This paper analyzed the SCMS and pilot policy, which is pursued by the U.S. government in connected vehicles. SCMS ensures authentication, integrity, privacy and interoperability. The SCMS Support Committee of U.S. government has established the National Unit SCMS and is responsible for system-wide control. Of course, it introduces security policy, procedures and training programs making. In this paper, the need for SCMS to be applied to C-ITS was discussed. The structure of the SCMS was analyzed and the U.S. government's filot policy for connected vehicles was discussed. The discussion of the need for SCMS highlighted the importance of the role and responsibilities of SCMS between vehicles and vehicles. The security certificate management system looked at the structure and analyzed the type of certificate used in the vehicle or road side unit (RSU). The functions and characteristics of the certificates were reviewed. In addition, the functions of basic safety messages were analyzed with consideration of the detection and warning functions of abnormal behavior in SCMS. Finally, the status of the pilot project for connected vehicles currently being pursued by the U.S. government was analyzed. In addition to the environment used for the test, the relevant messages were also discussed. We also looked at some of the issues that arise in the course of the pilot project.

This paper is a study on the industrial security specialists of organizations in possession of industrial technology and their compliance motivations towards security policies. The focus is on organizational justice, organizational attachment and empowerment based on our hypothesis that compliance motivations are shaped, not only by the organization itself but, also by the attitude and principle of the organization's members. The objective is to propose a direction for administrative security policy to increase prevention of industrial technology leakage by identifying the factors' significance through hypothesis testing and thereafter investigating the influencing relationship. Survey questionnaires are collected from the participants of a regular educational program provided by the Korean Association for Industrial Technology Security (KAITS) and analyzed using SPSS 21.0 and AMOS 21.0 software. Through various statistical analyses, following results are acquired. First, procedural fairness and organizational attachment are found to motivate security supervisors to comply with security policies. Particularly, the relationship between procedural fairness and compliance motivations towards security policies is fully mediated by organizational attachment, suggesting that improved fairness at the organizational level will lead to an increase in organizational attachment, which will encourage the individuals to comply with security policies. Additionally, empowerment of the individuals in organizations partially mediates the relationship between procedural fairness and organizational attachment, confirming that procedural fairness empowers each individual and increases his organizational attachment. Specifically, in order to maximize compliance of security policies, businesses should demonstrate procedural fairness when compensating their employees for their work to empower them and increase their organizational attachment, which can increase their will to comply with existing security policies. This research provides insights into how to encourage security supervisors to comply with security policies by increasing their empowerment and organizational attachment.

Modern Bulgarian nationalists aspired towards incorporating the self-identified Bulgarian lands into the Bulgarian state. The Treaty of San Stefano ending the Russo-Turkish War of 1877-78 tantalizingly achieved these so-called national ideals. Great Power diplomacy quickly diminished Bulgaria's borders and international legal status with the 1878 Treaty of Berlin, exacerbating nationalist grievances. Bulgaria would expand vast resources to restore the San Stefano borders until Balkan Communist authoritarian regimes eventually suppressed the Macedonian issue as a foreign policy subject. Sofia's policy towards its neighbor has been overdetermined by the efforts of successive Bulgarian governments to institutionalize post-communist Bulgaria's own national identity. Bulgaria's integration into so-called Euro-Atlantic structures, i.e., NATO and the EU, had been the primary strategic objective of the Bulgarian authorities since the end of the Zhivkov regime. North Atlantic community security policy aims in response to the earliest post-Cold War foreign policy crises in the Western Balkans framed the parameters of Bulgarian diplomacy. The stabilization of FYROM in 2001, followed by Bulgaria's 2007 EU accession, led to Bulgarian nationalist values become more salient in Bulgarian politics and foreign policy. Sofia-Skopje relations are a test case for the effects of Europeanization on interdependent Balkan ethno-sectarian nationalisms and state territorial institutional development.

