proposed. These tools are based on the integrated assessment of the regional socio-economic indexes and the indexes assessing the budgetary financing of the territory. The methodical approach offered by the authors is based on the detection of dependencies between the social and financial security of a region. As estimates, the indicators reflecting the level of social security in the territory of residence are chosen: income, expenses of the consolidated budget of a region, growth rate of gross regional product, rate of natural population growth, level of unemployment, population share with the income below living level. This approach is approved on the example of Perm Krai and Sverdlovsk region; the regularities, the favourable and adverse periods for social security of the region are revealed. The received estimates are ranged depending on a temporary log of growth (fall, elasticity and sensitivity to the budget financing. The results of the assessment have shown that, from the point of view of social security protection, Perm Krai has entered a stage of deep recession, which started in 2012. Similar tendencies are observed in the Sverdlovsk region. Nevertheless, considering both a visible variety and the dominating influence of

An empirical application of regional security complex theory on eastern partnership region

Full Text Available Eastern Partnership (EaP is a very dynamic region. If a year ago the EaP was seen as an authentic and vibrant „laboratory” of democracy building, overcoming the remains of the totalitarian state and putting the basis of a free and pluralist society, nowadays the Eastern Partnership is seen as an „out-dated” approach of the EU. However, Eastern Partnership is visible on European political arena and the big powers (USA, Russia and the EU pay attention more and more to the evolution of EaP countries. Moreover, it seems to be a confrontation between Russia and Western powers regarding the political and geopolitical orientation of EaP countries. Kremlin tries actively to stop the efforts of the EaP to close to the EU and on the other side, the EU as well as the USA encourage EaP countries to implement reforms in order to build their democracy. This paper aims to analyse the Eastern Partnership in terms of security complex, trying to argue that Eastern Partnership countries at this phase don’t form a Regional Security Complex and the EU and USA should rethink its approach towards this region.

An Enhanced Erasure Code-Based Security Mechanism for Cloud Storage

Full Text Available Cloud computing offers a wide range of luxuries, such as high performance, rapid elasticity, on-demand self-service, and low cost. However, data security continues to be a significant impediment in the promotion and popularization of cloud computing. To address the problem of data leakage caused by unreliable service providers and external cyber attacks, an enhanced erasure code-based security mechanism is proposed and elaborated in terms of four aspects: data encoding, data transmission, data placement, and data reconstruction, which ensure data security throughout the whole traversing into cloud storage. Based on the mechanism, we implement a secure cloud storage system (SCSS. The key design issues, including data division, construction of generator matrix, data encoding, fragment naming, and data decoding, are also described in detail. Finally, we conduct an analysis of data availability and security and performance evaluation. Experimental results and analysis demonstrate that SCSS achieves high availability, strong security, and excellent performance.

Full Text Available In today’s society, cloud computing has significantly impacted nearly every section of our lives and business structures. Cloud computing is, without any doubt, one of the strategic directions for many companies and the most dominating infrastructure for enterprises as long as end users. Instead of buying IT equipment (hardware and/or software and managing it themselves, many organizations today prefer to buy services from IT service providers. The number of service providers increase dramatically and the cloud is becoming the tools of choice for more cloud storage services. However, as more personal information and data are moved to the cloud, into social media sites, DropBox, Baidu WangPan, etc., data security and privacy issues are questioned. Daily, academia and industry seek to find an efficient way to secure data migration in the cloud. Various solution approaches and encryption techniques have been implemented. In this work, we will discuss some of these approaches and evaluate the popular ones in order to find the elements that affect system performance. Finally, we will propose a model that enhances data security and privacy by combining Advanced Encryption Standard-256, Information Dispersal Algorithms and Secure Hash Algorithm-512. Our protocol achieves provable security assessments and fast execution times for medium thresholds.

Task to protect network and data security is not simple and easy. The more advance ICT technology available in the market, the more dependability to the knowledge, skills and appropriate tools would be in order one to cater these threats. Cyber security threats can be considered almost impossible to be demolished or at least to be avoided totally and what we really need is technical capabilities that may include appropriate knowledge and tools to reduce the cyber threats in the organization. Email is one of the important today's application that is being used by many people all around the globe either they are in corporate organizations, government bodies, students and teachers. The total number of worldwide email accounts is expected to increase from 3.3 billion accounts in 2012 to over 4.3 billion accounts by year-end 2016. This represents an average annual growth rate of 6% over the next four years [1]. Parallel with the increment of the usage, number of abusive and misuse of the email is also reported either in the form of spamming, delivery of malicious file attachments, phishing and others. These show the importance to tighten up the security of the email. This paper will discuss and share actions that have been taken by IT Center to enhance the security of official email application.

Full Text Available The article is aiming at the study of environmental hazards in Zhytomir region. Its main objective is to identify the set of adverse factors affecting the state of danger and compose a necessary starting material for the prediction of possible negative consequences, their nature and extent. The matter of special importance for the study of the phenomenon of security is the security classification. First of all, the forms (system of security in relation to the forces and processes of natural, social and technical character should be distinguished. They can be defined as systems of geo-bio-physical, social and technical security. The classification of security can be determined in many ways, for example, in relation to the object of security; in relation to the subject of security; according to the problem indication; according to the functional indication. Security is a distinctive characteristic and prerequisite of life, progressive development and viability of real-world objects. The methodology of its evaluation is based on the states of the essence of natural and anthropogenic environmental pollution, the standard requirements for the quality of environmental objects and standards of acceptable contamination. The assessment of ecological security of the environment is the quantitative measure of parameters of environmental pollution dangers, threats and risks of natural character as well as the state of anthropogenic security. This assessment is carried out according to the methods and ways to measure environmental parameters. For this purpose it is important to know the factors of danger and the system of indicators that characterizes all natural and environmental phenomena and processes of geo-ecological dangers, natural environmental conditions, ecological condition. The system of natural and industrial environmental indicators consists of the indicators which characterize all phenomena and processes of geo-ecological dangers of natural

Moore, Judy Hennessey; Whitley, John B.; Chellis, Craig (Pacific Disaster Center, Kihei, HI)

2005-06-01

In October of 2003 experts involved in various aspects of homeland security from the Pacific region met to engage in a free-wheeling discussion and brainstorming (a 'fest') on the role that technology could play in winning the war on terrorism in the Pacific region. The result was a concise and relatively thorough definition of the terrorism problem in the Pacific region, emphasizing the issues unique to Island nations in the Pacific setting, along with an action plan for developing working demonstrations of advanced technological solutions to these issues. Since PacFest 2003, the maritime dimensions of the international security environment have garnered increased attention and interest. To this end, PacFest 2004 sought to identify gaps and enabling technologies for maritime domain awareness and responsive decision-making in the Asia-Pacific region. The PacFest 2004 participants concluded that the technologies and basic information building blocks exist to create a system that would enable the Pacific region government and private organizations to effectively collaborate and share their capabilities and information concerning maritime security. The proposed solution summarized in this report integrates national environments in real time, thereby enabling effective prevention and first response to natural and terrorist induced disasters through better use of national and regional investments in people, infrastructure, systems, processes and standards.

Status and determinants of small farming households' food security and role of market access in enhancing food security in rural Pakistan.

Directory of Open Access Journals (Sweden)

Umar Ijaz Ahmed

Full Text Available In most of the developing countries, lack of resources and little market accessibility are among the major factors that affect small farming household food security. This study aims to investigate the status of small farming households' food security, and its determinants including the role of market accessibility factors in enhancing food security at household level. In addition, this study also determines the households' perception about different kinds of livelihoods risks. This study is based on a household survey of 576 households conducted through face-to-face interviews using structured interviews in Punjab, Pakistan. Food security status is calculated using dietary intake method. The study findings show that one-fourth of the households are food insecure. The study findings reveal that farm households perceive increase in food prices, crop diseases, lack of irrigation water and increase in health expenses as major livelihood risks. Further, the results of logistic regression show that family size, monthly income, food prices, health expenses and debt are main factors influencing the food security status of rural households. Furthermore, the market accessibility factors (road distance and transportation cost do significantly affect the small farming household food security. The results suggest that local food security can be enhanced by creating off-farm employment opportunities, improved transportation facilities and road infrastructure.

Nuclear-weapon-free zones: Pursuing security, region by region. Conference of States Parties and Signatories of treaties that establish nuclear-weapon-free zones

International Nuclear Information System (INIS)

ElBaradei, M.

2005-01-01

The development of nuclear-weapon-free zones, over the past four decades, is a testament to what nations can do, region by region, to achieve common security objectives. In fact, when considering the history of nuclear non-proliferation efforts, it might be said that here in Mexico City is w here it all began . The 1967 Treaty of Tlatelolco was the first multilateral treaty to establish a region free of nuclear weapons and a requirement for comprehensive IAEA safeguards for its parties - and clearly gave impetus to the conclusion of the Treaty on the Non-Proliferation of Nuclear Weapons. Nuclear-weapon-free zones provide tangible security benefits. They help to reassure the larger international community of the peaceful nuclear intentions of countries in these regions. They provide their members with security assurances against the use, or threat of use, of nuclear weapons by a nuclear-weapon State. They include control mechanisms for dealing with non-compliance in a regional setting. And in all cases, they prohibit the development, stationing or testing of nuclear weapons in their respective regions. An important benefit of these zones is that they open a forum for expanded regional dialogue on issues of security. Because the causes of insecurity vary from region to region, security solutions do not come in a 'one-size-fits-all' package. It is for this reason that regional dialogues, as we see in the nuclear-weapon-free zones, are so beneficial. It is clear that such treaties, and such security dialogues, would be invaluable in other areas of the world, such as the Middle East and the Korean Peninsula. Since the end of the Cold War, the international security landscape has undergone dramatic changes. For example, the rise in terrorism, the discovery of clandestine nuclear programmes, and the emergence of covert nuclear procurement networks have heightened our awareness of vulnerabilities in the nuclear non-proliferation regime. This statement focuses on two issues

Full Text Available The interest of Western countries in the Arctic region is growing with each new statement about the sharp climate change and the melting of the Arctic Ocean’s glaciers. In addition to the threats related to the environmental situation in the Arctic zone, the desire to participate in shelf research and development, the potential of using the sea routes of the region by both the Arctic and non-Arctic states creates threats to the security of the Nordic countries.The coastal states, which in case of the escalation of tensions will be in the midst of a regional conflict in the Arctic, are Norway and Denmark. Therefore, the analysis of a level of Norwegian and Danish military security against a backdrop of increasing confrontation between Russia and West and changing climate situation in the region is urgent ., Nevertheless, to ensure a necessary level of defence capability as well as security of borders and zones of exceptional economic interests in the conditions of low temperatures is not so easy. This article examines the Norwegian and Danish approaches to the new military security challenges in the Arctic region. The paper contains examination of the doctrinal basis of military security along with the main documents that form the security concepts of the two countries in the Arctic region, and the reports of the defense ministries and scientific institutions surveys of military activities in the Arctic.Three directions of coastal countries’ policy making in the issues of military security were chosen for comparison. Firstly, the relationships with the USA, the leader of the North Atlantic alliance, which allow us to determine the significance of Norway and Denmark in building NATO security in the north. Secondly, the relationships with the EU and separately with the Nordic countries are considered. This case shows the level of involvement of the European community in the issue of ensuring the Arctic security . Thirdly, the relationships with

Full Text Available Ecological security and environmental sustainability are the foundations of sustainable development. With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem services. In this paper, considering the security of water resources, biodiversity conservation, disaster avoidance and protection and natural recreation, an integrated index of eco-space importance was established and a method for identifying key eco-space was created using GIS, with Lanzhou City, China as a case study. The results show that the area of core eco-space in the Lanzhou City is approximately 50,908.7 hm2, accounting for 40% of the region’s total area. These areas mainly consist of geological hazard protection zones and the core zones of regional river systems, wetlands, nature reserves, forest parks and scenic spots. The results of this study provide some guidance for the management of ecological security, ecological restoration and environmental sustainability.

Li, Congcong; Zhang, Xi; Wang, Haiping; Li, Dongfeng

2018-01-11

Vehicular sensor networks have been widely applied in intelligent traffic systems in recent years. Because of the specificity of vehicular sensor networks, they require an enhanced, secure and efficient authentication scheme. Existing authentication protocols are vulnerable to some problems, such as a high computational overhead with certificate distribution and revocation, strong reliance on tamper-proof devices, limited scalability when building many secure channels, and an inability to detect hardware tampering attacks. In this paper, an improved authentication scheme using certificateless public key cryptography is proposed to address these problems. A security analysis of our scheme shows that our protocol provides an enhanced secure anonymous authentication, which is resilient against major security threats. Furthermore, the proposed scheme reduces the incidence of node compromise and replication attacks. The scheme also provides a malicious-node detection and warning mechanism, which can quickly identify compromised static nodes and immediately alert the administrative department. With performance evaluations, the scheme can obtain better trade-offs between security and efficiency than the well-known available schemes.

Jung, Jaewook; Moon, Jongho; Lee, Donghoon; Won, Dongho

2017-03-21

At present, users can utilize an authenticated key agreement protocol in a Wireless Sensor Network (WSN) to securely obtain desired information, and numerous studies have investigated authentication techniques to construct efficient, robust WSNs. Chang et al. recently presented an authenticated key agreement mechanism for WSNs and claimed that their authentication mechanism can both prevent various types of attacks, as well as preserve security properties. However, we have discovered that Chang et al's method possesses some security weaknesses. First, their mechanism cannot guarantee protection against a password guessing attack, user impersonation attack or session key compromise. Second, the mechanism results in a high load on the gateway node because the gateway node should always maintain the verifier tables. Third, there is no session key verification process in the authentication phase. To this end, we describe how the previously-stated weaknesses occur and propose a security-enhanced version for WSNs. We present a detailed analysis of the security and performance of our authenticated key agreement mechanism, which not only enhances security compared to that of related schemes, but also takes efficiency into consideration.

Security Enhancement for Multicast over Internet of Things by Dynamically Constructed Fountain Codes

Qinghe Du

2018-01-01

Full Text Available The Internet of Things (IoT is expected to accommodate every object which exists in this world or likely to exist in the near future. The enormous scale of the objects is challenged by big security concerns, especially for common information dissemination via multicast services, where the reliability assurance for multiple multicast users at the cost of increasing redundancy and/or retransmissions also benefits eavesdroppers in successfully decoding the overheard signals. The objective of this work is to address the security challenge present in IoT multicast applications. Specifically, with the presence of the eavesdropper, an adaptive fountain code design is proposed in this paper to enhance the security for multicast in IoT. The main novel features of the proposed scheme include two folds: (i dynamical encoding scheme which can effectively decrease intercept probability at the eavesdropper; (ii increasing the transmission efficiency compared with the conventional nondynamical design. The analysis and simulation results show that the proposed scheme can effectively enhance information security while achieving higher transmission efficiency with a little accredited complexity, thus facilitating the secured wireless multicast transmissions over IoT.

Full Text Available The unipolar world breaking and the tightening of geopolitical struggle led to destructive military-political processes in different regions of the world. In conditions of instability along the perimeter of Russia's borders the significance of the Caucasus region increases, especially in geo-strategic and geoeconomic perspectives. The efforts of world politics actors for the transformation of the region environment increase substantially. As a result the dynamics and the scope of the proceeding military-political processes in the Caucasus are complicated. The failures in the assessment and the prediction of the processes development influence on the safety of Russia. Wrong gradation of existing threats and challenges can lead to disastrous and irreversible consequences for state security. Designated circumstances caused the need for the expert survey on assessing the impact of the current military-political processes in the Caucasus region on the security of the Russian state and necessity for the concretization of military dangers and threats, due to political and military developments in the Caucasus. An expert survey was conducted in June 2014. During it authors interviewed 40 Russian and foreign experts representing Federal and regional authorities, academic community, research centers, analytical structures. Implementation of the survey allowed to identify the experts positions and the degree of their coherence on the military-political processes in the Caucasus region and their impact on the modern Russia security. As a result the degree of destructiveness of the regional military-political processes was fixed. We conclude that anti-Russian processes in the countries of the Caucasus continue to determine the overall geopolitical situation, including in the military-political sphere. The reason is mainly seen in interests clashing of Russia and countries of the "Atlantic world." Analysis of the military-political processes in the Caucasus

A regional proposal for reinforcing nuclear and radiological security

This paper gives information about the phenomenon of globalization and the regional process of integration that have generated new and challenging characteristics in criminal actions, that has generated a trans national dimension. In this frame, the illicit trafficking of radioactive material is a matter of concern. After the terrorist attacks of September 11, 2001, it is a new reality that for certain terrorist groups, exposition to radiation ionizing with the purpose of committing a terrorist act is not more an obstacle. The use of a 'dirty bomb'. by terrorists is considered probable. The orphan sources represent a serious threat to security and must be: identified, located, recovered, and assured. Many radioactive materials with hundreds of applications in medicine, research and industry are lost or robbed. There are countries that have not a registry of such orphan sources. The IAEA Illicit Trafficking Data Base (ITDB) was established in 1993.There were 103 confirmed incidents of illicit trafficking and other unauthorized activities involving nuclear and radioactive materials in 2005. Nevertheless INTERPOL registers a much greater number of cases. The IAEA tries to increase the capacity of Member States to protect their facilities and nuclear fuels, storage and transport against acts of nuclear terrorism. In this paper I propose the creation of an Inter-American Committee Specialized in the Prevention and Control of the Illicit Trafficking of Radioactive and Nuclear Material at Pan-American level and within the framework of O.A.S., according to the Chart of the Organization of American States , and considering the respect to the sovereignty of the States and the principle of not intervention, with the purpose of developing the cooperation in order to prevent and to prevent and to control the illicit trafficking of radioactive and nuclear material. Its principal objective would be to develop a cooperation and a common approach of nuclear and radiological

The International Legal Framework for Nuclear Security

International Nuclear Information System (INIS)

2011-01-01

The term 'nuclear security' is generally accepted to mean 'the prevention and detection of, and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear material, other radioactive substances or their associated facilities.' While the ultimate responsibility for nuclear security within a State rests entirely with that State, the need for regional and international cooperation has become increasingly evident with the growing recognition that the ability to prevent, detect and respond to the threats to nuclear security within one State is affected by the adequacy and effectiveness of nuclear security measures taken by other States, particularly when nuclear material is transported across national frontiers. Since the early 1970s, the IAEA has been called upon to play an ever increasing role in assisting States, upon request, to strengthen their national legal infrastructures and physical protection systems, as well as to facilitate regional and international efforts to enhance nuclear security, including measures to protect against nuclear terrorism. This publication brings together the legally binding primary international instruments and the internationally accepted non-binding instruments that constitute the international legal framework for nuclear security. It does not discuss the safety and safeguards related instruments, which also form a part of the broader legal framework for nuclear security. By setting out the legislative bases for the mandate of the IAEA in the area of nuclear security, it is hoped that this publication will increase awareness of the IAEA's role in facilitating national, regional and international efforts to enhance nuclear security , including measures to protect against nuclear terrorism. It is also intended to serve as a guide in carrying out the IAEA's nuclear security mandate and functions assigned to it under these instruments, including in the elaboration of nuclear security

During the last few years, wireless networks have been increasingly used both inside hospitals and in patients' homes to transmit medical information. In general, wireless networks suffer from decreased security. However, digital watermarking can be used to secure medical information. In this study, we focused on combining wireless transmission and digital watermarking technologies to better secure the transmission of medical images within and outside the hospital. We utilized an integrated system comprising the wireless network and the digital watermarking module to conduct a series of tests. The test results were evaluated by medical consultants. They concluded that the images suffered no visible quality degradation and maintained their diagnostic integrity. The proposed integrated system presented reasonable stability, and its performance was comparable to that of a fixed network. This system can enhance security during the transmission of medical images through a wireless channel.

2008-10-01

Full Text Available The expansion of sustainable development initiatives since the 1990’s reflected an emphasis on integrated solutions to economic development, socio-political stability and environmental health in the global community. In the same context the traditional concept of security needed to be open in two directions. First, the notion of security should no longer be applied only to the military realm, but also to the economic, the societal, the environmental, and the political fields. Second, the referent object of the “security” should not be conceptualized solely in terms of the state, but should embrace the individual below the state, and the international system above it. The forests industry timber certification in Asia-Pacific region has been selected as a case study because it is an excellent example to illustrate the links between the sustainable development and the environmental security, including also certain elements of economic security. This article is presenting a critical overview of the forest industry and the status of timber certification globally, with an emphasis on Asia – Pacific countries applying the Systemic Thinking approach. In conclusion, an outlook is presented concerning the future of timber certification and possible impacts on security and sustainable development.

Brazilian Policy and the Creation of a Regional Security Complex in the South Atlantic: Pax Brasiliana?

Directory of Open Access Journals (Sweden)

Beatriz Rodrigues Bessa Mattos

Full Text Available Abstract Over the past five years, the South Atlantic region has become a central element of Brazilian security policy, with Brazil actively supporting the notion of a trans-oceanic security consciousness involving African littoral states. It has invested in diplomatic initiatives such as the Zone of Peace and Cooperation of the South Atlantic (ZPCSA, or ZOPACAS, and extensive military co-operation with West African states such as São Tomé e Príncipe, Namibia and Cape Verde. Its internal security and defence policy documents have repeatedly been updated to reflect this dimension, and now provide the foundation for advancing these initiatives. This policy thrust is directed at securing Brazil’s offshore oil assets, and limiting the influence of what it has termed ‘extra-regional powers’ such as the P-5. This article highlights these initiatives and reviews the prospects for this policy by examining the plausibility of the South Atlantic region as a regional security complex in the sense coined by Buzan and Wæver. The analysis is based on the role of geographical and linguistic proximity in international relations, and the impact of multilateral bodies on building support for a regional approach to security governance.

Full Text Available Wireless sensor networks (WSNs consist of sensors, gateways and users. Sensors are widely distributed to monitor various conditions, such as temperature, sound, speed and pressure but they have limited computational ability and energy. To reduce the resource use of sensors and enhance the security of WSNs, various user authentication protocols have been proposed. In 2011, Yeh et al. first proposed a user authentication protocol based on elliptic curve cryptography (ECC for WSNs. However, it turned out that Yeh et al.’s protocol does not provide mutual authentication, perfect forward secrecy, and key agreement between the user and sensor. Later in 2013, Shi et al. proposed a new user authentication protocol that improves both security and efficiency of Yeh et al.’s protocol. However, Shi et al.’s improvement introduces other security weaknesses. In this paper, we show that Shi et al.’s improved protocol is vulnerable to session key attack, stolen smart card attack, and sensor energy exhausting attack. In addition, we propose a new, security-enhanced user authentication protocol using ECC for WSNs.

2010-04-01

Full Text Available The last three decades have witnessed a spectacular (and not easily sustainable increase in the global demand for energy. This trend has a particular significance in East Asia owing to its heavy industrialisation, which is promoting intense regional growth, on top of the already delicate balance of security in the region and the traditional refusal by the region’s states to delegate power and management to supranational bodies. The aim of this article is to analyse the impact of East Asia’s energy needs on security and on the instruments of order and governance that have been developed in the region up until the present time. Thus, the article is divided into two parts; the first analyses East Asia’s energy programme and its most significant features: 1 a high dependence on oil imports from other regions, especially the Middle East; 2 a persistence of high dependency on pollutant fossil fuels; and 3 a high degree of energy insecurity. Meanwhile, the second part assesses the impact of energy on regional relations in different areas of security and guidelines for regional government: 1 the securitisation of energy and of the environment; 2 the reactivation of certain maritime conflicts; 3 the transformation of certain threats, and conventional and non-conventional challenges to regional security; 4 the rise of non-state actors (mainly environmental businesses and NGOs in East Asia’s international relations; 5 the maintaining of bilateralism and the promotion of multilateral initiatives; and 6 the emergence of new extra-regional geopolitical links and balances.