The acceptance of smartphone applications in the learning field is one of the most significant challenges for higher education institutions in Saudi Arabia. These institutions serve large and varied sectors of society and have a tremendous impact on the knowledge gained by student segments at various ages. M-learning is of great importance because it provides access to learning through a wide range of mobile networks and allows students to learn at any time and in any place. There is a lack of quality requirements for M-learning applications in Saudi societies partly because of mandates for high levels of privacy and gender segregation in education (Garg, 2013; Sarrab et al., 2014). According to the Saudi Arabian education ministry policy, gender segregation in education reflects the country's religious and traditional values (Ministry of Education, 2013, No. 155). The opportunity of many applications would help the Saudi target audience more easily accept M-learning applications and expand their knowledge while maintaining government policy related to religious values and gender segregation in the educational environment. In addition, students can share information through the online framework without breaking religious restrictions. This study uses a quantitative perspective to focus on defining the technical aspects and learning requirements for distributing knowledge among students within the digital environment. Additionally, the framework of the unified theory of acceptance and use of technology (UTAUT) is used to modify new constructs, called application quality requirements, that consist of quality requirements for systems, information, and interfaces.

As new information technology emerges, companies are introducing an Enterprise Security Management system to cope with new security threats, reducing redundant investments and waste of resources and counteracting security threats. Therefore, it is necessary to construct a security evaluation metric based on related standards to demonstrate that the Enterprise Security Management(ESM) System meets security. Therefore, in order to construct a metric for evaluating the security of the ESM, this study analyzed the security quality related requirements of the ESM and constructed a metric for measuring the degree of satisfaction. This metric provides synergies through the unification of security assessments that comply with ISO/IEC 15408 and ISO/IEC 25000 standards. It is expected that the evaluation model of the security quality level of ESM will be established and the evaluation method of ESM will be standardized in the future.

Cloud computing has emerged as perhaps the hottest development in information technology at present. This new computing technology requires that the users ensure that their infrastructure is safety and that their data and applications are protected. In addition, the customer must ensure that the provider has taken the proper security measures to protect their information. In order to achieve fine-grained and flexible access control for cloud computing, a new construction of hierarchical attribute-based encryption(HABE) with Ciphertext-Policy is proposed in this paper. The proposed scheme inherits flexibility and delegation of hierarchical identity-based cryptography, and achieves scalability due to the hierarchical structure. The new scheme has constant size ciphertexts since it consists of two group elements. In addition, the security of the new construction is achieved in the standard model which avoids the potential defects in the existing works. Under the decision bilinear Diffie-Hellman exponent assumption, the proposed scheme is provable security against Chosen-plaintext Attack(CPA). Furthermore, we also show the proposed scheme can be transferred to a CCA(Chosen-ciphertext Attack) secure scheme.

High expectations are posed on the blockchain-based internet of things (IoT), in which IoT and blockchain technology is combined to obtain trust in the Internet, where trust appears impossible to obtain. However, applications of current blockchain-based IoT technology to real-world scenarios appears to be significantly more difficult owing to limitations regarding scalability and security. In this paper, the difficulties to implement blockchain networking technologies for IoT and digital businesses are investigated and practical solutions such as sharding, off-chain, de-idetification and P2P crypto-currency exchange are explored. In further work, a blockchain platform for IoTs which provides scalability and security will be implemented according to this research results, and compared with conventional blockchain platforms.

We are confronted by increase in old people due to the improvement in medical science, public hygiene and socioeconimic status in 20th century. But our medical security system for old people dees not meet the need for medical service of old people. Current medical insurance system restricts term and extent in allowance although the characteristics of the disease of the aged people need medical care of Bong duration and high cost. And in the medicaid system the speciality of the aged people is not recognized and the budget of the government is scanty. In addition many old people to our country are in economic distress due to low income. But the government authority does not give sufficient consideration for eld people in law, policy and budget. To improve social security system for old people it is necessary to increase the budget for the security of old people, to enhance the traditional respect for the aged, to improve medical security system by improving the accessibility to medical service and by expanding the allowance of medical insurance, and to expand the public welfare institutions. And these are roles for all the family. the society and the nation as well as the aged people themselves.

The In the 4^th industrial revolution, cyber space will evolve into hyper-connectivity, super-convergence, and super-intelligence due to the development of advanced information and communication technologies, which will connect the nation's core infrastructure into a single network. As applying the 4^th industrial revolution technology to the cyber attack technique, it is evolving in an intelligent and sophisticate method. In order to response intelligent cyber attacks, it is difficult to guarantee self-defense in cyberspace by policy-oriented, preplanned-centric and hierarchical cyber response strategies. Therefore, this research aims to propose a situation-flexible & action-oriented cyber response mechanism that can respond flexibly by selecting the most optimal smart security solution according to changes in the cyber attack steps. The proposed cyber response mechanism operates the smart security solutions according to the action-oriented detailed strategies. In addition, artificial intelligence-based decision-making systems are used to select the smart security technology with the best responsiveness.