Recently, many biometrics-based user authentication schemes using smart cards have been proposed to improve the security weaknesses in user authentication system. In 2011, Das proposed an efficient biometric-based remote user authentication scheme using smart cards that can provide strong authentication and mutual authentication. In this paper, we analyze the security of Das's authentication scheme, and we have shown that Das's authentication scheme is still insecure against the various attacks. Also, we proposed the enhanced scheme to remove these security problems of Das's authentication scheme, even if the secret information stored in the smart card is revealed to an attacker. As a result of security analysis, we can see that the enhanced scheme is secure against the user impersonation attack, the server masquerading attack, the password guessing attack, and the insider attack and provides mutual authentication between the user and the server.

Full Text Available Nowadays, the common denominator of involvement of the EastCentral Europe in the international arena, and above all, the premise determining community of interest expressed in the European Union is the migration crisis. Despite the different circumstances of activity in the context of the migration crisis, states in the region express similar opinions on the consequences of immigration for security in the region. Above all, they emphasise the implications of immigration for the internal security of states. Given the complex nature of migration, this article focuses on the phenomenon of immigration in the EU, determining the causes of the escalation of the influx of immigrants and, above all, identifying the consequences for the security of states of East-Central Europe.

Full Text Available The monitoring, control, and security guarantee for the communication in the wireless sensor networks (WSNs are currently treated as three independent issues and addressed separately through specialized tools. However, most cases of WSNs applications requires the network administrator change the network configuration in a very short time to response to the change of observed phenomenon with security guarantee. To meet this requirement, we propose a security enhanced monitoring and control platform named SecMAS for WSNs, which provides the real-time visualization about network states and online reconfiguration of the network properties and behaviours in a resource-efficient way. Besides, basic cryptographic primitives and part of the anomaly detection functionalities are implemented in SecMAS to enabling the secure communication in WSNs. Furthermore, we conduct experiments to evaluate the performance of SecMAS in terms of the latency, throughput, communication overhead, and the security capacity. The experimental results demonstrate that the SecMAS system achieves stable, efficient and secure data collection with lightweight quick-response network control.

Guidelines and recommendations for regional approaches to disarmament within the context of global security provide both a conceptual framework within which to pursue arms control in South Asia and a variety of concrete mechanisms or tools to carry out the task. However, they cannot operate independently of a broader process of political accommodation, which might be named as 'cooperative security building'. That process, however embryonic, is under way across Asia Pacific region

Ensuring reliable communication in next-generation space networks requires a novel network management system to support greater levels of autonomy and greater awareness of the environment and assets. Intelligent Automation, Inc., has developed a security-enhanced autonomous network management (SEANM) approach for space networks through cross-layer negotiation and network monitoring, analysis, and adaptation. The underlying technology is bundle-based delay/disruption-tolerant networking (DTN). The SEANM scheme allows a system to adaptively reconfigure its network elements based on awareness of network conditions, policies, and mission requirements. Although SEANM is generically applicable to any radio network, for validation purposes it has been prototyped and evaluated on two specific networks: a commercial off-the-shelf hardware test-bed using Institute of Electrical Engineers (IEEE) 802.11 Wi-Fi devices and a military hardware test-bed using AN/PRC-154 Rifleman Radio platforms. Testing has demonstrated that SEANM provides autonomous network management resulting in reliable communications in delay/disruptive-prone environments.

Water security is an important basis for making water security protection strategy, which concerns regional economic and social sustainable development. In this paper, watershed water security evaluation index system including 3 levels of 5 criterion layers (water resources security, water ecological security and water environment security, water disasters prevention and control security and social economic security) and 24 indicators were constructed. The entropy weight method was used to determine the weights of the indexes in the system. The water security index of 2000, 2005, 2010 and 2015 in Yellow River basin were calculated by linear weighting method based on the relative data. Results show that the water security conditions continue to improve in Yellow River basin but still in a basic security state. There is still a long way to enhance the water security in Yellow River basin, especially the water prevention and control security, the water ecological security and water environment security need to be promoted vigorously.

There are several technologies to secure water resources, including the desalination of seawater, recycling of industrial water and reuse of wastewater. However precipitation enhancement is the only way we can create a large amount of water for industrial use, for example, water for irrigation, provided we find clouds suitable for cloud seeding and apply appropriate and effective methods to increase precipitation. Therefore, rain enhancement research is critical in the quest for new water security options and innovative solutions in the UAE and other arid and semi-arid regions. The main objective of our project is to better evaluate, and ultimately improve, the effectiveness of rain enhancement in the UAE and other arid and semi-arid regions using hygroscopic and glaciogenic seeding techniques. One of the major questions regarding rain enhancement today is the effectiveness of hygroscopic seeding for warm and supercooled convective clouds. Our research will investigate the microphysical processes in seeded and unseeded clouds using a combination of laboratory experiments, numerical simulations and in-situ aircraft measurements in order to decipher the mechanism responsible for precipitation augmentation due to hygroscopic seeding. In our research, major elements of cloud seeding, e.g., assessment of seedability, development of optimal seeding methods and evaluation of seeding effects, will be investigated in the most efficient and realistic way, within three years, using mainly the numerical models with the sophisticated seeding scheme, which is developed on a basis of laboratory experiments and then validated against in-situ and remote sensing observations. In addition to the research plan, the outcomes of the research projects, which will be made available to the public at the end of the project and benefit the broader society, is discussed.

Radiation hazards are trans-boundary. The prevention of accidents must be managed locally. But the awareness, preparedness, and the responsibilities in the case of emergencies must be managed at the local and regional level, and must rely on close interaction between the local and regional levels. The Baltic Sea Region contains over 40 nuclear reactors contributing to energy security, but also posing a potential threat to human, environmental, and political security. The aim of this paper is to integrate the four fields of security: health, environment, energy, and political by analysing awareness, preparedness responsibility and decision making related to nuclear installations. With increasing political, economical, cultural and physical (in term of energy infrastructure) integration, the region needs to take a comprehensive approach to create adequate structure for managing risks and thereby promote security.

Power system security enhancement through direct non-disruptive load control

Science.gov (United States)

Ramanathan, Badri Narayanan

The transition to a competitive market structure raises significant concerns regarding reliability of the power grid. A need to build tools for security assessment that produce operating limit boundaries for both static and dynamic contingencies is recognized. Besides, an increase in overall uncertainty in operating conditions makes corrective actions at times ineffective leaving the system vulnerable to instability. The tools that are in place for stability enhancement are mostly corrective and suffer from lack of robustness to operating condition changes. They often pose serious coordination challenges. With deregulation, there have also been ownership and responsibility issues associated with stability controls. However, the changing utility business model and the developments in enabling technologies such as two-way communication, metering, and control open up several new possibilities for power system security enhancement. This research proposes preventive modulation of selected loads through direct control for power system security enhancement. Two main contributions of this research are the following: development of an analysis framework and two conceptually different analysis approaches for load modulation to enhance oscillatory stability, and the development and study of algorithms for real-time modulation of thermostatic loads. The underlying analysis framework is based on the Structured Singular Value (SSV or mu) theory. Based on the above framework, two fundamentally different approaches towards analysis of the amount of load modulation for desired stability performance have been developed. Both the approaches have been tested on two different test systems: CIGRE Nordic test system and an equivalent of the Western Electric Coordinating Council test system. This research also develops algorithms for real-time modulation of thermostatic loads that use the results of the analysis. In line with some recent load management programs executed by utilities, two

A Taxonomy for Enhancing Usability, Flexibility, and Security of User Authentication

2017-12-01

Full Text Available Two technology trends – a move toward software defined capabilities and toward networked devices – support both unprecedented innovations and requirements for security. A fundamental aspect of security is user authentication, which allows devices and software applications to establish their user’s identity and identity is in turn used to establish which of its capabilities the user is authorized to access. While multiple authentication steps, known as multifactor authentication, are being used more widely throughout the military, government, businesses, and consumer sectors, the selection and implementation of which authentication factors to require is typically defined by security policy. Security policy is in turn typically established by a security organization that may have no formal metrics or means to guide its selection of authentication factors. This paper will present a taxonomy for describing authentication factors including important attributes that characterize authentication robustness to aid in the selection of factors that are consistent with the user’s mission. One particular authentication factor that I have developed will be discussed in the context of this taxonomy to motivate the need to broaden current definitions and security policies. The ultimate goal of this paper is to inspire the development of standards for authentication technologies to both support mission aware authentication innovation and to inform decision making about security policies concerning user authentication and authorization. Further, this paper aims to demonstrate that such an approach will fundamentally enhance both security and usability of increasingly networked, software-defined devices, equipment and software applications.

Global chemical security has been enhanced through the determined use and integration of both voluntary and legislated standards. Many popular standards contain components that specifically detail requirements for the security of materials, facilities and other vital assets. In this document we examine the roll of quality management standards and how they affect the security culture within the institutions that adopt these standards in order to conduct business within the international market place. Good manufacturing practices and good laboratory practices are two of a number of quality management systems that have been adopted as law in many nations. These standards are designed to protect the quality of drugs, medicines, foods and analytical test results in order to provide the world-wide consumer with safe and affective products for consumption. These standards provide no established security protocols and yet manage to increase the security of chemicals, materials, facilities and the supply chain via the effective and complete control over the manufacturing, the global supply chains and testing processes. We discuss the means through which these systems enhance security and how nations can further improve these systems with additional regulations that deal specifically with security in the realm of these management systems. We conclude with a discussion of new technologies that may cause disruption within the industries covered by these standards and how these issues might be addressed in order to maintain or increase the level of security within the industries and nations that have adopted these standards.

Security Enhancement of Wireless Sensor Networks Using Signal Intervals.

2017-04-02

Various wireless technologies, such as RF, Bluetooth, and Zigbee, have been applied to sensor communications. However, the applications of Bluetooth-based wireless sensor networks (WSN) have a security issue. In one pairing process during Bluetooth communication, which is known as simple secure pairing (SSP), the devices are required to specify I/O capability or user interference to prevent man-in-the-middle (MITM) attacks. This study proposes an enhanced SSP in which a nonce to be transferred is converted to a corresponding signal interval. The quantization level, which is used to interpret physical signal intervals, is renewed at every connection by the transferred nonce and applied to the next nonce exchange so that the same signal intervals can represent different numbers. Even if attackers eavesdrop on the signals, they cannot understand what is being transferred because they cannot determine the quantization level. Furthermore, the proposed model does not require exchanging passkeys as data, and the devices are secure in the case of using a fixed PIN. Subsequently, the new quantization level is calculated automatically whenever the same devices attempt to connect with each other. Therefore, the pairing process can be protected from MITM attacks and be convenient for users.

With the progress and the development of information technology, the internal data in medical organizations have become computerized and are further established the medical information system. Moreover, the use of the Internet enhances the information communication as well as affects the development of the medical information system that a lot of medical information is transmitted with the Internet. Since there is a network within another network, when all networks are connected together, they will form the "Internet". For this reason, the Internet is considered as a high-risk and public environment which is easily destroyed and invaded so that a relevant protection is acquired. Besides, the data in the medical network system are confidential that it is necessary to protect the personal privacy, such as electronic patient records, medical confidential information, and authorization-controlled data in the hospital. As a consequence, a medical network system is considered as a network requiring high security that excellent protections and managerial strategies are inevitable to prevent illegal events and external attacks from happening. This study proposes secure medical managerial strategies being applied to the network environment of the medical organization information system so as to avoid the external or internal information security events, allow the medical system to work smoothly and safely that not only benefits the patients, but also allows the doctors to use it more conveniently, and further promote the overall medical quality. The objectives could be achieved by preventing from illegal invasion or medical information being stolen, protecting the completeness and security of medical information, avoiding the managerial mistakes of the internal information system in medical organizations, and providing the highly-reliable medical information system.

To enhance the security in optical image encryption system and to protect it from the attackers, this paper proposes new digital spiral phase mask based on Fresnel Transform. In this cryptosystem the Spiral Phase Mask (SPM) used is a hybrid of Fresnel Zone Plate (FZP) and Radial Hilbert Mask (RHM) which makes the key strong and enhances the security. The different keys used for encryption and decryption purposed make the system much more secure. Proposed scheme uses various structured phase mask which increases the key space also it increases the number of parameters which makes it difficult for the attackers to exactly find the key to recover the original image. We have also used different keys for encryption and decryption purpose to make the system much more secure. The strength of the proposed cryptosystem has been analyzed by simulating on MATLAB 7.9.0(R2008a). Mean Square Errors (MSE) and Peak Signal to Noise Ratio (PSNR) are calculated for the proposed algorithm. The experimental results are provided to highlight the effectiveness and sustainability of proposed cryptosystem and to prove that the cryptosystem is secure for usage.

Full Text Available Information technology (IT security has become a major concern due to the growing demand for information and massive development of client/server applications for various types of applications running on modern IT infrastructure. How has security been taken into account and which paradigms are necessary to minimize security issues while increasing efficiency, reducing the influence on transmissions, ensuring protocol independency and achieving substantial performance? We have found cryptography to be an absolute security mechanism for client/server architectures, and in this study, a new security design was developed with the MODBUS protocol, which is considered to offer phenomenal performance for future development and enhancement of real IT infrastructure. This study is also considered to be a complete development because security is tested in almost all ways of MODBUS communication. The computed measurements are evaluated to validate the overall development, and the results indicate a substantial improvement in security that is differentiated from conventional methods.

An anonymous user authentication scheme allows a user, who wants to access a remote application server, to achieve mutual authentication and session key establishment with the server in an anonymous manner. To enhance the security of such authentication schemes, recent researches combined user's biometrics with a password. However, these authentication schemes are designed for single server environment. So when a user wants to access different application servers, the user has to register many times. To solve this problem, Chuang and Chen proposed an anonymous multiserver authenticated key agreement scheme using smart cards together with passwords and biometrics. Chuang and Chen claimed that their scheme not only supports multiple servers but also achieves various security requirements. However, we show that this scheme is vulnerable to a masquerade attack, a smart card attack, a user impersonation attack, and a DoS attack and does not achieve perfect forward secrecy. We also propose a security enhanced anonymous multiserver authenticated key agreement scheme which addresses all the weaknesses identified in Chuang and Chen's scheme.

2016-02-01

Full Text Available Inter‐basin water transfer projects (IBWTPs offer one of the most important means to solve the mismatch between supply and demand of regional water resources. IBWTPs have impacts on the complex ecosystems of the areas from which water is diverted and to which water is received. These impacts increase damage or risk to regional ecological security and human wellbeing. However, current methods make it difficult to achieve comprehensive analysis of the impacts of whole ecosystems, because of the long distance between ecosystems and the inconsistency of impact events. In this study, a model was proposed for the analysis of the impacts of IBWTPs on regional ecological security. It is based on the telecoupling framework, and the Driver‐Pressure‐State‐ Impact‐Response (DPSIR model was used to improve the analysis procedure within the telecoupling framework. The Middle Line of the South‐to‐North Water Diversion Project was selected as a case study to illustrate the specific analysis procedure. We realized that information sharing is a key issue in the management of regional security, and that the ecological water requirement, in the form of a single index, could be used to quantitatively assess the impacts on ecological security from IBWTPs.

Highlights: • Four dimensions and ten metrics are used for energy security assessment. • Both qualitative and quantitative metrics are considered for energy security. • AHP has been used to quantify qualitative metrics. • TOPSIS method has been used for prioritize the low-carbon energy sources. • Sensitivity analysis and integrated ranking have been carried out. - Abstract: This paper explores how low-carbon systems compare to each other in terms of their net effect on Chinese energy security, and how they ought to be ranked and strategized into an optimal and integrated resource plan. The paper utilizes Analytic Hierarchy Process (AHP) to first determine the relative performances of hydroelectricity, wind energy, solar energy, biomass energy, and nuclear power with respect to the energy security dimensions of availability, affordability, accessibility, and acceptability. Both qualitative and quantitative metrics are considered. It relies on AHP to calculate the relative weights of the qualitative metrics attached to these dimensions of energy security for each of our five low carbon energy sources. Then, energy security performance is determined by aggregating multiple, weighted metrics into a generic index based on the method of TOPSIS and then tweaked with a sensitivity analysis. Finally, an integrated method has been developed to rank the low-carbon energy systems from most to least important, with major implications for Chinese decision-makers and stakeholders. We conclude that hydroelectricity and wind power are the two low-carbon energy sources with the most potential to enhance China’s energy security. By contrast, nuclear and solar power have the least potential

The Extended Concept of Security and the Czech Security Practice

Full Text Available According to the extended concept of security, the nation state is no longer the sole privileged reference object of security. The traditional model of national security is developing from military terms to a broader concept which embraces the international, economic, social, environmental, and human rights dimensions of security. The meaning and relevance of the concept is being extended “upwards”, to international organisations, and “downwards”, to regional and local authorities, non-governmental organisations, communities, and individual citizens. This has immediate bearing on the everyday security reality of the Czech Republic. In international context, the “security frontier” of the Czech Republic is expanding, e.g. through the country’s involvement in UN and NATO security missions in conflict-ridden regions of Europe and the world. The country also helps enhance the internal security of the European Union, whose strength depends on its Member States’ willingness to “harmonise” the pursuit of their respective national security interests. This approach is especially important with regard to the principal security threats Europe faces and will continue to face in the future: terrorism and organised crime. It is vital that the Czech Republic have a well-working security system capable of responding effectively to a broad range of threats. This requirement applies first and foremost to the Police, the Fire and Rescue Service, and intelligence services. Unfortunately, with the present effectiveness of the Czech security system, much remains wishful thinking and, due to the lack of a comprehensive framework, a comparatively low level of protection against emergencies exists. Fight against crime is hampered by inefficient operation of the Police and judiciary. A thorough analysis of the aforementioned problems could provide basis for a broader public debate over the priorities and goals of Czech security policy, which should

Fog (from core to edge) computing is a newly emerging computing platform, which utilizes a large number of network devices at the edge of a network to provide ubiquitous computing, thus having great development potential. However, the issue of security poses an important challenge for fog computing. In particular, the Internet of Things (IoT) that constitutes the fog computing platform is crucial for preserving the security of a huge number of wireless sensors, which are vulnerable to attack. In this paper, a new unequal probability marking approach is proposed to enhance the security performance of logging and migration traceback (LM) schemes in tree-based wireless sensor networks (WSNs). The main contribution of this paper is to overcome the deficiency of the LM scheme that has a higher network lifetime and large storage space. In the unequal probability marking logging and migration (UPLM) scheme of this paper, different marking probabilities are adopted for different nodes according to their distances to the sink. A large marking probability is assigned to nodes in remote areas (areas at a long distance from the sink), while a small marking probability is applied to nodes in nearby area (areas at a short distance from the sink). This reduces the consumption of storage and energy in addition to enhancing the security performance, lifetime, and storage capacity. Marking information will be migrated to nodes at a longer distance from the sink for increasing the amount of stored marking information, thus enhancing the security performance in the process of migration. The experimental simulation shows that for general tree-based WSNs, the UPLM scheme proposed in this paper can store 1.12-1.28 times the amount of stored marking information that the equal probability marking approach achieves, and has 1.15-1.26 times the storage utilization efficiency compared with other schemes.

Full Text Available The article explores the issue on the perception of the concept “national security” areas, models and methods of its maintenance by the population. The author uses materials of the sociological survey conducted by the Laboratory of problems of increasing the efficiency of state and municipal management of the South-Russian Institute of Management – branch of the Russian Presidential Academy of National Economy and Public Administration. The survey was carried out with the participation of leading experts in various aspects of national security, representing 27 Russian higher educational institutions and research centers in Moscow, Astrakhan, Barnaul, Belgorod, Dushanbe, Krasnodar, Nizhny Novgorod, Omsk, Pyatigorsk, Rostov-on-Don, Saint Petersburg, Syktyvkar, Sochi, Ufa. It is noted that as a priority political governance model that implements the basic concept of national security, respondents identified a democratic model. Most respondents believe that a unified security model in the Russian regions is ineffective, and such model should be developed taking into account the specificity of each subject. The study showed that the public’s attention to the issue of national security is not sustainable, as determined by situational factors. It is proved that the motives of anxiety formed in the Russian public mind are not sustainable, and situational. Respondents see the economic cooperation more effective incentive to maintain national interests than by force. Estimation of the population of the priority issues of security shows that most respondents appreciate the organization of work to ensure the safety and anti-terrorism security in the sphere of national relations. The findings give grounds to assert that the focus of public attention to the problem of national security does not yet occupy the leading positions. To a greater extent, respondents focused on the issues of public safety, reducing threats and risks in their daily lives

Security Enhancement of Wireless Sensor Networks Using Signal Intervals

Full Text Available Various wireless technologies, such as RF, Bluetooth, and Zigbee, have been applied to sensor communications. However, the applications of Bluetooth-based wireless sensor networks (WSN have a security issue. In one pairing process during Bluetooth communication, which is known as simple secure pairing (SSP, the devices are required to specify I/O capability or user interference to prevent man-in-the-middle (MITM attacks. This study proposes an enhanced SSP in which a nonce to be transferred is converted to a corresponding signal interval. The quantization level, which is used to interpret physical signal intervals, is renewed at every connection by the transferred nonce and applied to the next nonce exchange so that the same signal intervals can represent different numbers. Even if attackers eavesdrop on the signals, they cannot understand what is being transferred because they cannot determine the quantization level. Furthermore, the proposed model does not require exchanging passkeys as data, and the devices are secure in the case of using a fixed PIN. Subsequently, the new quantization level is calculated automatically whenever the same devices attempt to connect with each other. Therefore, the pairing process can be protected from MITM attacks and be convenient for users.

To effectively improve the low contrast of human body region in the infrared images, a combing method of several enhancement methods is utilized to enhance the human body region. Firstly, for the infrared images acquired by Kinect, in order to improve the overall contrast of the infrared images, an Optimal Contrast-Tone Mapping (OCTM) method with multi-iterations is applied to balance the contrast of low-luminosity infrared images. Secondly, to enhance the human body region better, a Level Set algorithm is employed to improve the contour edges of human body region. Finally, to further improve the human body region in infrared images, Laplacian Pyramid decomposition is adopted to enhance the contour-improved human body region. Meanwhile, the background area without human body region is processed by bilateral filtering to improve the overall effect. With theoretical analysis and experimental verification, the results show that the proposed method could effectively enhance the human body region of such infrared images.

Physical Layer Built-In Security Analysis and Enhancement Algorithms for CDMA Systems

2007-01-01

Full Text Available Historically developed for secure communication and military use, CDMA has been identified as a major modulation and multiple-access technique for 3G systems and beyond. In addition to the wide bandwidth and low power-spectrum density which make CDMA signals robust to narrowband jamming and easy to be concealed within the noise floor, the physical layer built-in information privacy of CDMA system is provided by pseudorandom scrambling. In this paper, first, security weakness of the operational and proposed CDMA airlink interfaces is analyzed. Second, based on the advanced encryption standard (AES, we propose to enhance the physical layer built-in security of CDMA systems through secure scrambling. Performance analysis demonstrates that while providing significantly improved information privacy, CDMA systems with secure scrambling have comparable computational complexity and overall system performance with that of conventionally scrambled systems. Moreover, it is shown that by scrambling the training sequence and the message sequence separately with two independent scrambling sequences, both information privacy and system performance can be further improved. The proposed scheme can readily be applied to 3G systems and beyond.

In developing countries, the ability to provide adequate and reliable energy supplies is a key to sustainable economic development. The aim of this report is to study the energy supply security in both Southern Africa and South America and how these regions can participate in the international effort to combat climate change. This report showed that South Africa's energy sector mostly relies on carbon intensive coal while Brazil is mainly supplied by hydroelectricity. It was found that in both countries energy needs will increase significantly due to rising demand both internally and at a regional scale. However it was also shown that both Southern Africa and South America have important hydro, solar and wind renewable resources which could enhance their electricity security while minimizing their environmental impacts. This study demonstrated that Southern Africa and South America can enhance their electricity security through the use of renewable energies but that technology and financing is needed to develop the sector.

In 2004, Australia, through the Australian Nuclear Science and Technology Organisation (ANSTO), created the Regional Security of Radioactive Sources (RSRS) project and partnered with the U.S. Department of Energy's Global Threat Reduction Initiative (GTRI) and the International Atomic Energy Agency (IAEA) to form the Southeast Asian Regional Radiological Security Partnership (RRSP). The intent of the RRSP is to cooperate with countries in Southeast Asia to improve the security of their radioactive sources. This Southeast Asian Partnership supports objectives to improve the security of high risk radioactive sources by raising awareness of the need and developing national programs to protect and control such materials, improve the security of such materials, and recover and condition the materials no longer in use. The RRSP has utilized many tools to meet those objectives including: provision of physical protection upgrades, awareness training, physical protection training, regulatory development, locating and recovering orphan sources, and most recently - development of model security procedures at a model facility. This paper discusses the benefits of establishing a model facility, the methods employed by the RRSP, and three of the expected outcomes of the Model Facility approach. The first expected outcome is to increase compliance with source security guidance materials and national regulations by adding context to those materials, and illustrating their impact on a facility. Second, the effectiveness of each of the tools above is increased by making them part of an integrated system. Third, the methods used to develop the model procedures establishes a sustainable process that can ultimately be transferred to all facilities beyond the model. Overall, the RRSP has utilized the Model Facility approach as an important tool to increase the security of radioactive sources, and to position facilities and countries for the long term secure management of those sources.

Sahid, E J M; Peng, L Y; Siang, C Ch

2013-01-01

Energy is known as one of the essential ingredients for economic development and security of energy supply is crucial in ensuring continuous economic development of a country. Malaysia's proven domestic oil reserves are estimated to last for another 25 years, while that of gas for another 39 years as of 2011. Despite the depleting indigenous energy resources, the primary energy demand has continued to grow robustly, at an annual rate of 6.3 percent per year from 1990 to 2010, while the primary energy import has grown 7.2% per year and the primary energy export has grown at a slower rate of 1.9% per year. This worrying trend is further compounded by the faster rate of primary oil import averaging 10.5% per year while the primary energy export has shrink at a rate of 1.4% per year. This paper has identified two main concerns namely overdependence on fossil fuel and increasing energy import dependency in creating a precarious position towards energy self-sufficiency. The study will analyse the energy security of the country and explore possible options and challenges in enhancing the energy supply security toward sustainable environment.

Energy security, in the 21st century, draws significant attention in most countries worldwide, because the national security and sustainable development depend largely on energy security. The anticipated fossil energy depletion and the instability of their supply drive many countries to consider nuclear energy as their alternative energy source for the enhancement of their national energy security. In this study, indicators measuring the level of energy security in the electric power sector are developed and applied for the assessment of the effectiveness of four electric power system schemes which deploy different nuclear fuel cycle technologies, with consideration for the diversification of the energy markets and the vulnerability to economic disruption. Results show that the contribution of the closed fuel cycle scheme is larger than the once-through fuel cycle scheme in the perspective of energy security. In addition, the completely closed fuel cycle with the spent fuel recycling enhances the national energy security to the maximum extent compared to all other fuel cycle schemes. Since a completely closed fuel cycle is hardly affected by the uranium price changes, this scheme is found to be the most favorable scheme, ensuring the stable profit of utilities and stabilizing the electricity tariff. In addition, the completely closed fuel cycle scheme provides the best enhancement of national energy security with respect to energy supply, under reasonable price conditions. The indicators developed in this study can be utilized as a useful instrument for the measurement of the level of the energy security, especially by the countries importing energy resources for the generation of electric power.

This study proposed an improved Water Poverty Index (WPI) model employed in evaluating Chinese regional water security. Firstly, the Chinese WPI index system was constructed, in which the indicators were obtained according to China River reality. A new mathematical model was then established for WPI values calculation on the basis of Center for Ecology and Hydrology (CEH) model. Furthermore, this new model was applied in Shiyanghe River (located in western China). It turned out that the Chinese index system could clearly reflect the indicators threatening security of river water and the Chinese WPI model is feasible. This work has also developed a Water Security Degree (WSD) standard which is able to be regarded as a scientific basis for further water resources utilization and water security warning mechanism formulation.

This study aims to explore whether a short-term and attachment-based video-feedback intervention, the Video-Feedback Intervention to Promote Positive Parenting With Discussions on the Representational Level (VIPP-R; F. Juffer, M.J. Bakermans-Kranenburg, & M.H. van IJzendoorn, 2008), might be effective in enhancing maternal sensitivity and in promoting infants' attachment security in an Italian sample of dyads with primiparous mothers. Moreover, we explore whether the effectiveness of VIPP-R might be different for parents with insecure attachment representations who might be most in need of preventive intervention, as compared to parents who already have a more balanced and secure state of mind. Thirty-two infants (40% female) and their mothers participated in the study. The sample was divided into an intervention group (n = 16) and a comparison group (n = 16). At 6 and 13 months of age, the Adult Attachment Interview (AAI; M. Main, N. Kaplan, & J. Cassidy, 1985) was administered. Moreover, a 30-min mother-infant play situation was videotaped and coded for maternal sensitivity with the Emotional Availability Scales (Z. Biringen, J. Robinson, & R.N. Emde, 2000). At 13 months of age, the Strange Situation Procedure (M.D.S. Ainsworth, M.D. Blehar, E. Waters, & S. Wall, 1978) was used to assess the security of mother-infant attachment. Results revealed a significant interaction effect between intervention and AAI security for infant attachment security; moreover, main effects of AAI security and intervention for maternal sensitivity were found. The VIPP-R appears effective in enhancing maternal sensitivity and infant attachment security, although only mothers with an insecure attachment representation may benefit from the intervention. © 2014 Michigan Association for Infant Mental Health.

As a new technique for authentication and key generation, physically unclonable function (PUF) has attracted considerable attentions, with extensive research results achieved already. To resist the popular machine learning modeling attacks, a framework to enhance the security of PUFs is proposed. The basic idea is to combine PUFs with a chaotic system of which the response is highly sensitive to initial conditions. For this framework, a specific construction which combines the common arbiter PUF circuit, a converter, and the Chua's circuit is given to implement a more secure PUF. Simulation experiments are presented to further validate the framework. Finally, some practical suggestions for the framework and specific construction are also discussed.

US Africa Command's Disaster Preparedness Program (DPP), implemented by the Center for Disaster and Humanitarian Assistance Medicine, partnered with US Government agencies and international organizations to promote stability and security on the African continent by engaging with African Partner Nations' (PN) civil and military authorities to improve disaster management capabilities. From 2008 to 2015, DPP conducted disaster preparedness and response programming with 17 PNs. DPP held a series of engagements with each, including workshops, strategic planning, developing preparedness and response plans, tabletop exercises, and prioritizing disaster management capability gaps identified through the engagements. DPP partners collected data for each PN to further capacity building efforts. Thus far, 9 countries have completed military pandemic plans, 10 have developed national pandemic influenza plans, 9 have developed military support to civil authorities plans, and 11 have developed disaster management strategic work plans. There have been 20 national exercises conducted since 2009. DPP was cited as key in implementation of Ebola response plans in PNs, facilitated development of disaster management agencies in DPP PNs, and trained nearly 800 individuals. DPP enhanced PNs' ability to prepare and respond to crises, fostering relationships between international agencies, and improving civil-military coordination through both national and regional capacity building.

Younsung Choi

Full Text Available With the rapid development of personal information and wireless communication technology, user authentication schemes have been crucial to ensure that wireless communications are secure. As such, various authentication schemes with multi-factor authentication have been proposed to improve the security of electronic communications. Multi-factor authentication involves the use of passwords, smart cards, and various biometrics to provide users with the utmost privacy and data protection. Cao and Ge analyzed various authentication schemes and found that Younghwa An's scheme was susceptible to a replay attack where an adversary masquerades as a legal server and a user masquerading attack where user anonymity is not provided, allowing an adversary to execute a password change process by intercepting the user's ID during login. Cao and Ge improved upon Younghwa An's scheme, but various security problems remained. This study demonstrates that Cao and Ge's scheme is susceptible to a biometric recognition error, slow wrong password detection, off-line password attack, user impersonation attack, ID guessing attack, a DoS attack, and that their scheme cannot provide session key agreement. Then, to address all weaknesses identified in Cao and Ge's scheme, this study proposes a security enhanced multi-factor biometric authentication scheme and provides a security analysis and formal analysis using Burrows-Abadi-Needham logic. Finally, the efficiency analysis reveals that the proposed scheme can protect against several possible types of attacks with only a slightly high computational cost.

Filimonova, L. A.; Skvortsova, N. K.

2017-11-01

The article examines the problematic aspects of assessing the investment attractiveness of a region associated with the consideration of methodological issues that require refinement from the point of view of its technospheric security. Such issues include the formation of a sound system of indicators for the assessment of man-made risk which has a particular impact on the level of investment attractiveness of the region. In the context of the instability of the economic situation in Russia, the problem of man-made risks assessing in the context of the regional investment attractiveness based on an integrated approach and taking into account such principles as flexibility, adaptability, innovative orientation has not only lost its relevance but was also transformed into one of the most important conditions for ensuring the effective management of all spheres of the regional activities. The article poses the classical problem of making decisions on the results of the assessment of the investment attractiveness of the region in a matrix format evaluating the utility function. The authors of the article recommended a universal risk assessment model with its subsequent synthesis into technospheric security for the comprehensive assessment of regional investment attractiveness. The principal distinguishing feature of the study results are the schemes for manipulation in the evaluation activity associated with the selection of the optimality criteria groups and models for their study. These iterations make it possible to substantiate the choice of the solution for preserving the technospheric security of the region, a field of compromises or an “ideal” solution to the problem of the regional investment attractiveness loss.

Regional energy resource development and energy security under CO2 emission constraint in the greater Mekong sub-region countries (GMS)

International Nuclear Information System (INIS)

Watcharejyothin, Mayurachat; Shrestha, Ram M.

2009-01-01

The paper evaluates effects of energy resource development within the Greater Mekong Sub-region (GMS) on energy supply mix, energy system cost, energy security and environment during 2000-2035. A MARKAL-based integrated energy system model of the five GMS countries was developed to examine benefits of regional energy resource development for meeting the energy demand of these countries. The study found that an unrestricted energy resource development and trade within the region would reduce the total-regional energy systems cost by 18% and would abate the total CO 2 emission by 5% as compared to the base case. All the five countries except Myanmar would benefit from the expansion of regional energy resource integration in terms of lower energy systems costs and better environmental qualities. An imposition of CO 2 emission reduction constraint by 5% on each of the study countries from that of the corresponding emissions under the unrestricted energy resource development in the GMS is found to improve energy security, reduce energy import and fossil fuels dependences and increase volume of power trade within the region. The total energy system cost under the joint CO 2 emission reduction strategy would be less costly than that under the individual emission targets set for each country.

Water, energy, and food are the most important and fundamental resources for human beings and society. Demands for these resources are escalating rapidly because of increases in populations and changes in lifestyles. Therefore intensive demand for those resources makes conflicts between resources. Securities of water, energy, and food are treated separately, however they should be considered as one integrated matter, because water-energy-food are connected and it makes nexus and tradeoff. Security in terms of self-production, diversity of alternatives, and variability are evaluated for water, energy and food for thirty two countries in the Asia-Pacific region. The water and energy nexus includes water consumption for the cooling of power plant systems, water use for hydro power generation, and energy consumption for water allocation and pumping. The water and food nexus consists of water consumption for agriculture and aquaculture. The energy and food nexus includes energy consumption for food production and biomass for energy. Analyses of 11 countries within the Asia- Pacific region show that energy consumption for fish is the largest among foods in Japan, Philippines, and Peru, while energy consumption for cereals is the largest among foods in Canada, US, Indonesia, and others. Water consumption for different types of food and energy are also analyzed, including nexus ratio to total water consumption. The water-energy-food nexus at a local level in the Asia Pacific region are examined by the Research Institute for Humanity and Nature project "Human environmental security in Asia Pacific Ring of Fire". Themes including geothermal power plants for energy development and hot springs as water, shale gas for energy development and water consumption/contamination, aquaculture for food and water contamination are used to evaluate the water-energy-food nexus in the Asia-Pacific region.

In this paper, we are going to outline our efforts and experiences at implementing physical protection education. KINAC (as the only designated educational institute) places great effort in delivering an effective and a high-quality education program for physical protection. We have also provided a way for nuclear operators to share the lessons they have gained through their own experiences. We made physical protection education an important communication channel, not only among nuclear operators but also between operators and a regulatory body. There is growing attention given to education and training on the subject of physical protection in order to enhance the nuclear security culture. The IAEA recommends that all personnel in organizations directly involved with the nuclear industry receive regularly education in physical protection according to the recently revised INFCIRC/225/Rev.5. The Korea Institute of Nuclear Nonproliferation and Control (KINAC) and the Nuclear Safety and Security Commission (NSSC), which are mainly responsible for the national nuclear security regime, have already recognized the importance of education and training in physical protection. The NSSC enacted its decree on physical protection education and training in 2010. KINAC was designated as the first educational institute in 2011 and implemented physical protection education as mandatory from 2012.

Ecological security is close related to the people's survival and development. In the context of the global warming, with the increasingly frequent human activities, ecological and environmental problems have become increasingly prominent. Ecological security has aroused widespread concern, especially in the arid region. It has an important role in national security as well as political security, military security, economic security, social security. Taken Xinjiang as the research area, which is a typical arid region in China, this study establishes an ecological safety assessment indicator system from perspective of the generic process and the formation mechanism of the ecosystem. The framework is based on natural resources dimensions, natural environment dimensions and human disturbance dimensions. Water is the restrictive factor for the development of arid region, so the water resources carrying capacity is the main natural resource of the study area. The natural environment includes SPI(standardized precipitation index), dryness index, landscape vulnerability, NDVI. Human disturbance includes urbanization rate, population density, afforestation area, per capita GDP, water-saving irrigation area, fertilizer and pesticide application, agriculture Mechanical power, energy consumption. The expert scoring method and the coefficient of variation method are used to determine the weight of each indicator, and finally a comprehensive index is constructed to evaluate the ecological security of Xinjiang, that is, the ecological security index. The results indicate that the ecological security of Xinjiang is 0.43, which is in the critical area. The ecological security of Hami, Turpan and Karamay is the lowest, and the ecological security of the Arabian and Yili is the highest. The ecological security of the south in the Xinjiang is higher than that in the north. In short, ecological environment of Xinjiang is in a sensitive period. Effective ecological protection policy

Model, Characterization, and Analysis of Steady-State Security Region in AC/DC Power System with a Large Amount of Renewable Energy

Directory of Open Access Journals (Sweden)

Zhong Chen

2017-08-01

Full Text Available A conventional steady-state power flow security check only implements point-by-point assessment, which cannot provide a security margin for system operation. The concept of a steady-state security region is proposed to effectively tackle this problem. Considering that the commissioning of the increasing number of HVDC (High Voltage Direct Current and the fluctuation of renewable energy have significantly affected the operation and control of a conventional AC system, the definition of the steady-state security region of the AC/DC power system is proposed in this paper based on the AC/DC power flow calculation model including LCC/VSC (Line Commutated Converter/Voltage Sourced Converter-HVDC transmission and various AC/DC constraints, and hence the application of the security region is extended. In order to ensure that the proposed security region can accurately provide global security information of the power system under the fluctuations of renewable energy, this paper presents four methods (i.e., a screening method of effective boundary surfaces, a fitting method of boundary surfaces, a safety judging method, and a calculation method of distances and corrected distance between the steady-state operating point and the effective boundary surfaces based on the relation analysis between the steady-state security region geometry and constraints. Also, the physical meaning and probability analysis of the corrected distance are presented. Finally, a case study is demonstrated to test the feasibility of the proposed methods.

The Importance of the Study of Cognitive Performance Enhancement for U.S. National Security.

Malish, Richard G

2017-08-01

The American military is embarking on the 'Third Offset'-a strategy designed to produce seismic shifts in the future of warfare. Central to the approach is the conjoining of humans, technology, and machines to deliver a decisive advantage on the battlefield. Because technology will spread rapidly and globally, tactical overmatch will occur when American operators possess a competitive edge in cognition. Investigation of cognitive enhancing therapeutics is not widely articulated as an adjunct to the Third Offset, yet failure to study promising agents could represent a strategic vulnerability. Because of its legacy of research into therapeutic agents to enhance human-machine interplay, the aerospace medical community represents a front-running candidate to perform this work. Notably, there are strong signals emanating from gambling, academic, and video-gaming enterprises that already-developed stimulants and other agents provide cognitive benefits. These agents should be studied not only for reasons of national security, but also because cognitive enhancement may be a necessary step in the evolution of humankind. To illustrate these points, this article will assert that: 1) the need to preserve and enhance physical and cognitive health will become more and more important over the next century; 2) aeromedical specialists are in a position to take the lead in the endeavor to enhance cognition; 3) signals of enhancement of the type useful to both military and medical efforts exist aplenty in today's society; and 4) the aeromedical community should approach human enhancement research deliberately but carefully.Malish RG.

ESS-FH: Enhanced Security Scheme for Fast Handover in Hierarchical Mobile IPv6

Science.gov (United States)

You, Ilsun; Lee, Jong-Hyouk; Sakurai, Kouichi; Hori, Yoshiaki

Fast Handover for Hierarchical Mobile IPv6 (F-HMIPv6) that combines advantages of Fast Handover for Mobile IPv6 (FMIPv6) and Hierarchical Mobile IPv6 (HMIPv6) achieves the superior performance in terms of handover latency and signaling overhead compared with previously developed mobility protocols. However, without being secured, F-HMIPv6 is vulnerable to various security threats. In 2007, Kang and Park proposed a security scheme, which is seamlessly integrated into F-HMIPv6. In this paper, we reveal that Kang-Park's scheme cannot defend against the Denial of Service (DoS) and redirect attacks while largely relying on the group key. Then, we propose an Enhanced Security Scheme for F-HMIPv6 (ESS-FH) that achieves the strong key exchange and the key independence as well as addresses the weaknesses of Kang-Park's scheme. More importantly, it enables fast handover between different MAP domains. The proposed scheme is formally verified based on BAN-logic, and its handover latency is analyzed and compared with that of Kang-Park's scheme.

Validity of information security policy models

Joshua Onome Imoniana

Full Text Available Validity is concerned with establishing evidence for the use of a method to be used with a particular set of population. Thus, when we address the issue of application of security policy models, we are concerned with the implementation of a certain policy, taking into consideration the standards required, through attribution of scores to every item in the research instrument. En today's globalized economic scenarios, the implementation of information security policy, in an information technology environment, is a condition sine qua non for the strategic management process of any organization. Regarding this topic, various studies present evidences that, the responsibility for maintaining a policy rests primarily with the Chief Security Officer. The Chief Security Officer, in doing so, strives to enhance the updating of technologies, in order to meet all-inclusive business continuity planning policies. Therefore, for such policy to be effective, it has to be entirely embraced by the Chief Executive Officer. This study was developed with the purpose of validating specific theoretical models, whose designs were based on literature review, by sampling 10 of the Automobile Industries located in the ABC region of Metropolitan São Paulo City. This sampling was based on the representativeness of such industries, particularly with regards to each one's implementation of information technology in the region. The current study concludes, presenting evidence of the discriminating validity of four key dimensions of the security policy, being such: the Physical Security, the Logical Access Security, the Administrative Security, and the Legal & Environmental Security. On analyzing the Alpha of Crombach structure of these security items, results not only attest that the capacity of those industries to implement security policies is indisputable, but also, the items involved, homogeneously correlate to each other.

Regional energy resource development and energy security under CO{sub 2} emission constraint in the greater Mekong sub-region countries (GMS)

Energy Technology Data Exchange (ETDEWEB)

Watcharejyothin, Mayurachat; Shrestha, Ram M. [School of Environment, Resources and Development, Asian Institute of Technology (Thailand)

2009-11-15

The paper evaluates effects of energy resource development within the Greater Mekong Sub-region (GMS) on energy supply mix, energy system cost, energy security and environment during 2000-2035. A MARKAL-based integrated energy system model of the five GMS countries was developed to examine benefits of regional energy resource development for meeting the energy demand of these countries. The study found that an unrestricted energy resource development and trade within the region would reduce the total-regional energy systems cost by 18% and would abate the total CO{sub 2} emission by 5% as compared to the base case. All the five countries except Myanmar would benefit from the expansion of regional energy resource integration in terms of lower energy systems costs and better environmental qualities. An imposition of CO{sub 2} emission reduction constraint by 5% on each of the study countries from that of the corresponding emissions under the unrestricted energy resource development in the GMS is found to improve energy security, reduce energy import and fossil fuels dependences and increase volume of power trade within the region. The total energy system cost under the joint CO{sub 2} emission reduction strategy would be less costly than that under the individual emission targets set for each country. (author)

A Fast Enhanced Secure Image Chaotic Cryptosystem Based on Hybrid Chaotic Magic Transform

Srinivas Koppu

2017-01-01

Full Text Available An enhanced secure image chaotic cryptosystem has been proposed based on hybrid CMT-Lanczos algorithm. We have achieved fast encryption and decryption along with privacy of images. The pseudorandom generator has been used along with Lanczos algorithm to generate root characteristics and eigenvectors. Using hybrid CMT image, pixels are shuffled to accomplish excellent randomness. Compared with existing methods, the proposed method had more robustness to various attacks: brute-force attack, known cipher plaintext, chosen-plaintext, security key space, key sensitivity, correlation analysis and information entropy, and differential attacks. Simulation results show that the proposed methods give better result in protecting images with low-time complexity.

Latin American and the Caribbean (LAC) is a water and land abundant region, and plays a key role in meeting global food and water security. During the last decade, LAC has experience a rapid socio-economic growth, largely sustained by its competitive advantage in the production and exports of agricultural and mining products and by the high commodity prices in the global market. This study seeks to quantify the contribution of LAC's agriculture to global food and water security, i.e. virtual water trade, and evaluate the environmental and societal implications for regional development. Results show that between 2000 and 2011, LAC has increase its agricultural production 27%, and it now accounts for nearly 18% of the global agricultural market. As a result, the agricultural water footprint (WF) of LAC was augmented 65%; and yet, nearly 19% to 44% of the actual agricultural WF - depending on the countries - is virtual water exported to third countries. In fact, almost 50% of the increase in global virtual water trade during the last decade, corresponds to LAC. Such global contribution has significant implications for regional water and food security. From an environmental perspective, crop expansion (mostly rain-fed) resulted in the deforestation of nearly 1 million km2, turning this region into the second most important deforestation hotspots worldwide. This land clearing is having large impacts of ecosystem services, e.g. carbon sequestration, water quality or biodiversity conservation. From a socio-economic perspective, increasing agricultural production has improved regional food security indicators, although one every seven children is still stunted in LAC and nearly 10% of the population remains undernourished. Dietary shifts and socio-cultural factors also lag behind the growing problem of malnutrition in the region, i.e. overweight and obesity. Improvements of water access and sanitation, have had a positive impact on food security indicators, especially

Smart environments established by the development of mobile technology have brought vast benefits to human being. However, authentication mechanisms on portable smart devices, particularly conventional biometric based approaches, still remain security and privacy concerns. These traditional systems are mostly based on pattern recognition and machine learning algorithms, wherein original biometric templates or extracted features are stored under unconcealed form for performing matching with a new biometric sample in the authentication phase. In this paper, we propose a novel gait based authentication using biometric cryptosystem to enhance the system security and user privacy on the smart phone. Extracted gait features are merely used to biometrically encrypt a cryptographic key which is acted as the authentication factor. Gait signals are acquired by using an inertial sensor named accelerometer in the mobile device and error correcting codes are adopted to deal with the natural variation of gait measurements. We evaluate our proposed system on a dataset consisting of gait samples of 34 volunteers. We achieved the lowest false acceptance rate (FAR) and false rejection rate (FRR) of 3.92% and 11.76%, respectively, in terms of key length of 50 bits.

Full Text Available The article deals with the urgent problem concerning the regional development as well as the specific organization, or to the development of an integrated system of economic security of the organization. The article discusses the importance of such an element of economic security (including the financial security as the accounting and control as well as their possible violations. The authors substantiate their position on the relationship of the violations of accounting and control and also the internal theft, other economic crimes and their negative consequences. The analysis of the existing national and foreign sources related to the subject of the study is carried out. The conclusion is made about the lack of modern research devoted to the study of the protective properties of accounting, control and their violations, which condition economic crimes. The methodological tools of the research include dialectic method, systemic analysis, complex sociological methods: the analysis of the legal sources, of statistical information and judicial practice. On the basis of the analysis of criminal cases, financial statements, publications media, the authors made the conclusion about the conditionality of the theft in the organizations as there are the violations of accounting and control, low efficiency of control and auditing, of preventive measures for neutralization of the violations of accounting and control from the services of economic security, accounting offices, auditing and law enforcement services. The recommendations for the optimization of this work are introduced. They can be used by accounting departments, auditing bodies, fiscal authorities at the municipal and regional level and by law enforcement officials. The economic security is necessary for any organizations regardless of their forms of ownership, ranging from government organizations to small kiosks. The difference will only consist in the means and methods.

And the question is now how to handle this delicate situation in a strategically and geopolitically important region. So by controlling Georgia (in case Russia reaches abovementioned aims, Russia actually will be able to cut off Central Asia and Caspian resources. It means Russia would be able to isolate and cut off Azerbaijan and Central Asian countries and it will significantly strengthen its energy monopoly over Europe with all results coming out from that fact. So it’s about major shift in the energy policy and major shift in geopolitics based on this energy policy and Russian energy monopoly. The August war in Georgia demonstrated some risks associated with the functioning of the transit energy corridor in the southern Caucasus. It also demonstrated the need for broader security guarantees for a region that is vital to European and global energy security. Paper deals with economic damage inflicted by the Russo-Georgian war in South Caucasus and its implications for regional security.

Novel Approaches to Enhance Mobile WiMAX Security

Full Text Available The IEEE 802.16 Working Group on Broadband Wireless Access Standards released IEEE 802.16-2004 which is a standardized technology for supporting broadband and wireless communication with fixed and nomadic access. After the IEEE 802.16-2004 standard, a new advanced and revised standard was released as the IEEE 802.16e-2005 amendment which is foundation of Mobile WiMAX network supporting handover and roaming capabilities. In the area of security aspects, compared to IEEE 802.16-2004, IEEE 802.16e, called Mobile WiMAX, adopts improved security architecture—PKMv2 which includes EAP authentication, AES-based authenticated encryption, and CMAC or HMAC message protection. However, there is no guarantee that PKMv2-based Mobile WiMAX network will not have security flaws. In this paper, we investigate the current Mobile WiMAX security architecture focusing mainly on pointing out new security vulnerabilities such as a disclosure of security context in network entry, a lack of secure communication in network domain, and a necessity of efficient handover supporting mutual authentication. Based on the investigation results, we propose a novel Mobile WiMAX security architecture, called RObust and Secure MobilE WiMAX (ROSMEX, to prevent the new security vulnerabilities.

The four LHC experiments rely on experiment specific services running on machines mainly located at CERN. Some of these services have been rated by the experiments as very critical: any loss or degradation of performance has a major impact on the experiment's production and analysis activities. It is therefore important to provide a reliable and robust operational environment. In this work we describe the strategy based on service deployment, security and virtualization adopted to enhance the reliability of ATLAS and CMS central services.

An enhanced performance through agent-based secure approach for mobile ad hoc networks

Science.gov (United States)

Bisen, Dhananjay; Sharma, Sanjeev

2018-01-01

This paper proposes an agent-based secure enhanced performance approach (AB-SEP) for mobile ad hoc network. In this approach, agent nodes are selected through optimal node reliability as a factor. This factor is calculated on the basis of node performance features such as degree difference, normalised distance value, energy level, mobility and optimal hello interval of node. After selection of agent nodes, a procedure of malicious behaviour detection is performed using fuzzy-based secure architecture (FBSA). To evaluate the performance of the proposed approach, comparative analysis is done with conventional schemes using performance parameters such as packet delivery ratio, throughput, total packet forwarding, network overhead, end-to-end delay and percentage of malicious detection.

Rice, Mark J.; Bonebrake, Christopher A.; Dayley, Greg K.; Becker, Larry J.

2017-06-30

Inter-Control Center Communications Protocol (ICCP), defined by the IEC 60870-6 TASE.2 standard, was developed to enable data exchange over wide area networks between electric system entities, including utility control centers, Independent System Operators (ISOs), Regional Transmission Operators (RTOs) and Independent Power Producers (IPP) also known as Non-Utility Generators (NUG). ICCP is an unprotected protocol, and as a result is vulnerable to such actions as integrity violation, interception or alteration, spoofing, and eavesdropping. Because of these vulnerabilities with unprotected ICCP communication, security enhancements, referred to as Secure ICCP, have been added and are included in the ICCP products that utilities have received since 2003 when the standard was defined. This has resulted in an ICCP product whose communication can be encrypted and authenticated to address these vulnerabilities.

Economic Evaluation of the Information Security Levels Achieved by Electric Energy Providers in North Arctic Region

Sushko, O. P.; Kaznin, A. A.; Babkin, A. V.; Bogdanov, D. A.

2017-10-01

The study we are conducting involves the analysis of information security levels achieved by energy providers operating in the North Arctic Region. We look into whether the energy providers’ current information security levels meet reliability standards and determine what further actions may be needed for upgrading information security in the context of the digital transformation that the world community is undergoing. When developing the information security systems for electric energy providers or selecting the protection means for them, we are governed by the fact that the assets to be protected are process technologies. While information security risk can be assessed using different methods, the evaluation of the economic damage from these risks appears to be a difficult task. The most probable and harmful risks we have identified when evaluating the electric energy providers’ information security will be used by us as variables. To provide the evaluation, it is necessary to calculate the costs relating to elimination of the risks identified. The final stage of the study will involve the development of an operation algorithm for the North Arctic Region’s energy provider’s business information protection security system - a set of information security services, and security software and hardware.

Unattended systems with remote transmission capabilities (RM) have the potential to improve safeguards efficiency. Moreover, the evolution of technology and the steady growing of nuclear materials subject to control, lead modern safeguards increasingly utilizing unattended equipment with the capability to store relevant data for long periods of time coupled with the option of being remotely accessed and checked. Remote inspection is still a concept under development, but it may end to be a powerful more efficient verification modality in medium term future. An important part of drawing meaningful safeguards conclusions rests on authenticity and reliability of the information on nuclear material and facilities acquired through the various verification activities and measures applied by IAEA and regional safeguards organizations, like ABACC. The increasing utilization of such technology to further optimize safeguards responds to a multifaceted environment where security of information for all relevant parties is of utmost importance. From the point of view of the IAEA and ABACC, the use of any technology for safeguards application, and specially the use of RM, requires to ensure the security of data collected to guarantee the validity and veracity of such information throughout the whole process (e.g., from collecting to reviewing). This is also valid to the SSAC involved in the process. Information security is also relevant for States and Operators. Assurance should be given that the information could not be withdrawn by non-authorized entities and that facility data is also fully secured. Another important aspect related to RM that may also fall in the security aspect of safeguards relevant information that merits further consideration, is the sharing of information between organizations like ABACC and the IAEA as well as the possibility to make this data available for States authorities purposes. This paper discusses three main themes related to RM: (i) the extent

The advent of the nuclear renaissance gives rise to a concern for the effective design of nuclear fuel cycle systems that are safe, secure, nonproliferating and cost-effective. We propose to integrate the monitoring of the four major factors of nuclear facilities by focusing on the interactions between Safeguards, Operations, Security, and Safety (SOSS). We proposed to develop a framework that monitors process information continuously and can demonstrate the ability to enhance safety, operations, security, and safeguards by measuring and reducing relevant SOSS risks, thus ensuring the safe and legitimate use of the nuclear fuel cycle facility. A real-time comparison between expected and observed operations provides the foundation for the calculation of SOSS risk. The automation of new nuclear facilities requiring minimal manual operation provides an opportunity to utilize the abundance of process information for monitoring SOSS risk. A framework that monitors process information continuously can lead to greater transparency of nuclear fuel cycle activities and can demonstrate the ability to enhance the safety, operations, security and safeguards associated with the functioning of the nuclear fuel cycle facility. Sandia National Laboratories (SNL) has developed a risk algorithm for safeguards and is in the process of demonstrating the ability to monitor operational signals in real-time though a cooperative research project with the Japan Atomic Energy Agency (JAEA). The risk algorithms for safety, operations and security are under development. The next stage of this work will be to integrate the four algorithms into a single framework

Nuclear security: strategies and techniques

The modern society, whether in developed or in developing countries, depend on the availability of nuclear energy and on the day-to-day use of radioactive materials in medicine, agriculture, industry and for research. Before 9/11, these activities were mainly covered by safety rules regarding health and environment. Since 9/ 11, it is clear, that these activities also require adequate security. For the continued and expanded use of nuclear energy or radioactive materials, nuclear security is indispensable and an important prerequisite for successful and sustainable development. Many of our nuclear security services, expert assistance and training events, we have assisted Member States in their efforts to improve their preparedness and response capabilities and acquired a much better understanding of Member States prob and the need for further support. The end of the Cold War was marked by a shift from a bi-polar structure of global security into a more complex and unpredictable configuration of world affairs. It also brought about new security challenges, i.e. an increased probability for low-density regional, national or sub-national conflicts with new and more dispersed threats emanating from a larger number of actors, including non-state actors; terrorists or criminals. The audio-visual impact of modern media has enhanced the socio-psychological impact on a global scale of such conflicts. The number of cases of illicit trafficking in nuclear materials that were recorded since the 90's raised concern about the international physical protection regime and triggered an effort to enhance our capabilities for prevention, detection and responses regarding terrorist acts, as well as to strengthen the Convention on the Physical Protection of Nuclear Material

The economy of the Murmansk region in Russia is based on energy intensive industry, mainly metallurgies, and consequently, the region is highly dependant on the ageing Kola nuclear power plant. This interdependence together with other weaknesses in the regional energy system creates threats to the energy supply security of the region. This paper analyses the internal and external threats influencing the region and presents potential solutions. Scenarios further illustrate possible future paths these potential solutions could deliver by the year 2025

Problems related to food security in Russian Arctic (dietary imbalance, predominance of carbohydrates, shortage of milk products, vegetables and fruits, deficit of vitamins and microelements, chemical, infectious and parasitic food contamination) have been defined in the literature. But no standard protocol of food security assessment has been used in the majority of studies. Our aim was to obtain food security indicators, identified within an Arctic collaboration, for selected regions of the Russian Arctic, Siberia and the Far East, and to compare food safety in these territories. In 18 regions of the Russian Arctic, Siberia and the Far East, the following indicators of food security were analyzed: food costs, food consumption, and chemical and biological food contamination for the period 2000-2011. Food costs in the regions are high, comprising 23-43% of household income. Only 4 out of 10 food groups (fish products, cereals, sugar, plant oil) are consumed in sufficient amounts. The consumption of milk products, eggs, vegetables, potatoes, fruits (and berries) is severely low in a majority of the selected regions. There are high levels of biological contamination of food in many regions. The biological and chemical contamination situation is alarming, especially in Chukotka. Only 7 food pollutants are under regular control; among pesticides, only DDT. Evenki AO and Magadan Oblast have reached peak values in food contaminants compared with other regions. Mercury in local fish has not been analyzed in the majority of the regions. In 3 regions, no monitoring of DDT occurs. Aflatoxins have not been analyzed in 5 regions. Nitrates had the highest percentage in excess of the hygienic threshold in all regions. Excesses of other pollutants in different regions were episodic and as a rule not high. Improvement of the food supply and food accessibility in the regions of the Russian Arctic, Siberia and the Far East is of utmost importance. Both quantitative and qualitative

Public assessment of new surveillance-oriented security technologies: Beyond the trade-off between privacy and security.

Science.gov (United States)

Pavone, Vincenzo; Esposti, Sara Degli

2012-07-01

As surveillance-oriented security technologies (SOSTs) are considered security enhancing but also privacy infringing, citizens are expected to trade part of their privacy for higher security. Drawing from the PRISE project, this study casts some light on how citizens actually assess SOSTs through a combined analysis of focus groups and survey data. First, the outcomes suggest that people did not assess SOSTs in abstract terms but in relation to the specific institutional and social context of implementation. Second, from this embedded viewpoint, citizens either expressed concern about government's surveillance intentions and considered SOSTs mainly as privacy infringing, or trusted political institutions and believed that SOSTs effectively enhanced their security. None of them, however, seemed to trade privacy for security because concerned citizens saw their privacy being infringed without having their security enhanced, whilst trusting citizens saw their security being increased without their privacy being affected.

G8 Regional Security Governance through Sanctions and Force

Directory of Open Access Journals (Sweden)

John Kirton

2014-11-01

Full Text Available Why do the Group of Eight (G8 members approve its members’ use of material sanctions in some regional conflicts but military force in others?2 As an informal security institution composed of major democratic powers from North America, Europe and Asia, the G8 has often chosen sanctions, notably on Iran in 1980, Afghanistan in 1980, Sudan in 2004, North Korea in 2006, and Syria in 2011. It has increasingly chosen military force, notably in Iraq in 1990, Kosovo in 1999, the USSR over Afghanistan in 2001, Libya in 2011, and Mali in 2013. Yet the G8’s choice, initiation, commitment, compliance, implementation and effectiveness of both sanctions and force has varied. Force was chosen and used effectively only in the post cold war period, primarily where the target was close to southern Europe. A high relative-capability predominance of G8 members over the target country strongly produces the G8’s choice of force, but a high, direct, deadly threat from the target state to G8 countries does not. Geographic proximity and the connectivity coming from the former colonial relationship between G8 members and the target country only weakly cause the G8 to choose force. Support from the most relevant regional organization – the North Atlantic Treaty Organization – and support from the United Nations in the form of an authorizing UN Security Council or General Assembly resolution have a strong, positive effect on the G8’s choice of force. Accompanying accountability mechanisms from the G8 itself have a variable impact, as leaders’ iteration of the issue at subsequent summits does not increase compliance with G8 commitments on force-related cases, but their foreign ministers’ follow up does to a substantial degree.

A security-enhanced chaos communication scheme with time delay signature (TDS) suppression and phase-encrypted feedback light is proposed, in virtue of dual-loop feedback with independent high-speed phase modulation. We numerically investigate the property of TDS suppression in the intensity and phase space and quantitatively discuss security of the proposed system by calculating the bit error rate of eavesdroppers who try to crack the system by directly filtering the detected signal or by using a similar semiconductor laser to synchronize the link signal and extract the data. The results show that TDS embedded in the chaotic carrier can be well suppressed by properly setting the modulation frequency, which can keep the time delay a secret from the eavesdropper. Moreover, because the feedback light is encrypted, without the accurate time delay and key, the eavesdropper cannot reconstruct the symmetric operation conditions and decode the correct data.

It should be emphasized that the fundamental shift has taken place in international relations, away from a world dominated by the bipolar super-Power confrontation. There is a today to be more concerned about regional instabilities, which are made more threatening by the potential proliferation of weapons of mass destruction. Just as every nation was affected by the cold war, regional instabilities and proliferation concern each member of the world community. In the Asia-Pacific region, the goal is clear: safer, more stable military postures; transparency and confidence-building; and stronger non-proliferation norms. In working together towards that goal, there is a need to foster greater security through bilateral and multilateral dialogue. In that way, one could promote the change within and among societies; that is the best hope for defusing regional tensions, preventing the spread of weapons of mass destruction, and building a lasting peace

Shrestha, B. R.

2012-12-01

Earth observations bear special significance in the Himalayan Region owing to the fact that routine data collections are often hampered by highly inaccessible terrain and harsh climatic conditions. The ongoing rapid environmental changes have further emphasized its relevance and use for informed decision-making. The International Center for Integrated Mountain Development (ICIMOD), with a regional mandate is promoting the use of earth observations in line with the GEOSS societal benefit areas. ICIMOD has a proven track record to utilize earth observations notably in the areas of understanding glaciers and snow dynamics, disaster risk preparedness and emergency response, carbon estimation for community forestry user groups, land cover change assessment, agriculture monitoring and food security analysis among others. This paper presents the challenges and lessons learned as a part of capacity building of ICIMOD to utilize earth observations with the primary objectives to empower its member countries and foster regional cooperation. As a part of capacity building, ICIMOD continues to make its efforts to augment as a regional resource center on earth observation and geospatial applications for sustainable mountain development. Capacity building possesses multitude of challenges in the region: the complex geo-political reality with differentiated capacities of member states, poorer institutional and technical infrastructure; addressing the needs for multiple user and target groups; integration with different thematic disciplines; and high resources intensity and sustainability. A capacity building framework was developed based on detailed needs assessment with a regional approach and strategy to enhance capability of ICIMOD and its network of national partners. A specialized one-week training course and curriculum have been designed for different thematic areas to impart knowledge and skills that include development practitioners, professionals, researchers and

Pipelines are efficient, highly reliable and safe means of transportation. However, despite intensive right of way surveillance by foot, car and out of the air, pipeline leaks and illegal tappings are a reality - sometimes with catastrophic results. These events show a gap in real-time monitoring caused by the highly distributed nature of pipelines. Parts of this gap now can be closed with distributed fiber optic sensing technology. Using various physical effects this technology is apt to detect temperature, strain, vibrations and sound with very good localization over spans up to 50 km with a single sensor cable. Various field tested applications like leakage detection, third party activity monitoring and intrusion detection or ground movement detection as well as integrity monitoring proof that distributed fiber optic sensing can enhance pipeline safety and security.

As well, Morocco has developed a new law on radiological and nuclear safety and security which was promulgated in 2014. Some Moroccan universities in cooperation with the IAEA-International Nuclear Security Education Network (INSEN) and the US-DoS Partnership for Nuclear Security (PNS) are working to develop their nuclear security educational programmes. In this regard, faculties who have been involved in INSEN Professional Development Courses (PDCs) have acquired a high-quality of knowledge and teaching tools in nuclear security topics that led them to be able to develop and teach their nuclear security curriculum as is the case at the University of Ibn Tofail. Furthermore, University of Ibn Tofail has developed in 2014 with collaboration with CRDFGlobal the first Institute of Nuclear Material Management (INMM) Student Chapter in Africa. This Chapter has organized many events to promote best practices among the young generation. Moreover, University of Ibn Tofail and Brandenburg University in Germany are working to develop a PDC on Nuclear IT/Cyber Security to be held in Kenitra, Morocco. This PDC aims at building capacity among the academic communities from Africa and MENA Region in order to further raise awareness, develop and disseminate best practices, increase professional standards and therefore enhance nuclear security culture. So, this paper will present some nuclear security education activities in Morocco and more specifically at the University of Ibn Tofail.

This study aims to provide security solutions for implementing electronic medical records (EMRs). E-Health organizations could utilize the proposed method and implement recommended solutions in medical/health systems. Majority of the required security features of EMRs were noted. The methods used were tested against each of these security features. In implementing the system, the combination that satisfied all of the security features of EMRs was selected. Secure implementation and management of EMRs facilitate the safeguarding of the confidentiality, integrity, and availability of e-health organization systems. Health practitioners, patients, and visitors can use the information system facilities safely and with confidence anytime and anywhere. After critically reviewing security and data transmission methods, a new hybrid method was proposed to be implemented on EMR systems. This method will enhance the robustness, security, and integration of EMR systems. The hybrid of simple object access protocol/extensible markup language (XML) with advanced encryption standard and secure hash algorithm version 1 has achieved the security requirements of an EMR system with the capability of integrating with other systems through the design of XML messages.

A GIS-based decision support system for regional eco-security assessment and its application on the Tibetan Plateau.

Regional eco-security assessment is an intricate, challenging task. In previous studies, the integration of eco-environmental models and geographical information systems (GIS) usually takes two approaches: loose coupling and tight coupling. However, the present study used a full coupling approach to develop a GIS-based regional eco-security assessment decision support system (ESDSS). This was achieved by merging the pressure-state-response (PSR) model and the analytic hierarchy process (AHP) into ArcGIS 9 as a dynamic link library (DLL) using ArcObjects in ArcGIS and Visual Basic for Applications. Such an approach makes it easy to capitalize on the GIS visualization and spatial analysis functions, thereby significantly supporting the dynamic estimation of regional eco-security. A case study is presented for the Tibetan Plateau, known as the world's "third pole" after the Arctic and Antarctic. Results verified the usefulness and feasibility of the developed method. As a useful tool, the ESDSS can also help local managers to make scientifically-based and effective decisions about Tibetan eco-environmental protection and land use. Copyright (c) 2010 Elsevier Ltd.

Comprising 65-70% of the world's oil reserves, the Gulf States (Saudi Arabia, Iran, Iraq, Kuwait, UAE and Qatar) are key countries for the solutions to the energy supply matters of the world. Free flow of oil to the world markets from Gulf region is an indispensable part of the major security issues. The Middle East has had mainly security related problems such as Arab-Israeli wars and conflicts, Arab-Iranian war and conflicts, Arab-Arab war and conflicts, US-Gulf wars and conflicts and more recently radicalism and terrorist attacks. Energy supply security requires the enhancement of the peace and cooperation between countries instead of competition. Preventive policy approaches are more suitable to address energy supply matters. Preventive strategy might be possible with the active participation of NATO within the 'out of area' type operations to the Middle East and quite possibly indirectly to the Asia-Pacific regions. Religious and ethnic radicalism and terrorist attacks has also direct effects over oil supply security matters

Developing countries have experienced crucial conditions in meeting the needs for food, energy, and water security. This paper presents a country-level quantitative assessment of the current issues associated with the Food-Energy-Water-Security (FEWS) Nexus in the Middle East region. In this study, sixteen countries in the Middle East region are chosen, namely, Arabian Peninsula, Iran, Syria, Lebanon, Israel, Palestine, Egypt, and Turkey. The most recent datasets are used to study and analyze the factors that have emerged the demand to understand and manage the linkage of FEW systems in the region. Water scarcity, extreme events, population growth, urbanization, economic growth, poverty, and political stability are found to be the key drivers of the current challenges in the Middle East region. Additionally, the results suggest that these factors have created a subsequent stress on FEW resources specifically on water sector in the region. Therefore, more attention is required to sustain the FEW resources and cope with the socio-economic development.

This paper discusses the results of a questionnaire-based survey used to assess the safety, security and resilience of information and communications technology (ICT) and supervisory control and data acquisition (SCADA) systems used in the Norwegian oil and gas industry. The survey identifies several challenges, including the involvement of professionals with different backgrounds and expertise, lack of common risk perceptions, inadequate testing and integration of ICT and SCADA systems, poor information sharing related to undesirable incidents and lack of resilience in the design of technical systems. Action research is proposed as a process for addressing these challenges in a systematic manner and helping enhance the safety, security and resilience of ICT and SCADA systems used in oil and gas operations.

Full Text Available   Despite economic integration challenges, ASEAN faces greater security challenges. It is obvious to assert that a stable economic development requires a secure regional atmosphere. The most probable threats against ASEAN are ranging from hostile foreign entities infiltration, intra and inter states disputes, radical religious movements, human trafficking, drugs and narcotics smuggling, cybercrimes and environmental disasters. In 2009, ASEAN established the ASEAN Political and Security Community as the umbrella of ASEAN’s political and security initiatives. APSC slots in some significant fora; ASEAN Intergovernmental Commission on Human Rights (AICHR, ASEAN Foreign Ministers Meeting (AMM,  ASEAN Regional Forum (ARF, ASEAN Defense Minister’s Meeting (ADMM, ASEAN Law Ministers Meeting (ALAWMM, and ASEAN Ministerial Meeting on Transnational Crimes (AMMTC. The wide array of these forums signify ASEAN efforts to confront double features of security; the traditional and nontraditional or critical security. The traditional security considers state security as the primary object security. While the critical security tends to focus on non-state aspects such as individual human being as its referent object. Even though some argue that APSC has been able to preserve the stability in the region, it still lack of confidence in solving critical issues such as territorial disputes and irregular migrants problems.Therefore, this piece would examine the fundamental questions: How does ASEAN address beyond state security issues in its security policy through APSC? To search for the answer this paper would apply critical security studies approach. Critical security posits that threats are not always for the states but in many cases for the people. Based on the examination of ASEAN security policies, this paper argues that ASEAN’s security policy has touched the non-traditional security issues but showing slow progress on its development and application.

Full Text Available Import is traditionally considered as a source for saturation of a home market with scarce commodities or goods non-manufactured in an importing country. However, the larger is the share of import in the total volume of deliveries, the greater is the hazard for economic security of the region and for the state upon the whole. The analysis has revealed the fact that in the regional industry there is a real situation of absolute import dependence. It means that enterprises have been functioning only based on import deliveries to manufacture some single components for products of production-technical purposes.

Rice is the major staple food in most Asian countries. However, with rapidly growing populations, sustained high productivity and yields through improving water productivity is critically important. Increasingly complex energy-agriculture relationships require an in-depth understanding of water and energy tradeoffs. This study contributes to energy and food policies by analysing the complex energy, water and economics dynamics across a selection of major rice growing countries. The results show that tradeoffs exist between yield and energy inputs with high yield attributed to higher levels of energy input. The selected developed countries show higher energy productivity, relative to all other energy inputs, compared to the selected developing counties, owing to enhanced mechanisation, on-farm technology and improved farm management. Among all countries, China has the highest water productivity due to water-saving irrigation practices. These practices offer opportunities for developed and developing countries to increase water productivity at the same time taking advantage of economic and energy benefits of reduced pumping. Sustained production from agriculture is vital to food security. Improved irrigation practices can offset environmental footprints in the short run but their large-scale implementation remains an issue. In the long run, investments are needed to buffer the negative impacts of food production on the environment. Investments to boost water productivity and improved energy use efficiency in crop production are two pathways to reduce energy dependency, enhanced natural resource sustainability and ensuring future food security.

Full Text Available The main objective of this article was to determine the level of the Chinese energy security that was built up for last several decades. In order to reach the set aim the author figured the current condition of the energy sector within the leading states of the Asia-Pacific Region and compared it with a similar condition ofChina. The condition’s characteristics included the following: Chinese energy balance, oil production, import and consumption, energy efficiency, CO2 emissions, electricity amount produced by using the renewable energy sources (hydropower, wind energy, sun energy and nuclear energy. In addition the authorities’ plans for the expansion of the mentioned renewable and nuclear energy production were as well discovered. The probable threats of the energy security and possible obstacles for the extensive means of sustaining the country’s energy security were also brought up.Statistical, comparative and analytical methods were applied in the process of the current research. As a result the PRC was found to be at a threshold to energetic crisis. In order to avoid the scenario two innovative methods were proposed as the means of avoiding the possible future crisis and sustaining energy security.The research results can be applied in determining the domestic and foreign policy of China as well as the foreign policies of the PRC’s energetic partners both within the Asia-Pacific Region and beyond its borders. DOI: http://dx.doi.org/10.12731/2218-7405-2013-7-39

Full Text Available The Silk Road Economic Belt and the 21st Century Maritime Silk Road initiatives (“One Belt, One Road” are of significance in enhancing China’s open economy. This article explores the dual security challenges faced by the “One Belt, One Road” initiative. These challenges include both traditional security challenges, such as great power competition, territorial and island disputes, and political turmoil in the region, as well as non-traditional threats such as terrorism, piracy, and transnational organized crime. This article analyzes the present situation of security cooperation in the region covered by “One Belt, One Road” and also suggests that China needs to pay special attention to three issues, namely the supply of public security goods, the interests of the United States and Russia, and the pivot of Pakistan, besides developing its own strength.

Challenges of transfrontier conservation areas: Natural resources nationalism, security and regionalism in the southern African development community region

Full Text Available Transfrontier Conservation Areas (TFCAs initiatives in the Southern African Development Community (SADC region offer hope for providing a mechanism for resolving political tensions and conflicts which are not only related to environmental issues but to security concerns as well. The geopolitical implications of TFCAs in the SADC region cannot be overemphasised with regard to international relations and regional integration. The SADS region is characterised by histories of contested military balance of power and geopolitical rivalries which have a potential to degenerate into military confrontation. Although there is a strong belief in multilateral co-operation among SADC member countries, most of them often engage the international community at the bilateral level. Moreover, there is disharmony in constitutional applications of the rule of law, respect of human rights and good governance. However, TFCAs initiatives in Southern Africa have been seen as offering an opportunity to heal the wounds of pre- and post-independence wars of destabilisation through the encouragement of inter-state collaboration and co-operation by giving governments an opportunity for mutual action on issues of common interest.

Full text: A master’s degree programme in nuclear security and safeguards has been developed and offered at Chulalongkorn University for the first time in 2013 in order to develop necessary human resources in the fields of nuclear security and safeguards who can continue to work, conduct research, or serve as educators in these fields in Thailand and the Southeast Asian region. The first group of 20 students joined the programme in 2013 and recently graduated. The programme was one-of-its-kind, as there have not been many similar specialized programmes in nuclear security and safeguards in the past. In this paper, challenges and lessons learned throughout the programme are reported. Experience from the pilot programme will be used to improve the next round of the programme which is expected to start in 2017. With this program, more nuclear knowledge can be shared and maintained among the Association of South East Asian Nations (ASEAN) countries to ensure the peaceful utilization of nuclear technology in the region.

Energy security and pattern of regional conflicts in Eurasia: From a constructive framework of analysis

Directory of Open Access Journals (Sweden)

Nalin Mohapatra

2018-02-01

Full Text Available The term energy security is undergoing a sea change from a state-centric economic conception to a sociological one. The definitional aspect is undergoing a transformation because of the changing pattern of relations between “energy producing and consuming states” along with “transit states”. Eurasia is one such region where the broader definition of energy security can be applicable. The existence of historically rooted social conflicts like Chechnya, South Ossetia, Crimea, “simmering discontent” in Siberia and Far East, and primordial apprehensions between ethnic groups (Armenian and Azeri in Nagorno Karabakh are providing a structural basis for the accentuation of regional conflicts. Most of these conflicts are taking place in Eurasia due to existence of natural resources like energy. Often competition over controlling transportation corridor is also generating societal tension. Some of these trajectories are putting this geopolitical space into a “cauldron.” Against this backdrop, Constructivism is emerging as a major theoretical approach to study the securitization processes in Eurasia.

A systematic proposal for the driving forces and mechanisms for its implementation is suggested. It is shown that target-oriented approach can be successfully used at the regional level as a mechanism for economic neoindustrialization of an old-industrial region. Conceptual approach to developing comprehensive program of industrial development in the industrial region that implements the ideas of neoindustrialization in relation to industry of Sverdlovsk region is presented. It was found that the regional technology platform can be an effective tool for combining the interests of territorial and sectoral development. It is proved that the idea of neoindustrialization can be realized only as a result of wise industrial policy and road map formation for the movement to an entirely new high-tech based industrial development. In the process of forming, the problem of neoindustrialization of a «pure» market as a factor in increasing the economic security is actualized.

Gill, Sarvajeet Singh; Gill, Ritu; Tuteja, Renu; Tuteja, Narendra

2014-01-01

Crop improvement has been a basic and essential chase since organized cultivation of crops began thousands of years ago. Abiotic stresses as a whole are regarded as the crucial factors restricting the plant species to reach their full genetic potential to deliver desired productivity. The changing global climatic conditions are making them worse and pointing toward food insecurity. Agriculture biotechnology or genetic engineering has allowed us to look into and understand the complex nature of abiotic stresses and measures to improve the crop productivity under adverse conditions. Various candidate genes have been identified and transformed in model plants as well as agriculturally important crop plants to develop abiotic stress-tolerant plants for crop improvement. The views presented here are an attempt toward realizing the potential of genetic engineering for improving crops to better tolerate abiotic stresses in the era of climate change, which is now essential for global food security. There is great urgency in speeding up crop improvement programs that can use modern biotechnological tools in addition to current breeding practices for providing enhanced food security.

A Secure-Enhanced Data Aggregation Based on ECC in Wireless Sensor Networks

2014-04-01

Full Text Available Data aggregation is an important technique for reducing the energy consumption of sensor nodes in wireless sensor networks (WSNs. However, compromised aggregators may forge false values as the aggregated results of their child nodes in order to conduct stealthy attacks or steal other nodes’ privacy. This paper proposes a Secure-Enhanced Data Aggregation based on Elliptic Curve Cryptography (SEDA-ECC. The design of SEDA-ECC is based on the principles of privacy homomorphic encryption (PH and divide-and-conquer. An aggregation tree disjoint method is first adopted to divide the tree into three subtrees of similar sizes, and a PH-based aggregation is performed in each subtree to generate an aggregated subtree result. Then the forged result can be identified by the base station (BS by comparing the aggregated count value. Finally, the aggregated result can be calculated by the BS according to the remaining results that have not been forged. Extensive analysis and simulations show that SEDA-ECC can achieve the highest security level on the aggregated result with appropriate energy consumption compared with other asymmetric schemes.

The system of innovative development of the agroindustrial complex in order to ensure the economic security of the region

Full Text Available The basis for innovative development of the agroindustrial complex is the goals, principles and methods that determine the economic security of the region. The category of “economic security”is often identified with the sustainability, competitiveness and risk-free economy of agricultural and processing enterprises. Ensuring the economically safe functioning of all industries and spheres of regional agribusiness is impossible without interconnection with science and education. The most important principles necessary for the formation in the regional and national agribusinesses of a developed economically secure market of scientific, technical and innovative products for agroindustrial purposes are the following: providing the scientific and research sphere of the agro-industrial complex with highly qualified personnel; ensuring real freedom and independence in the activities of research institutions; the formation of a common interdependent economic space and interest; organization of specialized market structures in the field of research and innovation development; development and application within the regional agro-industrial complex of a scientifically grounded economic mechanism for regulating the functioning and stimulating the development of the market for scientific and technical innovation products. Purposeful development of the civilized market of scientific, technical and innovative products of agro-industrial design with its corresponding structures and organizational-economic mechanism is an objective necessity of functioning of economic security of the national economy. The interests of the economic and food security of the region and the state as a whole need to increase the financing of the agricultural sector and the processing industry to a level that will overcome the investment and innovation crisis caused by sanctions. To this end, we believe it is necessary to finance the innovative investment agrarian fund at the

Comprising 65-70% of the world's oil reserves, the Gulf States (Saudi Arabia, Iran, Iraq, Kuwait, UAE and Qatar) are key countries for the solutions to the energy supply matters of the world. Free flow of oil to the world markets from Gulf region is an indispensable part of the major security issues. The Middle East has had mainly security related problems such as Arab-Israeli wars and conflicts, Arab-Iranian war and conflicts, Arab-Arab war and conflicts, US-Gulf wars and conflicts and more recently radicalism and terrorist attacks. Energy supply security requires the enhancement of the peace and cooperation between countries instead of competition. Preventive policy approaches are more suitable to address energy supply matters. Preventive strategy might be possible with the active participation of NATO within the 'out of area' type operations to the Middle East and quite possibly indirectly to the Asia-Pacific regions. Religious and ethnic radicalism and terrorist attacks has also direct effects over oil supply security matters. (Author)

Full Text Available Building on conceptual work on security and cyber security, the paper explores how different approaches to cyber security are constructed. It outlines structural components and presents four common approaches. Each of them suggests a different role for the actors involved and is motivated and justified by different values such as privacy, economic order and national security. When a cyber security policy or initiative is chosen by policymakers, the analysis of the underlying approach enhances our understanding of how this shapes relationships between actors and of the values prioritised, promoted and inscribed into the concerned technologies.

Quantum communication and quantum cryptography are expected to enhance the transmission rate and the security (confidentiality of data transmission), respectively. We study a new scheme which can potentially bridge an intermediate region covered by these two schemes, which is referred to as quantum photonic network. The basic framework is information theoretically secure communications in a free space optical (FSO) wiretap channel, in which an eavesdropper has physically limited access to the main channel between the legitimate sender and receiver. We first review a theoretical framework to quantify the optimal balance of the transmission efficiency and the security level under power constraint and at finite code length. We then present experimental results on channel characterization based on 10 MHz on-off keying transmission in a 7.8 km terrestrial FSO wiretap channel.This article is part of the themed issue 'Quantum technology for the 21st century'. © 2017 The Author(s).

Full Text Available Mobile ad hoc networks (MANETs are wireless networks consisting of number of autonomous mobile devices temporarily interconnected into a network by wireless media. MANETs become one of the most prevalent areas of research in the recent years. Resource limitations, energy efficiency, scalability, and security are the great challenging issues in MANETs. Due to its deployment nature, MANETs are more vulnerable to malicious attack. The secure routing protocols perform very basic security related functions which are not sufficient to protect the network. In this paper, a secure and fair cluster head selection protocol (SFCP is proposed which integrates security factors into the clustering approach for achieving attacker identification and classification. Byzantine agreement based cooperative technique is used for attacker identification and classification to make the network more attack resistant. SFCP used to solve this issue by making the nodes that are totally surrounded by malicious neighbors adjust dynamically their belief and disbelief thresholds. The proposed protocol selects the secure and energy efficient cluster head which acts as a local detector without imposing overhead to the clustering performance. SFCP is simulated in network simulator 2 and compared with two protocols including AODV and CBRP.

Full Text Available The emergence of an “international community” through accumulation of perceived risks that contrasts with those risks (of considerably lower levels of seriousness compared to those perceived constitutes one of the interesting (or intriguing subjects of risks and disaster studies surrounding the 9/11 era. The constructions of “imaginative geographies”, have frequently been biased in the practices that underlie the mapping of the foreign places tend to put-down the affected regions in their “paintings” for the global community. The latter are subsequently “demonized” in their ratings of competence for participating in world trade, tourism, travel, among other social/cultural, and economic and political activities. The objective of this article is to highlight how the exaggeration of risks (contrasted to actually existing/lived risks, practices that are frequently associated with such adverse “imaginative geographies” poses sub-national regional development dilemma in Nigeria’s Niger Delta. We trace the roots of adverse “imaginative geographies” of Nigeria to the Abacha dictatorship (1993-1997. Then we highlight the mixed characteristics of the Niger Delta conditions during the “return of positive image recapture” by Nigeria’s federal government (re-democratisation of the Fourth Republic, 1999-present, re-branding campaigns; as well as adverse conditions present. Most significantly, we show that despite these adversities, a combination of favorable geographical size, differentiation, sub-national regional security programme formulation and management taking aims at diversification have created “large oases” of peace and security in Cross River State, a part of the Niger Delta that has been completely unscathed by insurgencies of the nearby sub-national region and further away national origin.

Full Text Available The study seeks to examine the Food Security Status of Farming Households in the Forest Belt of the Central Region of Ghana. A multistage sampling technique was used to select the respondents that were interviewed. In all 134 farming households were interviewed but 120 were selected for analysis after removing the questionnaires which were not properly administered. The households were selected from eight communities in two districts. Food consumption data of 851 individuals in 120 households were used for the analysis. The study reveals that the majority of the farming households (60% were found to be food insecure. Further, the Binary Logit Model results reveal that an increase in household's income, having access to credit as well as increase in the quantity of own farm production improve the food security status of farming households in the Forest Belt of the Central Region of Ghana. However, holding all other factors constant, increases in non-working member of households worsens the food security status of farming households. Most of the food insecurity coping strategies adopted by household's are not severe and can only be used to avert the impact of food insecurity on a temporal basis. These results have policy implications for Food Security Status of Farming Households in developing countries.

The US Department of Energy (DOE) and the Russian Special Scientific and Production State Enterprise Eleron have teamed to lead a project to enhance the overall security of Russian Ministry of Atomic Energy (MINATOM) transportation of Special Nuclear Material (SNM) shipments. The effort is called the Railcar Transportation Security Project and is part of the overall DOE Material Protection, Control, and Accounting (MPC and A) program addressing the enhancement of nuclear material control, accounting, and physical protection for Russian SNM. The goal of this MPC and A project is to significantly increase the security of Russian MINATOM highly enriched SNM rail shipments. To accomplish this, the MPC and A Railcar Transportation Security program will provide an enhanced, yet cost effective, railcar transportation security system. The system incorporates a balance between the traditional detection, communications, delay, and response security elements to significantly improve the security of MINATOM SNM shipments. The strategy of this program is to use rapid upgrades to implement mature security technologies as quickly as possible. The rapid upgrades emphasize rapidly deployable delay elements, enhanced radio communications, and intrusion detection and surveillance. Upgraded railcars have begun operation during FY98. Subsequent upgrades will build upon the rapid upgrades and eventually be integrated into a final deployed system configuration. This paper provides an overview of the program, with a summary of performance of the deployed railcars

Freshwater Ecosystem Service Flow Model To Evaluate Regional Water Security: A Case Study In Beijing-Tianjin-Hebei Region, China

Science.gov (United States)

Li, D.; Li, S.

2016-12-01

Freshwater service, as the most important support ecosystem service, is essential to human survival and development. Many studies have evidenced the spatial differences in the supply and demand of ecosystem services and raised the concept of ecosystem service flow. However, rather few studies quantitatively characterize the freshwater service flow. This paper aims to quantify the effect of freshwater ecosystem service flow on downstream areas in Beijing-Tianjin-Hebei (BTH) region, China over 2000, 2005 and 2010. We computed the freshwater ecosystem service provision with InVEST model. We calculated freshwater ecosystem service consumption with water quota method. We simulated the freshwater ecosystem service flow using our simplified flow model and assessed the regional water security with the improved freshwater security index. The freshwater provision service mainly depends on climatic factors that cannot be influenced by management, while the freshwater consumption service is constrained by human activities. Furthermore, the decrease of water quota for agricultural, domestic and industrial water counteracts the impact of increasing freshwater demand. The analysis of freshwater ecosystem service flow reveals that the majority area of the BTH (69.2%) is affected by upstream freshwater. If freshwater ecosystem service flow is considered, the water safety areas of the whole BTH account for 66.9%, 66.1%, 71.3%, which increase 6.4%, 6.8% and 5.7% in 2000, 2005 and 2010, respectively. These results highlight the need to understand the teleconnections between distant freshwater ecosystem service provision and local freshwater ecosystem service use. This approach therefore helps managers choose specific management and investment strategies for critical upstream freshwater provisions across different regions.

Brazilian Hybrid Security in South America

Full Text Available Abstract Existing research on security governance in South America functions on dichotomous lines. Analysis of Brazil’s security practices is a case in point. On the one hand, scholars point out the balance of power and hegemonic institutions as the main discourse in the security practices between Brazil and its South American neighbors. On the other hand, some other emphasize the importance of democracy, cooperation on defense and security, and peaceful conflict resolution between states in the region as indicators for the emergence of a security community between Brazil and its neighbors in the South American region. The way in which multiple orders coexist is not given adequate attention in empirical research. This article seeks to overcome this dichotomy. By foregrounding Brazil’s regional security practices, particularly during the Lula and Rousseff administration, I show the hybrid and sometimes ambivalent security governance system in Brazil, where mechanisms of balance of power and security community overlap in important ways.

The Agricultural Model Intercomparison and Improvement Project (AgMIP) has been working since 2010 to construct a protocol-based framework enabling regional assessments (led by regional experts and modelers) that can provide consistent inputs to global economic and integrated assessment models. These global models can then relay important global-level information that drive regional decision-making and outcomes throughout an interconnected agricultural system. AgMIPs community of nearly 800 climate, crop, livestock, economics, and IT experts has improved the state-of-the-art through model intercomparisons, validation exercises, regional integrated assessments, and the launch of AgMIP programs on all six arable continents. AgMIP is now launching Coordinated Global and Regional Assessments (CGRA) of climate change impacts on agriculture and food security to link global and regional crop and economic models using a protocol-based framework. The CGRA protocols are being developed to utilize historical observations, climate projections, and RCPsSSPs from CMIP5 (and potentially CMIP6), and will examine stakeholder-driven agricultural development and adaptation scenarios to provide cutting-edge assessments of climate changes impact on agriculture and food security. These protocols will build on the foundation of established protocols from AgMIPs 30+ activities, and will emphasize the use of multiple models, scenarios, and scales to enable an accurate assessment of related uncertainties. The CGRA is also designed to provide the outputs necessary to feed into integrated assessment models (IAMs), nutrition and food security assessments, nitrogen and carbon cycle models, and additional impact-sector assessments (e.g., water resources, land-use, biomes, urban areas). This presentation will describe the current status of CGRA planning and initial prototype experiments to demonstrate key aspects of the protocols before wider implementation ahead of the IPCC Sixth Assessment

Pastoralists at War: Violence and Security in the Kenya-Sudan-Uganda Border Region

Directory of Open Access Journals (Sweden)

Jonah Leff

2009-12-01

Full Text Available The majority of those living in the border region of Kenya, Sudan, and Uganda are pastoralists, whose livelihoods are dictated by the upkeep and size of their herds. Harsh environmental conditions force pastoralists to migrate in search of water and pasturelands during the dry season. With limited access to water and competing rights to land, intertribal conflict arises when pastoralists from one tribe enter the territory of another. The increased availability of small arms in the region from past wars increasingly makes ordinary clashes fatal. Governments in the region have responded with heavy-handed coercive disarmament operations. These have led to distrust and subsequent violent clashes between communities and security providers. This report reviews the scale, consequences of, and responses to the many pastoral conflicts, utilizing methodological tools such as key informant interviews, retrospective analysis, and a thorough review of available literature.

Information Analysis Methodology for Border Security Deployment Prioritization and Post Deployment Evaluation

International Nuclear Information System (INIS)

Booker, Paul M.; Maple, Scott A.

2010-01-01

Due to international commerce, cross-border conflicts, and corruption, a holistic, information driven, approach to border security is required to best understand how resources should be applied to affect sustainable improvements in border security. The ability to transport goods and people by land, sea, and air across international borders with relative ease for legitimate commercial purposes creates a challenging environment to detect illicit smuggling activities that destabilize national level border security. Smuggling activities operated for profit or smuggling operations driven by cross border conflicts where militant or terrorist organizations facilitate the transport of materials and or extremists to advance a cause add complexity to smuggling interdiction efforts. Border security efforts are further hampered when corruption thwarts interdiction efforts or reduces the effectiveness of technology deployed to enhance border security. These issues necessitate the implementation of a holistic approach to border security that leverages all available data. Large amounts of information found in hundreds of thousands of documents can be compiled to assess national or regional borders to identify variables that influence border security. Location data associated with border topics of interest may be extracted and plotted to better characterize the current border security environment for a given country or region. This baseline assessment enables further analysis, but also documents the initial state of border security that can be used to evaluate progress after border security improvements are made. Then, border security threats are prioritized via a systems analysis approach. Mitigation factors to address risks can be developed and evaluated against inhibiting factor such as corruption. This holistic approach to border security helps address the dynamic smuggling interdiction environment where illicit activities divert to a new location that provides less resistance

Full Text Available The purpose of the study is to substantiate the food security needs in the regions of Ukraine, as well as the definition of tasks in filling the market with own production products. The obtained results will determine the directions of structural changes in agricultural complexes of the regions and the necessary measures by the public regulatory bodies. Methodology. The research is based on a comparison of results of normative and search forecasts. In developing normative forecasts, the projected population and needs in different types of products according to the norms of rational consumption are taken into account. Search forecasts provide for the definition of a future state of satisfaction with the preservation of existing development trends. The gap between the necessary and projected results determines the task of accelerating growth. In terms of national security, food production should be provided with its own raw material base. Therefore, an analysis of the conditions for the development of livestock and crop production is necessary, which enables to substantiate the directions of systemic changes in agricultural complexes of the regions. In order to ensure positive changes in the structure of agricultural production, strengthening the effectiveness of public regulation on the basis of financial and economic leverage is needed. Results. Regions of Ukraine by territory and population exceed certain countries of the European Union. Significant differences in socio-economic conditions of the regions contribute to the growth of tension in society and migration. The events of recent years indicate the possibility of external interference in the functioning of the regions of Ukraine and the danger of the collapse of cooperative ties. Therefore, it is important to ensure the satisfaction of the immediate needs of the population of each region at the expense of its own production. Among the necessities, food occupies a special place. Complete

Multilateral, regional and bilateral energy trade governance

Energy Technology Data Exchange (ETDEWEB)

Leal-Arcas, Rafael; Grasso, Costantino; Rios, Juan Alemany (Queen Mary Univ. of London (United Kingdom))

2014-12-01

The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

Risk-informed, performance-based safety-security interface

Mrowca, B.; Eltawila, F.

2012-01-01

Safety-security interface is a term that is used as part of the commercial nuclear power security framework to promote coordination of the many potentially adverse interactions between plant security and plant safety. Its object is to prevent the compromise of either. It is also used to describe the concept of building security into a plant's design similar to the long standing practices used for safety therefore reducing the complexity of the operational security while maintaining or enhancing overall security. With this in mind, the concept of safety-security interface, when fully implemented, can influence a plant's design, operation and maintenance. It brings the approach use for plant security to one that is similar to that used for safety. Also, as with safety, the application of risk-informed techniques to fully implement and integrate safety and security is important. Just as designers and operators have applied these techniques to enhance and focus safety, these same techniques can be applied to security to not only enhance and focus the security but also to aid in the implementation of effective techniques to address the safety-security interfaces. Implementing this safety-security concept early within the design process can prevent or reduce security vulnerabilities through low cost solutions that often become difficult and expensive to retrofit later in the design and/or post construction period. These security considerations address many of the same issues as safety in ensuring that the response of equipment and plant personnel are adequate. That is, both safety and security are focused on reaching safe shutdown and preventing radiological release. However, the initiation of challenges and the progression of actions in response these challenges and even the definitions of safe shutdown can be considerably different. This paper explores the techniques and limitations that are employed to fully implement a risk-informed, safety-security interface

Full Text Available The authors’ understanding of neuro-programming is the result of the impact on the human brain of information and communication technology (including educational one, through which in the human brain the programs of manifestation in the ontogenesis of internal creative potentials are written. This article summarizes the history of the formation of key neuro-programming technologies of the human brain as well as proves that the changes in the society’s worldview are caused by the possibilities and quality of neuro-programming technologies that society uses. Having influence over worldview stereotypes and behaviour set by the society, neuro-programming technologies essentially ensure the national security of any state and the peaceful coexistence of states in the regions and on the planet as a whole. Using historical and philosophical methods, methods of conceptualization, systematization, modeling, etc., the authors have come to the conclusion that the modern world lies in a confrontation of security strategies, in which neuro-programming technologies play a key role.

Full Text Available Off-site data storage is one of the most widely used strategies in enterprises of all sizes to improve business continuity. In medium-to-large size enterprises, the off-site data storage processes are usually outsourced to specialized providers. However, outsourcing the storage of critical business information assets raises serious security considerations, some of which are usually either disregarded or incorrectly addressed by service providers. This article reviews these security considerations and presents a radio frequency identification (RFID-based, off-site, data storage management system specifically designed to address security issues. The system relies on a set of security mechanisms or controls that are arranged in security layers or tiers to balance security requirements with usability and costs. The system has been successfully implemented, deployed and put into production. In addition, an experimental comparison with classical bar-code-based systems is provided, demonstrating the system’s benefits in terms of efficiency and failure prevention.

Entanglement enhances security in quantum communication

International Nuclear Information System (INIS)

Demkowicz-Dobrzanski, Rafal; Sen, Aditi; Sen, Ujjwal; Lewenstein, Maciej

2009-01-01

Secret sharing is a protocol in which a 'boss' wants to send a classical message secretly to two 'subordinates', such that none of the subordinates is able to know the message alone, while they can find it if they cooperate. Quantum mechanics is known to allow for such a possibility. We analyze tolerable quantum bit error rates in such secret sharing protocols in the physically relevant case when the eavesdropping is local with respect to the two channels of information transfer from the boss to the two subordinates. We find that using entangled encoding states is advantageous to legitimate users of the protocol. We therefore find that entanglement is useful for secure quantum communication. We also find that bound entangled states with positive partial transpose are not useful as a local eavesdropping resource. Moreover, we provide a criterion for security in secret sharing--a parallel of the Csiszar-Koerner criterion in single-receiver classical cryptography.

Results of a project on development of agro-forestry systems for food security in Carrefour region, Republic of Haiti

Directory of Open Access Journals (Sweden)

Furio Massolino

2011-11-01

Full Text Available Haity has a notable problem of food security, 48% of people have not sufficient food availability, food prices has doubled from 1980 and 1990 and further increased 5 times between 1991 and 2000. Water availability and quality is another problems to be added to food insufficiency. Food deficiency is mitigated by natural food resources in rural areas where many different species are cultivated together but it can be extreme in the towns. Agricultural systems are not efficient and, at the same time, enhance soil and genetic erosion. A development project has been implemented to increase food security over the long term in the geographical area of Carrefour rural area, this comprises a research aimed to increase national food production introducing complex agro-forestry systems. The project has investigated problems and solutions, actions have been started to increase food production, including agronomic training of local farmers, organization of small farmers including legal protection on land tenure, introduction of low input modern agroforestry systems that can diversify food production through the year and reduce soil and genetic erosion. After these results, an intervention project has been approved and funded by EU, then delayed due to the recent civil war, finally it is giving positive results now. The same approach used for this project can be spread in the rest of the Republic of Haiti and, hopefully, to other world regions that have similar problems.

Security in the Baltic region as a Projection of Global Confrontation between Russia and the USA

Directory of Open Access Journals (Sweden)

Vadim Volovoj

2017-03-01

Full Text Available This article considers the problem of security in the Baltic region, namely, that of Poland and the Baltics. The authors rely on the works of Karl Deutsch, Emanuel Adler, on Michael Barnett’s theory of security communities and Barry Buzan’s re­gional security complex theory, address Steven Mann’s controlled chaos theory and the concept of Intermarium. Their starting assumption is that the situation in the Baltic depends largely on the politics of external powers — Russia and the United States, — being a projection of their global geopolitical confrontation. The US strategy thus becomes a major part of the equation. The authors believe that since the end of the second Iraq war the American elite has been divided along ideological lines into adherents of the chaos theory and traditionalists thinking in terms of sharing control with the other centres of global power. The US strategy in the Baltic region does not seek an open military conflict with Russia. On the contrary, the US strives to preserve the current level of confrontation between Russia and the EU, convincing the latter of the reality of the Russian threat. Countries that traditionally support confrontation with Russia, Poland and the Bal­tics, serve as a conduit for Washington strategy in Europe and a cordon sanitaire. This function is implemented through the Intermarium project meant to separate Russia from the EU. The four countries are rather active in this area, striving to attain the status of the US principal partners in the region and Europe in general. To retaliate, Moscow does everything within its power to ‘separate’ Brussels from Washington, yet the US influence is still very strong in Europe.

Nuclear security

International Nuclear Information System (INIS)

1991-12-01

This paper reports that despite their crucial importance to national security, safeguards at the Department of Energy's (DOE) weapons facilities may be falling short. DOE security inspections have identified many weaknesses, including poor performance by members of DOE's security force, poor accountability for quantities of nuclear materials, and the inability of personnel to locate documents containing classified information. About 13 percent of the 2,100 identified weakness resulted in DOE inspectors giving out unsatisfactory security ratings; another 38 percent led to marginal ratings. In addition, DOE's centralized safeguards and security information tracking system lacks current data on whether DOE field offices have corrected the identified weaknesses. Without reliable information, DOE has no way of knowing whether timely action was taken to correct problems, nor can it determine whether weaknesses are systematic. DOE has tried to minimize the impact of these security weaknesses at its facilities by establishing multiple layers of protection measures and instituting interim and compensatory measures for identified weaknesses. DOE is planning enhancements to the centralized tracking system that should improve its reliability and increase its effectiveness

Many gaming companies are enhancing the stability and security of their network or gaming systems in order to enhance the gaming user experience. This article has carried out the research of the cyber security issues in online games by introducing the background and some common cyber security threats, and by proposing the latent solution. Finally, it speculates the future research direction of the cyber security issues of online games in the hope of providing feasible solution and useful information for game operators.

Energy Security and Sub-Saharan Africa

Directory of Open Access Journals (Sweden)

Emily Meierding

2013-02-01

Full Text Available Published by Palgrave MacmillanOver the last decade the topic of energy security has reappeared on global policy agendas. Most analyses of international energy geopolitics examine the interests and behaviour of powerful energy-importing countries like the US and China. This chapter begins by examining foreign powers’ expanded exploitation of oil and uranium resources in Sub-Saharan Africa. It goes on to examine how energy importers’ efforts to enhance their energy security through Africa are impacting energy security within Africa. It assesses Sub-Saharan states’ attempts to increase consumption of local oil and uranium reserves. Observing the constraints on these efforts, it then outlines some alternative strategies that have been employed to enhance African energy security. It concludes that, while local community-based development projects have improved the well-being of many households, they are not a sufficient guarantor of energy security. Inadequate petroleum access, in particular, remains a development challenge. Foreign powers’ efforts to increase their oil security are undermining the energy security of Sub-Saharan African citizens.

Household food security and adequacy of child diet in the food insecure region north in Ghana.

Full Text Available Adequate diet is of crucial importance for healthy child development. In food insecure areas of the world, the provision of adequate child diet is threatened in the many households that sometimes experience having no food at all to eat (household food insecurity. In the context of food insecure northern Ghana, this study investigated the relationship between level of household food security and achievement of recommended child diet as measured by WHO Infant and Young Child Feeding Indicators.Using data from households and 6-23 month old children in the 2012 Feed the Future baseline survey (n = 871, descriptive analyses assessed the prevalence of minimum meal frequency; minimum dietary diversity, and minimum acceptable diet. Logistic regression analysis was used to examine the association of minimum acceptable diet with household food security, while accounting for the effects of child sex and age, maternal -age, -dietary diversity, -literacy and -education, household size, region, and urban-rural setting. Household food security was assessed with the Household Hunger Scale developed by USAID's Food and Nutrition Technical Assistance Project.Forty-nine percent of children received minimum recommended meal frequency, 31% received minimum dietary diversity, and 17% of the children received minimum acceptable diet. Sixty-four percent of the children lived in food secure households, and they were significantly more likely than children in food insecure households to receive recommended minimum acceptable diet [O.R = 0.53; 95% CI: 0.35, 0.82]. However, in 80% of food secure households, children did not receive a minimal acceptable diet by WHO standards.Children living in food secure households were more likely than others to receive a minimum acceptable diet. Yet living in a food secure household was no guarantee of child dietary adequacy, since eight of 10 children in food secure households received less than a minimum acceptable diet. The results

Enhancing MISP with Fast Mobile IPv6 Security

Directory of Open Access Journals (Sweden)

Ilsun You

2011-01-01

Full Text Available The Mobile Broadband Association has developed the MIS and MISAUTH protocols as link-layer fast authentication protocols. A combination of MIS and MISAUTH protocols, called as MISP, provides secure and fast connection for a wireless access network, but it has been reported that MISP creates a weak session key and suffers from a denial-of-service attack. In addition, a transaction with an authentication server that is required for every authentication is considered as a delay factor during handovers. In this paper, we present an improvement of MISP that utilizes the fast handover approach of Fast Mobile IPv6 and minimizes an involvement of the authentication server while eliminating identified security drawbacks of MISP. The formal security analysis is performed to verify the correctness of the proposed scheme. Moreover, the handover performance of the proposed scheme is compared with an existing scheme.

Enhanced Secure Trusted AODV (ESTA Protocol to Mitigate Blackhole Attack in Mobile Ad Hoc Networks

2015-09-01

Full Text Available The self-organizing nature of the Mobile Ad hoc Networks (MANETs provide a communication channel anywhere, anytime without any pre-existing network infrastructure. However, it is exposed to various vulnerabilities that may be exploited by the malicious nodes. One such malicious behavior is introduced by blackhole nodes, which can be easily introduced in the network and, in turn, such nodes try to crumble the working of the network by dropping the maximum data under transmission. In this paper, a new protocol is proposed which is based on the widely used Ad hoc On-Demand Distance Vector (AODV protocol, Enhanced Secure Trusted AODV (ESTA, which makes use of multiple paths along with use of trust and asymmetric cryptography to ensure data security. The results, based on NS-3 simulation, reveal that the proposed protocol is effectively able to counter the blackhole nodes in three different scenarios.

Collaborative eHealth Meets Security: Privacy-Enhancing Patient Profile Management.

Sanchez-Guerrero, Rosa; Mendoza, Florina Almenarez; Diaz-Sanchez, Daniel; Cabarcos, Patricia Arias; Lopez, Andres Marin

2017-11-01

Collaborative healthcare environments offer potential benefits, including enhancing the healthcare quality delivered to patients and reducing costs. As a direct consequence, sharing of electronic health records (EHRs) among healthcare providers has experienced a noteworthy growth in the last years, since it enables physicians to remotely monitor patients' health and enables individuals to manage their own health data more easily. However, these scenarios face significant challenges regarding security and privacy of the extremely sensitive information contained in EHRs. Thus, a flexible, efficient, and standards-based solution is indispensable to guarantee selective identity information disclosure and preserve patient's privacy. We propose a privacy-aware profile management approach that empowers the patient role, enabling him to bring together various healthcare providers as well as user-generated claims into an unique credential. User profiles are represented through an adaptive Merkle Tree, for which we formalize the underlying mathematical model. Furthermore, performance of the proposed solution is empirically validated through simulation experiments.

Transparency and nonproliferation in the Asia-Pacific region. Enhancing transparency, strengthening the nonproliferation regime

International Nuclear Information System (INIS)

Hamada, Kazuko

2008-01-01

Driven by the prospect of rapid economic growth and the perceived need for energy security, the Asia-Pacific region is destined to increase its nuclear energy use in the coming decades. This projected increase, however, will bring with it nuclear proliferation concerns, fueling fears about the security of nuclear material and creating suspicions about its use. The increasing use of nuclear energy inevitably necessitates supplementary efforts, designed to ensure nuclear security and a legitimate use of nuclear energy, other than the obligation to the Treaty on the Nonproliferation of Nuclear Weapons (NPT). Nuclear transparency measures could be useful tools for building confidence that the increasing nuclear energy use does not contribute to nuclear proliferation. These measures could also foster a cooperative tradition that can address rising concerns over nuclear trafficking and terrorism, which require regional coordination to combat. However, moderate progress in implementing transparency measures suggests a lack of political appreciation of this concept. Thus, this paper describes various forms of potential transparency measures to expand the possibilities of the transparency concept and explore areas in which this concept might be applicable. This paper also clarifies some challenges involving transparency projects, and suggests possible ways to address these challenges. (author)

Seed security is of prime importance for agriculture. To protect true seeds from being faked, more secure dual anti-counterfeiting technologies for tobacco (Nicotiana tabacum L.) pelleted seed were developed in this paper. Fluorescein (FR), rhodamine B (RB), and magnetic powder (MP) were used as anti-counterfeiting labels. According to their different properties and the special seed pelleting process, four dual-labeling treatments were conducted for two tobacco varieties, MS Yunyan85 (MSYY85) and Honghua Dajinyuan (HHDJY). Then the seed germination and seedling growth status were investigated, and the fluorescence in cracked pellets and developing seedlings was observed under different excitation lights. The results showed that FR, RB, and MP had no negative effects on the germination, seedling growth, and MDA content of the pelleted seeds, and even some treatments significantly enhanced seedling dry weight, vigor index, and shoot height in MS YY85, and increased SOD activity and chlorophyll content in HHDJY as compared to the control. In addition, the cotyledon tip of seedlings treated with FR and MP together represented bright green fluorescence under illumination of blue light (478 nm). And the seedling cotyledon vein treated with RB and MP together showed red fluorescence under green light (546 nm). All seeds pelleted with magnetic powder of proper concentration could be attracted by a magnet. Thus, it indicated that those new dual-labeling methods that fluorescent compound and magnetic powder simultaneously applied in the same seed pellets definitely improved anti-counterfeiting technology and enhanced the seed security. This technology will ensure that high quality seed will be used in the crop production.

Full Text Available The images are very largely used in our daily life; the security of their transfer became necessary. In this work a novel image encryption scheme using stream cipher algorithm based on nonlinear combination generator is developed. The main contribution of this work is to enhance the security of encrypted image. The proposed scheme is based on the use the several linear feedback shifts registers whose feedback polynomials are primitive and of degrees are all pairwise coprimes combined by resilient function whose resiliency order, algebraic degree and nonlinearity attain Siegenthaler’s and Sarkar, al.’s bounds. This proposed scheme is simple and highly efficient. In order to evaluate performance, the proposed algorithm was measured through a series of tests. These tests included visual test and histogram analysis, key space analysis, correlation coefficient analysis, image entropy, key sensitivity analysis, noise analysis, Berlekamp-Massey attack, correlation attack and algebraic attack. Experimental results demonstrate the proposed system is highly key sensitive, highly resistance to the noises and shows a good resistance against brute-force, statistical attacks, Berlekamp-Massey attack, correlation attack, algebraic attack and a robust system which makes it a potential candidate for encryption of image.

Full Text Available Modern technology enhancements have been used worldwide to fulfill the requirements of the industrial sector, especially in supervisory control and data acquisition (SCADA systems as a part of industrial control systems (ICS. SCADA systems have gained popularity in industrial automations due to technology enhancements and connectivity with modern computer networks and/or protocols. The procurement of new technologies has made SCADA systems important and helpful to processing in oil lines, water treatment plants, and electricity generation and control stations. On the other hand, these systems have vulnerabilities like other traditional computer networks (or systems, especially when interconnected with open platforms. Many international organizations and researchers have proposed and deployed solutions for SCADA security enhancement, but most of these have been based on node-to-node security, without emphasizing critical sessions that are linked directly with industrial processing and automation. This study concerns SCADA security measures related to critical processing with specified sessions of automated polling, analyzing cryptography mechanisms and deploying the appropriate explicit inclusive security solution in a distributed network protocol version 3 (DNP3 stack, as part of a SCADA system. The bytes flow through the DNP3 stack with security computational bytes within specified critical intervals defined for polling. We took critical processing knowledge into account when designing a SCADA/DNP3 testbed and deploying a cryptography solution that did not affect communications.

Traditional notions of security are premised on the primacy of state security. In relation to energy security, traditional policy thinking has focused on ensuring supply without much emphasis on socioeconomic and environmental impacts. Non-traditional security (NTS) scholars argue that threats to human security have become increasingly prominent since the end of the Cold War, and that it is thus critical to adopt a holistic and multidisciplinary approach in addressing rising energy needs. This volume represents the perspectives of scholars from across Asia, looking at diverse aspects of energy security through a non-traditional security lens. The issues covered include environmental and socioeconomic impacts, the role of the market, the role of civil society, energy sustainability and policy trends in the ASEAN region.

In the past many DOE and DoD facilities involved in handling nuclear material realized a need to enhance the safely and security for movement of sensitive materials within their facility, or ''intra-site''. There have been prior efforts to improve on-site transportation; however, there remains a requirement for enhanced on-site transportation at a number of facilities. The requirements for on-site transportation are driven by security, safety, and operational concerns. The Intra-site Secure Transport Vehicle (ISTV) was designed to address these concerns specifically for DOE site applications with a standardized vehicle design. This paper briefly reviews the ISTV design features providing significant enhancement of onsite transportation safety and security, and also describes the test and evaluation activities either complete of underway to validate the vehicle design and operation

The growth of image processing in embedded system has provided the boon of enhancing the security in various sectors. This lead to the developing of various protective strategies, which will be needed by private or public sectors for cyber security purposes. So, we have developed a method which uses digital water marking and locking mechanism for the protection of any closed premises. This paper describes a contemporary system based on user name, user id, password and encryption technique which can be placed in banks, protected offices to beef the security up. The burglary can be abated substantially by using a proactive safety structure. In this proposed framework, we are using water-marking in spatial domain to encode and decode the image and PIR(Passive Infrared Sensor) sensor to detect the existence of person in any close area.

Full Text Available This paper presents tunneling field-effect transistor (TFET with dual source regions. It explores the physics of drive current enhancement. The novel approach of dual source provides an effective technique for enhancing the drive current. It is found that this structure can offer four tunneling junctions by increasing a source region. Meanwhile, the dual source structure does not influence the excellent features of threshold slope (SS of TFET. The number of the electrons and holes would be doubled by going through the tunneling junctions on the original basis. The overlap length of gate-source is also studied. The dependence of gate-drain capacitance Cgd and gate-source capacitance Cgs on gate-to-source voltage Vgs and drain-to-source voltage Vds was further investigated. There are simulation setups and methodology used for the dual source TFET (DS-TFET assessment, including delay time, total energy per operation, and energy-delay product. It is confirmed that the proposed TFET has strong potentials for VLSI.

SHOX alterations have been reported in 67% of patients affected by Léri-Weill dyschondrosteosis (LWD), with a larger prevalence of gene deletions than point mutations. It has been recently demonstrated that these deletions can involve the SHOX enhancer region, rather that the coding region, with variable phenotype of the affected patients.Here, we report a SHOX gene analysis carried out by MLPA in 14 LWD patients from 4 families with variable phenotype. All patients presented a SHOX enhancer deletion. In particular, a patient with a severe bilateral Madelung deformity without short stature showed a homozygous alteration identical to the recently described 47.5 kb PAR1 deletion. Moreover, we identified, for the first time, in three related patients with a severe bilateral Madelung deformity, a smaller deletion than the 47.5 kb PAR1 deletion encompassing the same enhancer region (ECR1/CNE7). Data reported in this study provide new information about the spectrum of phenotypic alterations showed by LWD patients with different deletions of the SHOX enhancer region.

Power allocation and cooperative jamming for enhancing physical layer security in opportunistic relay networks in the presence of interference

2017-01-01

In this paper, the impact of cochannel interference on the secrecy performance of dual-hop decode-and-forward relaying is investigated. In particular, the outage and intercept probabilities are obtained for the opportunistic relay selection (ORS) model in the presence of nonidentical interfering signals under a single/multiple passive eavesdropper(s) attack. Moreover, the proposed work enhances physical layer security performance of ORS model using cooperative jamming (CJ) techniques. Therefore, new closed-form expressions are derived for the intercept and outage probabilities of the CJ-ORS model in the presence of interference over Rayleigh fading channels. Moreover, the analyses are generalized to the case of multiple eavesdroppers where closed-form expressions are derived for the intercept probability. To reveal more insights on the proposed work secrecy performance, asymptotic closed-form expressions for the intercept and outage probabilities are obtained. Using these asymptotic expressions, a power allocation optimization problem is formulated and solved for enhancing the system security. The derived analytical formulas herein are supported by numerical and simulation results to clarify the main contributions of the paper. The results show that, although the cochannel interference increases the system outage probability, it might improve the system secrecy performance. Moreover, the proposed CJ-ORS model is shown to enhance the system secrecy performance compared to ORS model.

Complex systems are comprised of technical, social, political and environmental factors as well as the programmatic factors of cost, schedule and risk. Testing these systems for enhanced security requires expert knowledge in many different fields. It is important to test these systems to ensure effectiveness, but testing is limited to due cost, schedule, safety, feasibility and a myriad of other reasons. Without an effective decision framework for Test and Evaluation (T&E) planning that can take into consideration technical as well as programmatic factors and leverage expert knowledge, security in complex systems may not be assessed effectively. Therefore, this paper covers the identification of the current T&E planning problem and an approach to include the full variety of factors and leverage expert knowledge in T&E planning through the use of Bayesian Networks (BN).

The Internet of Things (IoT) utilizes algorithms to facilitate intelligent applications across cities in the form of smart-urban projects. As the majority of devices in IoT are battery operated, their applications should be facilitated with a low-power communication setup. Such facility is possible through the Low-Power Wide-Area Network (LPWAN), but at a constrained bit rate. For long-range communication over LPWAN, several approaches and protocols are adopted. One such protocol is the Long-Range Wide Area Network (LoRaWAN), which is a media access layer protocol for long-range communication between the devices and the application servers via LPWAN gateways. However, LoRaWAN comes with fewer security features as a much-secured protocol consumes more battery because of the exorbitant computational overheads. The standard protocol fails to support end-to-end security and perfect forward secrecy while being vulnerable to the replay attack that makes LoRaWAN limited in supporting applications where security (especially end-to-end security) is important. Motivated by this, an enhanced LoRaWAN security protocol is proposed, which not only provides the basic functions of connectivity between the application server and the end device, but additionally averts these listed security issues. The proposed protocol is developed with two options, the Default Option (DO) and the Security-Enhanced Option (SEO). The protocol is validated through Burrows⁻Abadi⁻Needham (BAN) logic and the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. The proposed protocol is also analyzed for overheads through system-based and low-power device-based evaluations. Further, a case study on a smart factory-enabled parking system is considered for its practical application. The results, in terms of network latency with reliability fitting and signaling overheads, show paramount improvements and better performance for the proposed protocol compared with the two

Today, security is a prominent issue when any type of communication is being undertaken. Like traditional networks, supervisory control and data acquisition (SCADA) systems suffer from a number of vulnerabilities. Numerous end-to-end security mechanisms have been proposed for the resolution of SCADA-system security issues, but due to insecure real-time protocol use and the reliance upon open protocols during Internet-based communication, these SCADA systems can still be compromised by security challenges. This study reviews the security challenges and issues that are commonly raised during SCADA/protocol transmissions and proposes a secure distributed-network protocol version 3 (DNP3) design, and the implementation of the security solution using a cryptography mechanism. Due to the insecurities found within SCADA protocols, the new development consists of a DNP3 protocol that has been designed as a part of the SCADA system, and the cryptographically derived security is deployed within the application layer as a part of the DNP3 stack.

Current social and environmental changes in the Arctic challenge the health and well-being of its residents. Developing evidence-informed adaptive measures in response to these changes is a priority for communities, governments and researchers. To develop strategic planning to promote food security and food safety in the Inuvialuit Settlement Region (ISR), Northwest Territories (NWT), Canada. A qualitative study using group discussions during a workshop. A regional workshop gathered Inuit organizations and community representatives, university-based researchers from the Inuit Health Survey (IHS) and NWT governmental organizations. Discussions were structured around the findings from the IHS. For each key area, programs and activities were identified and prioritized by group discussion and voting. The working group developed a vision for future research and intervention, which is to empower communities to promote health, well-being and environmental sustainability in the ISR. The group elaborated missions for the region that address the following issues: (a) capacity building within communities; (b) promotion of the use of traditional foods to address food security; (c) research to better understand the linkages between diseases and contaminants in traditional foods, market foods and lifestyle choices; (d) and promotion of affordable housing. Five programs to address each key area were developed as follows: harvest support and traditional food sharing; education and promotion; governance and policy; research; and housing. Concrete activities were identified to guide future research and intervention projects. The results of the planning workshop provide a blueprint for future research and intervention projects.

Security enhanced BioEncoding for protecting iris codes

Ouda, Osama; Tsumura, Norimichi; Nakaguchi, Toshiya

2011-06-01

Improving the security of biometric template protection techniques is a key prerequisite for the widespread deployment of biometric technologies. BioEncoding is a recently proposed template protection scheme, based on the concept of cancelable biometrics, for protecting biometric templates represented as binary strings such as iris codes. The main advantage of BioEncoding over other template protection schemes is that it does not require user-specific keys and/or tokens during verification. Besides, it satisfies all the requirements of the cancelable biometrics construct without deteriorating the matching accuracy. However, although it has been shown that BioEncoding is secure enough against simple brute-force search attacks, the security of BioEncoded templates against more smart attacks, such as record multiplicity attacks, has not been sufficiently investigated. In this paper, a rigorous security analysis of BioEncoding is presented. Firstly, resistance of BioEncoded templates against brute-force attacks is revisited thoroughly. Secondly, we show that although the cancelable transformation employed in BioEncoding might be non-invertible for a single protected template, the original iris code could be inverted by correlating several templates used in different applications but created from the same iris. Accordingly, we propose an important modification to the BioEncoding transformation process in order to hinder attackers from exploiting this type of attacks. The effectiveness of adopting the suggested modification is validated and its impact on the matching accuracy is investigated empirically using CASIA-IrisV3-Interval dataset. Experimental results confirm the efficacy of the proposed approach and show that it preserves the matching accuracy of the unprotected iris recognition system.

Objective: To explore the clinical value of duralphase enhanced electronic beam computed tomography (EBCT) scans in resectability evaluation of lung cancer located in hilar region. Methods: Dual phase enhanced EBCT scans were available for 40 cases that were initially diagnosed as 'carcinoma of lung' in hilar region. The relations between masses and trachea, bronchi, hilar and mediastinal great vessels were analyzed and compared with operation. Results: 38 cases in our series confirmed by operation and pathological examination were divided two groups: respectable (28 cases) and non-resectable (10 cases) groups. 25 cases in the former group were consistent with operation, accounting for 89.3%, and 8 cases, in the latter group, accounting for 80%. The sensitivity, specificity and accuracy of dural-phase enhanced EBCT scan evaluating the relations between masses and hilar and mediastinal structure were as follows: 92.6%, 72.7% and 86.8%. Conclusion: Dural-phase enhanced EBCT scans can provide precise and feasible pre-operative evaluation of lung cancer in hilar region. (authors)

Christopher A Pepping

Full Text Available Recent research suggests that attachment and mindfulness are related, though the nature of this association is unclear. Here we present two studies examining whether there is a causal relationship between state attachment and state mindfulness. Study 1 investigated the effects of experimentally increasing state mindfulness on state attachment security. State mindfulness was successfully enhanced, but this led to no change in state attachment security. Study 2 investigated the effects of experimentally enhancing state attachment security on state mindfulness. State attachment security was successfully enhanced, but this did not lead to any change in state mindfulness. These findings suggest that there is not a direct, immediate causal relationship between state attachment and state mindfulness as a result of brief experimental manipulations. Future research should examine these associations in longer term interventions.

In light of recent attacks, and resulting embassy closures, Yemen is a rising priority in the Western-led War on Terror. However, this has resulted in a side-lining of other security threats in Yemen, which may cause serious challenges to the authority of the Yemeni Government. In reality, the role of AQAP has been heavily manipulated throughout Yemen’s contemporary history: this was most evident during the 2011 Arab Spring, when both sides in the conflict claimed that Al Qaeda operatives were working with members of the other. Two years later, the true nature of the AQAP threat in Yemen is rarely questioned by external observers, yet remains largely shrouded in mystery. There is a need for more critical approaches to the AQAP challenges, which take the broader context of Yemeni security into account.

To explore how determinants of food security affect children in regional and remote Western Australia (WA), across food availability, access and utilisation dimensions. The Determinants of Food Security framework guided the thematic analysis (using NVivo 10) of semi-structured interviews with 20 key informants. Food availability factors included availability, price, promotion, quality, location of outlets and variety. Food access factors included social support, financial resources, transport to food outlets, distance to food outlets and mobility. Food utilisation factors included nutrition knowledge and skills, children's food preferences, storage facilities, preparation and cooking facilities and time to purchase food. Key food availability recommendations include increasing local food supply options. Food access recommendations include ensuring equitable formal social support and empowering informal support options. Food utilisation recommendations include prioritising food literacy programs focusing on quick, healthy food preparation and budgeting skills. Implications for public health: Policymakers should invest in local food supply options, equitable social support services and experiential food literacy programs. Practitioners should focus child/parent programs on improving attitude, knowledge and skills. © 2017 Public Health Association of Australia.

Full-text: The need for human resource development programmes in nuclear security was underlined at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors Meetings. Successive IAEA Nuclear Security Plans, the most recent of which was agreed by the Board of Governors in September 2009, give high priority to assisting States in establishing educational programmes in nuclear security in order to ensure the sustainability of nuclear security improvements. The current Nuclear Security Plan 1 covering 2010-2013 emphasizes on the importance of considering existing capacities at international, regional and national levels while designing nuclear security academic programmes. In the course of implementing the Plan, the IAEA developed a guide entitled Educational Programme in Nuclear Security (IAEA Nuclear Security Series No. 12) that consists of a model of a MAster of Science (M.Sc.) and a Certificate Programme in Nuclear Security. This guide was aims at assisting universities or other educational institutes to developed academic programmes in nuclear security. Independently, some universities already offered academic programmes covering some areas of nuclear security, while other universities have asked the IAEA to support the implementation of these programmes. In order to better address current and future request for assistance in this area, the IAEA establish a collaboration network-International Nuclear Security Education Network (INSEN), among universities who are providing nuclear security education or who are interested in starting an academic programme/ course(s) in nuclear security. Universiti Kebangsaan Malaysia (UKM) is a first local university became a member of INSEN since the beginning of the establishment. (author)

You're never quite finished with nuclear security. ''Even the most advanced security system for radioactive or nuclear material needs to be continuously updated to ensure that it remains effective,'' says Arvydas Stadalnikas, an IAEA Senior Nuclear Security Officer. ''Security can always be improved. Even if you think you have the best system for today, it may require enhancements because of the changing environment,'' he said. To help States with this daunting task, the IAEA offers support through its International Physical Protection Advisory Service (IPPAS) which includes in-depth analysis of the physical protection and nuclear security followed by expert advice. The IAEA has carried out 58 missions to 37 countries since the IPPAS programme was launched in 1996, helping States translate international conventions, codes and guidance on nuclear security into practice. Although each mission focuses on improving the security in a specific country, ''the programme has benefits that reach far beyond the recipient State's national borders,'' Stadalnikas noted. ''Each IPPAS mission helps improve global nuclear security because enhanced security in one country means that you improve globally. Deficiencies in one country could open the way for malicious acts, which can have worldwide effects,'' he said

2003-01-01

The demise of the Soviet Union and its subsequent break-up into 15 independent states gave rise to totally new political and strategic circumstances, which also extended into Central Eurasia and the Caspian Region. The eight newly independent states of this region have become one of the most important geopolitical areas in the post-Cold War era, due to a combination of its geographical position and significant oil and gas reserves. The region's resources are vital for advanced industrialised countries and figure prominently in Western geostrategic and economic interests in the twenty-first century. Intense competition, as well as co-operation, among various state and non-state actors for the control of these resources is emerging, also known as the New Great Game. The main actors involved in Central Eurasia and the Caspian region are identified as follows: inner circle actors (Russia, Iran, and Turkey), outer circle actors (China, India, Pakistan, and Afghanistan), external actors (the United States, the European Union and its particular member states), and non-state actors (ethno-religious groups, Transnational Corporations, crime groups, etc.). The author analyses the New Great Game by using a neo-geopolitical perspective. An important element towards control of the region's energy resources is the construction of transport routes. The question of where to construct pipelines engenders considerable conflicts between the interested players that could create obstacles to building the most economically viable and secure pipelines. Transportation of energy resources to the global market is also subject to conflicts between different forces within the Central Eurasian region, including ethno-religious conflicts. Problems such as lack of infrastructure and technology, and finding a solution for the Caspian legal regime dispute could pose further obstacles to prospective pipeline construction.

Full Text Available We chose this theme to highlight the need for continuous and sustained human society to secure energy resources needed to survive, needs reflected in an increasingly in recent years in the strategies adopted at both states, as at the level of international organizations. Achieving security and stability in the wider Black Sea area has been among the priorities of each country's interests in this region. In this context, state and non-state actors were being called to come up with new solutions to achieve those interests. Certainly not in all cases the negotiations were completed or not yet found a generally accepted formula for others to apply, but most of them show off their values. The main environmental threats to security environment in the Black Sea region are represented by ethnic conflicts and territorial secessionism. A significant contribution to the security environment of the Black Sea region has the phenomenon of globalization, which in this region is manifested by a steady increase in traffic and volume of shipping passage of communication, which largely affects the security in the region. Globalization and the need for energy resources in the Black Sea was an important area not only as energy transport route, but as a potential supplier of material energy (oil and natural gas. Black Sea Basin can be stabilized and secured only by the will and input from all States and interested international organizations in pragmatic and effective institutional frameworks, meant to promote and protect the common interests of countries decided to participate in actions aimed at ensuring a stable environment security.

Security, insecurity and health.

Coupland, Robin

2007-03-01

An examination of the nexus of security, insecurity and health shows that security is a prerequisite for health. The many and varied ways that armed violence--including threats of armed violence--can affect people's health can be documented by formal studies; however, valuable data also exist in other reports, such as media reports. The health community needs to recognize that people's insecurity is a massive global health issue. The foreign policies of donor governments should incorporate recognition that documentation, analysis and publication of data describing the impact of insecurity on people's health can lead to the creation of policies to enhance people's security.

Tang, Wan; Chen, Min; Ni, Jin; Yang, Ximin

2011-01-01

The traditional Radio Frequency Identification (RFID) system, in which the information maintained in tags is passive and static, has no intelligent decision-making ability to suit application and environment dynamics. The Second-Generation RFID (2G-RFID) system, referred as 2G-RFID-sys, is an evolution of the traditional RFID system to ensure better quality of service in future networks. Due to the openness of the active mobile codes in the 2G-RFID system, the realization of conveying intelligence brings a critical issue: how can we make sure the backend system will interpret and execute mobile codes in the right way without misuse so as to avoid malicious attacks? To address this issue, this paper expands the concept of Role-Based Access Control (RBAC) by introducing context-aware computing, and then designs a secure middleware for backend systems, named Two-Level Security Enhancement Mechanism or 2L-SEM, in order to ensure the usability and validity of the mobile code through contextual authentication and role analysis. According to the given contextual restrictions, 2L-SEM can filtrate the illegal and invalid mobile codes contained in tags. Finally, a reference architecture and its typical application are given to illustrate the implementation of 2L-SEM in a 2G-RFID system, along with the simulation results to evaluate how the proposed mechanism can guarantee secure execution of mobile codes for the system.

The US ballistic missile defence policy in the Baltic and Nordic regions

Directory of Open Access Journals (Sweden)

Konyshev Valery

2016-03-01

Full Text Available This article examines the implications of the deployment of the US ballistic missile defense (BMD system in the Baltic and Nordic regions. These implications are to be considered to ensure Russia’s military security. Using the structural-functional method, the authors analyse the internal structure of the US BMD in Europe, stages of its implementation, and its influence on the military equilibrium in the region. Being similar to other regional missile defence systems of the Pentagon, BMD in Europe increases the offensive capabilities of the US armed forces and its allies and in doing so, it stops performing a purely defensive mission declared by Washington. It is stressed that the deployment of mobile sea- and land-based BMD elements in the Baltic Sea region and Nordic countries will inevitably destabilize the strategic situation and may lead to a new round of arms race in the region. The efficacy of BMD in Europe is evaluated from the perspective of military technology. The system’s potential threats to Russia’s military security and its armed forces are assessed. The article considers measures to enhance national security that could be taken by Russia provided the US plans to deploy BMD in Europe are fully implemented.

2012-09-01

Full Text Available Designing secure and robust grouping-proof protocols based on RFID characteristics becomes a hotspot in the research of security in Internet of Things (IOT. The proposed grouping-proof protocols recently have security and/or privacy omission and these schemes afford order-dependence by relaying message among tags through an RFID reader. In consequence, aiming at enhancing the robustness, improving scalability, reducing the computation costs on resource-constrained devices, and meanwhile combing Computational Intelligence (CI with Secure Multi-party Communication (SMC, a Forward-Secure Grouping-Proof Protocol (FSGP for multiple RFID tags based on Shamir's (, secret sharing is proposed. In comparison with the previous grouping-proof protocols, FSGP has the characteristics of forward-security and order-independence addressing the scalability issue by avoiding relaying message. Our protocol provides security enhancement, performance improvement, and meanwhile controls the computation cost, which equilibrates both security and low cost requirements for RFID tags.

Multitask Learning-Based Security Event Forecast Methods for Wireless Sensor Networks

Directory of Open Access Journals (Sweden)

Hui He

2016-01-01

Full Text Available Wireless sensor networks have strong dynamics and uncertainty, including network topological changes, node disappearance or addition, and facing various threats. First, to strengthen the detection adaptability of wireless sensor networks to various security attacks, a region similarity multitask-based security event forecast method for wireless sensor networks is proposed. This method performs topology partitioning on a large-scale sensor network and calculates the similarity degree among regional subnetworks. The trend of unknown network security events can be predicted through multitask learning of the occurrence and transmission characteristics of known network security events. Second, in case of lacking regional data, the quantitative trend of unknown regional network security events can be calculated. This study introduces a sensor network security event forecast method named Prediction Network Security Incomplete Unmarked Data (PNSIUD method to forecast missing attack data in the target region according to the known partial data in similar regions. Experimental results indicate that for an unknown security event forecast the forecast accuracy and effects of the similarity forecast algorithm are better than those of single-task learning method. At the same time, the forecast accuracy of the PNSIUD method is better than that of the traditional support vector machine method.

Partial Fingerprint Image Enhancement using Region Division Technique and Morphological Transform

International Nuclear Information System (INIS)

Ahmad, A.; Arshad, I.; Raja, G.

2015-01-01

Fingerprints are the most renowned biometric trait for identification and verification. The quality of fingerprint image plays a vital role in feature extraction and matching. Existing algorithms work well for good quality fingerprint images and fail for partial fingerprint images as they are obtained from excessively dry fingers or affected by disease resulting in broken ridges. We propose an algorithm to enhance partial fingerprint images using morphological operatins with region division technique. The proposed method divides low quality image into six regions from top to bottom. Morphological operations choose an appropriate Structuring Element (SE) that joins broken ridges and thus enhance the image for further processing. The proposed method uses SE line with suitable angle theta and radius r in each region based on the orientation of the ridges. The algorithm is applied to 14 low quality fingerprint images from FVC-2002 database. Experimental results show that percentage accuracy has been improved using the proposed algorithm. The manual markup has been reduced and accuracy of 76.16% with Equal Error Rate (EER) of 3.16% is achieved. (author)

Enhancement of bone shadow region using local phase-based ultrasound transmission maps.

Science.gov (United States)

Hacihaliloglu, Ilker

2017-06-01

Ultrasound is increasingly being employed in different orthopedic procedures as an imaging modality for real-time guidance. Nevertheless, low signal-to-noise-ratio and different imaging artifacts continue to hamper the success of ultrasound-based procedures. Bone shadow region is an important feature indicating the presence of bone/tissue interface in the acquired ultrasound data. Enhancement and automatic detection of this region could improve the sensitivity of ultrasound for imaging bone and result in improved guidance for various orthopedic procedures. In this work, a method is introduced for the enhancement of bone shadow regions from B-mode ultrasound data. The method is based on the combination of three different image phase features: local phase tensor, local weighted mean phase angle, and local phase energy. The combined local phase image features are used as an input to an [Formula: see text] norm-based contextual regularization method which emphasizes uncertainty in the shadow regions. The enhanced bone shadow images are automatically segmented and compared against expert segmentation. Qualitative and quantitative validation was performed on 100 in vivo US scans obtained from five subjects by scanning femur and vertebrae bones. Validation against expert segmentation achieved a mean dice similarity coefficient of 0.88. The encouraging results obtained in this initial study suggest that the proposed method is promising enough for further evaluation. The calculated bone shadow maps could be incorporated into different ultrasound bone segmentation and registration approaches as an additional feature.

A Secure ECC-based RFID Mutual Authentication Protocol to Enhance Patient Medication Safety.

Science.gov (United States)

Jin, Chunhua; Xu, Chunxiang; Zhang, Xiaojun; Li, Fagen

2016-01-01

Patient medication safety is an important issue in patient medication systems. In order to prevent medication errors, integrating Radio Frequency Identification (RFID) technology into automated patient medication systems is required in hospitals. Based on RFID technology, such systems can provide medical evidence for patients' prescriptions and medicine doses, etc. Due to the mutual authentication between the medication server and the tag, RFID authentication scheme is the best choice for automated patient medication systems. In this paper, we present a RFID mutual authentication scheme based on elliptic curve cryptography (ECC) to enhance patient medication safety. Our scheme can achieve security requirements and overcome various attacks existing in other schemes. In addition, our scheme has better performance in terms of computational cost and communication overhead. Therefore, the proposed scheme is well suitable for patient medication systems.

Regions of low density in the contrast-enhanced pituitary gland: normal and pathologic processes

Chambers, E.F.; Turski, P.A.; LaMasters, D.; Newton, T.H.

1982-01-01

The incidence of low-density regions in the contrast-enhanced pituitary gland and the possible causes of these regions were investigated by a retrospective review of computed tomographic (CT) scans of the head in 50 patients and autopsy specimens of the pituitary in 100 other patients. It was found that focal areas of low density within the contrast enhanced pituitary gland can be caused by various normal and pathologic conditions such as pituitary microadenomas, pars intermedia cysts, foci of metastasis, infarcts, epidermoid cysts, and abscesses. Although most focal low-density regions probably represent pituitary microadenomas, careful clinical correlation is needed to establish a diagnosis

2014-01-01

This paper examines the impact of climate change on food security of the population residing in the coastal area of Bangladesh. Based on multistage random sampling technique, a survey was conducted to collect socioeconomic and food datasets of the people affected by extreme climate events in the country. The study found that climate change caused food insecurity in the region; it led to greater dependence on pond and rain water for cooking food and water intake. Catastrophe due to extreme weather events adversely affected the livelihoods and level of income. The severe cyclonic storms, Sidr (November 2007) and Alia (May 2009) severely affected the vulnerable people of this region, especially the extremely poor. The study came out with several coping strategies to address adverse effects of climate change, including rehabilitation with income and employment generating activities and development training; alternative livelihood adaptation practices; access to subsidized inputs and credits; introduction of crop calendar; conservation of arable and fellow land; and innovation of saline-tolerant, heat-resistant, moderate water consuming and short-rotation crops for the coastal people.

[Objective]The experiment aimed to explore the influence of enhanced ultraviolet radiation-B on maize in arid regions of middle-high elevation for correct assessing the influence of enhanced ultraviolet radiation-B on maize and providing scientific reference to make proper countermeasures.[Method] The location test in field and lift lamp of UV-B were used to observe the changes of maize height , leaf area and number of green leaves under influences of different UV-B radiation. [Result]In arid regions of middle-high elevation, enhanced ultraviolet radiation-B could dwarf maize plant, decrease leaf area, decline number of green leaves and yield. The reason of decreasing leaf area was that enhanced ultraviolet radiation-B shortened leaf length and leaf width while the reason of declining yield was that yield components were all negatively influenced and with the increase of ultraviolet radiation-B, the yield declined dramatically.[Conclusion]The result of this experiment would be good for maize production in arid regions of middle-high elevation

The Potential Use of Agroforestry Community Gardens as a Sustainable Import-Substitution Strategy for Enhancing Food Security in Subarctic Ontario, Canada

Directory of Open Access Journals (Sweden)

Maren Oelbermann

2013-09-01

Full Text Available The high prevalence of food insecurity experienced by northern First Nations partially results from dependence on an expensive import-based food system that typically lacks nutritional quality and further displaces traditional food systems. In the present study, the feasibility of import substitution by Agroforestry Community Gardens (AFCGs as socio-ecologically and culturally sustainable means of enhancing food security was explored through a case study of Fort Albany First Nation in subarctic Ontario, Canada. Agroforestry is a diverse tree-crop agricultural system that has enhanced food security in the tropics and subtropics. Study sites were selected for long-term agroforestry research to compare Salix spp. (willow-dominated AFCG plots to a “no tree” control plot in Fort Albany. Initial soil and vegetative analysis revealed a high capacity for all sites to support mixed produce with noted modifications, as well as potential competitive and beneficial willow-crop interactions. It is anticipated that inclusion of willow trees will enhance the long-term productive capacity of the AFCG test plots. As an adaptable and dynamic system, AFCGs have potential to act as a more reliable local agrarian system and a refuge for culturally significant plants in high-latitude First Nation socio-ecological systems, which are particularly vulnerable to rapid cultural, climatic, and ecological change.

The Korean Peninsula Energy Development Organization : implications for Northeast Asian regional security co-operation?

International Nuclear Information System (INIS)

Snyder, S.

2000-01-01

This paper identifies opportunities for co-operation on regional development and security in the North Pacific region. The Korean Peninsula Energy Development Organization (KEDO) was created in 1993 during bilateral negotiations between the United States and the Democratic People's Republic of Korea (US-DPRK) over North Korea's alleged nuclear weapons program. The negotiations resulted in an agreement to freeze North Korea's known nuclear weapons program in return for the construction of two proliferation-resistant 100 MWe light water reactors (LWR) in North Korea, and the provision of 500,000 tons of heavy fuel oil per year until the completion of the LWR construction as compensation for lost energy production capacity resulting from the shutting down of North Korea's nuclear reactors. The author described the activities of KEDO and examined its internal dynamics. The unique circumstances that produced the Agreed Framework and KEDO in response to a major international crisis of the nuclear program in the DPRK were also highlighted along with the US-DPRK bilateral agreement and the multilateral institution involving the United States, South Korea, Japan and the European Union. Financial support from Australia and Canada was discussed along with the mechanism for engaging North Korea in regularized interaction and technical cooperation. It was concluded that KEDO's record of successes and failures is mixed. The energy security issue has been identified as an area that could result in conflict among Northeast Asian countries which are increasingly dependent on oil supplies from the Middle East. In response, numerous multilateral financing mechanisms have been developed to promote joint business opportunities that exploit natural gas resources in the Russian Far East to address Japanese, Korean and Chinese energy needs. 35 refs

The enhanced MR findings of hematopoietic regions in aplastic anemia were compared with those of spondylitis, metastatic vertebral tumors and hematologic neoplasms. The enhanced MR images showed hematopoietic regions to homogeneously enhance and occupy the margin of vertebral bodies, while spondylitis and metastatic tumors appeared as round, inhomogeneously enhancing lesions. MR images of leukemia and myelodysplastic syndrome showed homogeneous enhancement at the margins of vertebrae that was difficult to differentiate from hematopoietic regions. Enhanced MR images were useful in detecting the hematopoietic areas in marrow and differentiating them from spondylitis and metastatic tumors, although further experience is needed to distinguish between tumorous hyperplastic regions and benign hematopoietic regions in marrow.

Telecare medicine information systems (TMIS) present the platform to deliver clinical service door to door. The technological advances in mobile computing are enhancing the quality of healthcare and a user can access these services using its mobile device. However, user and Telecare system communicate via public channels in these online services which increase the security risk. Therefore, it is required to ensure that only authorized user is accessing the system and user is interacting with the correct system. The mutual authentication provides the way to achieve this. Although existing schemes are either vulnerable to attacks or they have higher computational cost while an scalable authentication scheme for mobile devices should be secure and efficient. Recently, Awasthi and Srivastava presented a biometric based authentication scheme for TMIS with nonce. Their scheme only requires the computation of the hash and XOR functions.pagebreak Thus, this scheme fits for TMIS. However, we observe that Awasthi and Srivastava's scheme does not achieve efficient password change phase. Moreover, their scheme does not resist off-line password guessing attack. Further, we propose an improvement of Awasthi and Srivastava's scheme with the aim to remove the drawbacks of their scheme.

Process Control Systems in the Chemical Industry: Safety vs. Security

Energy Technology Data Exchange (ETDEWEB)

Jeffrey Hahn; Thomas Anderson

2005-04-01

Traditionally, the primary focus of the chemical industry has been safety and productivity. However, recent threats to our nation’s critical infrastructure have prompted a tightening of security measures across many different industry sectors. Reducing vulnerabilities of control systems against physical and cyber attack is necessary to ensure the safety, security and effective functioning of these systems. The U.S. Department of Homeland Security has developed a strategy to secure these vulnerabilities. Crucial to this strategy is the Control Systems Security and Test Center (CSSTC) established to test and analyze control systems equipment. In addition, the CSSTC promotes a proactive, collaborative approach to increase industry's awareness of standards, products and processes that can enhance the security of control systems. This paper outlines measures that can be taken to enhance the cybersecurity of process control systems in the chemical sector.

The 3',5'-cyclic adenosine monophosphate (cAMP)-inducible enhancer of the human enkephaline gene is located within an imperfect palindrom of 23 base pairs. The authors have found that a 23-base-pair oligonucleotide duplex containing the enhancer undergoes a reversible conformational transition from the duplex to two individual hairpin structures each formed from one strand of the duplex. Each individual hairpin forms with mismatched base pairs, one containing two GT pairs and the other containing two AC pairs. The conformational transition is stabilized by proton transfer to the hairpin containing AC mismatched pairs. The unique physical and thermodynamic properties of the enkephalin enhancer DNA suggest a model in which DNA secondary structure within the enhancer region plays and active role incAMP-inducible activation of the human enkephalin gene via formation of cruciform structures

Chen, Wen; Chen, Xudong; Wang, Xiaogang

2015-01-01

We propose a method for security-enhanced phase encryption assisted by a nonlinear optical correlation via a sparse phase. Optical configurations are established based on a phase retrieval algorithm for embedding an input image and the secret data into phase-only masks. We found that when one or a few phase-only masks generated during data hiding are sparse, it is possible to integrate these sparse masks into those phase-only masks generated during the encoding of the input image. Synthesized phase-only masks are used for the recovery, and sparse distributions (i.e., binary maps) for generating the incomplete phase-only masks are considered as additional parameters for the recovery of secret data. It is difficult for unauthorized receivers to know that a useful phase has been sparsely distributed in the finally generated phase-only masks for secret-data recovery. Only when the secret data are correctly verified can the input image obtained with valid keys be claimed as targeted information. (paper)

Enhanced ATM Security using Biometric Authentication and Wavelet Based AES

2016-01-01

Full Text Available The traditional ATM terminal customer recognition systems rely only on bank cards, passwords and such identity verification methods are not perfect and functions are too single. Biometrics-based authentication offers several advantages over other authentication methods, there has been a significant surge in the use of biometrics for user authentication in recent years. This paper presents a highly secured ATM banking system using biometric authentication and wavelet based Advanced Encryption Standard (AES algorithm. Two levels of security are provided in this proposed design. Firstly we consider the security level at the client side by providing biometric authentication scheme along with a password of 4-digit long. Biometric authentication is achieved by considering the fingerprint image of the client. Secondly we ensure a secured communication link between the client machine to the bank server using an optimized energy efficient and wavelet based AES processor. The fingerprint image is the data for encryption process and 4-digit long password is the symmetric key for the encryption process. The performance of ATM machine depends on ultra-high-speed encryption, very low power consumption, and algorithmic integrity. To get a low power consuming and ultra-high speed encryption at the ATM machine, an optimized and wavelet based AES algorithm is proposed. In this system biometric and cryptography techniques are used together for personal identity authentication to improve the security level. The design of the wavelet based AES processor is simulated and the design of the energy efficient AES processor is simulated in Quartus-II software. Simulation results ensure its proper functionality. A comparison among other research works proves its superiority.

Triple Helix Model as an Efficient Mechanism of Food Security Provision in Regional Economic Entities and the Economic System as a Whole

2014-08-01

Full Text Available The leading countries of the world consider food security the important condition of internal political and social-economic stability of the state and its external independence. The topic of the article is crucial due to the fact that the problem of food security is rather complicated and multilevel and should be considered at different interrelated hierarchical levels. In this context the efficient model of food security is the result of the permanent dialogue between the representatives of the state government, business entities, social organizations and scientific institutions. The article justifies the fact that the model of innovation development, known as ‘the triple helix model’ should be applied at the modern stage of economic development as an efficient tool for the food security provision, which can be implemented in the activity of regional economic entities and the whole economic system of the Russian Federation.

Developing a secured social networking site using information security awareness techniques

Julius O. Okesola

2014-11-01

Full Text Available Background: Ever since social network sites (SNS became a global phenomenon in almost every industry, security has become a major concern to many SNS stakeholders. Several security techniques have been invented towards addressing SNS security, but information security awareness (ISA remains a critical point. Whilst very few users have used social circles and applications because of a lack of users’ awareness, the majority have found it difficult to determine the basis of categorising friends in a meaningful way for privacy and security policies settings. This has confirmed that technical control is just part of the security solutions and not necessarily a total solution. Changing human behaviour on SNSs is essential; hence the need for a privately enhanced ISA SNS. Objective: This article presented sOcialistOnline – a newly developed SNS, duly secured and platform independent with various ISA techniques fully implemented. Method: Following a detailed literature review of the related works, the SNS was developed on the basis of Object Oriented Programming (OOP approach, using PhP as the coding language with the MySQL database engine at the back end. Result: This study addressed the SNS requirements of privacy, security and services, and attributed them as the basis of architectural design for sOcialistOnline. SNS users are more aware of potential risk and the possible consequences of unsecured behaviours. Conclusion: ISA is focussed on the users who are often the greatest security risk on SNSs, regardless of technical securities implemented. Therefore SNSs are required to incorporate effective ISA into their platform and ensure users are motivated to embrace it.

Full Text Available As the land ecosystem provides the necessary basic material resources for human development, land ecological security (LES plays an increasingly important role in sustainable development. Given the degradation of land ecological security under rapid urbanization and the urgent LES requirements of urban populations, a comprehensive evaluation method, named Double Land Ecological Security (DLES, has been introduced with the city of Guangzhou, China, as a case study, which evaluates the LES in regional and unit scales for reasonable and specific urban planning. In the evaluation process with this method, we have combined the material security with the spiritual security that is inevitably associated with LES. Some new coefficients of land-security supply/demand distribution and technology contribution for LES evaluation have also been introduced for different spatial scales, including the regional and the unit scales. The results for Guangzhou indicated that, temporally, the LES supply indices were 0.77, 0.84 and 0.77 in 2000, 2006 and 2009 respectively, while LES demand indices for the city increased in 2000, 2006 and 2009 from 0.57 to 0.95, which made the LES level decreased slowly in this period. Spatially, at the regional scale, the urban land ecological security (ULES level decreased from 0.2 (marginal security to −0.18 (marginal insecurity as a whole; in unit scale, areas in the north and in parts of the east were relatively secure and the security area was shrinking with time, but the central and southern areas turned to be marginal insecurity, especially in 2006 and 2009. This study proposes that DLES evaluation should be conducted for targeted and efficient urban planning and management, which can reflect the LES level of study area in general and in detail.

TEC enhancements described in the present study have large magnitudes (≥25×10¹⁶ electrons/m² compared to the quiet-time values and long periods (≥120 min. The sequential manner of development and the propagation of these perturbations show that they are initiated at the northern region and propagate towards the southern region of Japan, with velocities >350 m/s. On 12 February 2000, remarkably high values of TEC and background content are observed at the southern region, compared to the north, because of the poleward expansion of the equatorial anomaly crest, which is characterized by strong latitudinal gradients near 35° N (26° N geomagnetically. When the TEC enhancements, initiating at the north, propagate through the region 39-34° N (30-25° N geomagnetically, they undergo transitions characterized by a severe decrease in amplitude of TEC enhancements. This may be due to their interaction with the higher background content of the expanded anomaly crest. However, at the low-latitude region, below 34° N, an increase in TEC is manifested as an enhanced ionization pattern (EIP. This could be due to the prompt penetration of the eastward electric field, which is evident from high values of the southward Interplanetary Magnetic Field component (IMF B_z and AE index. The TEC perturbations observed on the other storm days also exhibit similar transitions, characterized by a decreasing magnitude of the perturbation component, at the region around 39-34° N.

Food for Work Program and its Implications on Food Security: A Critical Review with a Practical Example from the Amhara Region, Ethiopia

Directory of Open Access Journals (Sweden)

2006-10-01

Full Text Available A systematic evaluation of food-for-work (FFW programs in Ethiopia is seriously lacking. Most of the few available reports indicate that these programs have reached very few achievements in terms of food security and reduction of poverty at large. As expressed by Holden et al. (2005, FFW programs are commonly aimed to produce or maintain potentially valuable public goods necessary to stimulate productivity and thus income growth. Natural resources management, like rural road construction, erosion control and afforestation of degraded lands can be mentioned as valuable measures which could stimulate productivity and agricultural growth. The poverty reduction and food security impact of food or cash for work activities are larger if they offer not only seasonal job opportunities to the rural community but also long term employment possibilities. This is more likely if the projects are regionally dispersed and combined with basic education. In the Ethiopian context, it was always questionable if the continuous boom in food aid (regardless of cash or food for work purposes was the solution for the long standing food insecurity and poverty crises in the country. The study discusses the efficiency of FFW programs that aimed to reduce rural poverty and ensure food security on the one hand, and the impact of the food aid on resource and time allocation of the participating households for own food production on the other. The study is based on a field research conducted at a FFW program project, in the Amhara region, Ethiopia run by the German Agency for Technical Cooperation (GTZ with the view of improving food security in the Amhara region, Ethiopia. A household theoretical model is used to analyze the sample data, whether FFW program may indeed reduce household food insecurity and/or has some crowding-out effects on labour allocation of participating households for own field production.

2011-03-01

Full Text Available Following the design of a conservation-based agricultural development strategy and food security strategy, the Tigray government has implemented different pro-poor development programs over the past years to address the problems of food security. This study attempts to investigate the effectiveness of government policy interventions at different scales addressed to improve food security. Food security both at the regional and district level was investigated by deriving food balance sheets for the period 2000-2008. An empirical analysis based on a logit model was also employed to analyze household level food security status. The results of the logit model reveal that government policy interventions such as water harvesting schemes, employment generation schemes, and promotion of technology adoption significantly contribute to a higher likelihood of household food security status. The findings of the food balance sheet also indicate that the region has made some impressive development gains in improving regional food self-sufficiency, indicating the importance of government interventions in improving food security both at the household and regional level.

Full Text Available The increasing popularity of biometrics and cryptography is driven by the widespread stipulation on information security. Abundant efforts have been made in developing successful methods in these areas in order to accomplish an enhanced level of information security. There are two dominant issues in information security enhancement. One is to defend the user ownership and control the access to information by authenticating an individual’s identity. The other is to make sure the privacy and integrity of information and to secure communication. Cryptography is the science of writing in secret code. Secret-key cryptography and public-key cryptography are the two most important cryptographic architectures. The security of a cryptographic system is reliant on the secrecy of the cryptographic key. Biometric authentication or simply biometrics refers to establishing automatic personal recognition based on the physical and behavioral characteristics of an individual (e.g. face, voice, fingerprint, gait, hand geometry, iris, gene, etc.. Biometrics offers superior security and easier than traditional identity authentication systems (based on passwords and cryptographic keys.Since biometrics characteristics are naturally related with a particular individual, making them insusceptible to being stolen, forgotten, lost or attached. This paper presents a survey on various techniques proposed earlier in developing an authentication system for ensuring individual’s information security by combining biometric characteristics of that particular individual and the cryptographic techniques. In addition, it provides some fundamental idea for future research that may help in eliminating the problems associated with the present authentication systems.

This paper addresses the legal and practical issues arising out of the design and implementation of a security-enhancement program for non power reactor nuclear facilities. The security enhancements discussed are derived from the commercial nuclear power industry's approach to security. The nuclear power industry's long and successful experience with protecting highly sensitive assets provides a wealth of information and lessons that should be examined by other industries contemplating security improvements, including, but not limited to facilities using or disposing of nuclear materials. This paper describes the nuclear industry's approach to security, the advantages and disadvantages of its constituent elements, and the legal issues that facilities will need to address when adopting some or all of these elements in the absence of statutory or regulatory requirements to do so

Full Text Available This article studies the development of innovative component for the region’s economic security. The hypothesis of the study is that in the context of globalization and development of network society, innovation is becoming one of the key elements ensuring the economic security of a region. We considered the relationship between the concepts of sustainable development and economic security. The authors show that currently, the economic security of the country directly depends on its place within the innovation chain. We substantiate that Russian Federation and its regions need to shift to the innovation development based on strengthening its own sources for long-term growth. The paper considers the basic theoretical and methodological problems in the formation of innovation component of the Russian regions’ economic security. We reveal the major essence and elements of the innovative component of the sustainable economic development of the region. The authors show that the formation of the innovative component of the region’s economic security demands the correlation of the strategy of regional innovation development and the production and technological type of territory. Additionally, this strategy should correlate with the desirable ways of production type transformation in the future, considering the trends of the world economy. We have highlighted the production and technological types of Russian regions as well as identified the features of relevant regional components for the innovation system of the Russian Federation to ensure sustainable development. The study defines the priority directions and goals for the development of economic security innovative component in the Russian regions. The authors’ calculations allowed to select a group of territorial subjects of the Russian Federation, which appear to be the most promising for the development of innovative activities for the elaboration of export-oriented high-tech industries

Raman Spectroscopy for Homeland Security Applications

Gregory Mogilevsky

2012-01-01

Full Text Available Raman spectroscopy is an analytical technique with vast applications in the homeland security and defense arenas. The Raman effect is defined by the inelastic interaction of the incident laser with the analyte molecule’s vibrational modes, which can be exploited to detect and identify chemicals in various environments and for the detection of hazards in the field, at checkpoints, or in a forensic laboratory with no contact with the substance. A major source of error that overwhelms the Raman signal is fluorescence caused by the background and the sample matrix. Novel methods are being developed to enhance the Raman signal’s sensitivity and to reduce the effects of fluorescence by altering how the hazard material interacts with its environment and the incident laser. Basic Raman techniques applicable to homeland security applications include conventional (off-resonance Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS, resonance Raman spectroscopy, and spatially or temporally offset Raman spectroscopy (SORS and TORS. Additional emerging Raman techniques, including remote Raman detection, Raman imaging, and Heterodyne imaging, are being developed to further enhance the Raman signal, mitigate fluorescence effects, and monitor hazards at a distance for use in homeland security and defense applications.

Enhanced antisunward convection and F region scintillations at mid-latitudes during storm onset

Millstone Hill radar observations over a wide span of latitudes detail the onset of 300 m/s antisunward (westward) convection at mid and low latitudes in the morning sector as a region of storm-enhanced sunward convection retreats poleward. Ring current observations reported by Lui et al. (1987) suggest that the magnetospheric shielding layer was coincident with the observed reversal between sunward and antisunward convection. A strong southward component of the F region neutral wind is observed at latitudes equatorward of the convection reversal. These observations are in agreement with the model of Spiro et al. (1988), who find that storm-enhanced neutrral winds at latitudes equatorward of the shielding layer can generate a long-lived perturbation electric field in the inner magnetosphere. The observations show the growth of the subauroral electric field as the shielding boundary moves poleward. They observe 136-MHz scintillations in both the auroral sunwarrd convection region and the region of subauroral antisunward convection when the convection electric fields exceed 5 mV/m
