Application contents verifications and operations are essential for using a secure smart phone environment. In the existing smartphone environment, application verification was performed only in the application company and users has direct management application. However these application verification and management practices have been caused by a variety of security vulnerabilities. Therefore, we will analyze the security vulnerabilities in the existing methods and then we propose an application contents management of smart phone using pre-qualification method.

Many researches have proposed key management schemes for Smartgrid System. However, previous studies lack the proper considerations for availability and device security. In this paper, we build up cryptographic security improvement for robust Smartgrid Systems. In addition, we propose a public-key management and hash function architecture for robust Smartgrid Systems which supports reduces the number of key and Secure Device in AMI network environments.

지구 온난화와 같은 환경 문제와 에너지 소비 증가에 따른 에너지 확보의 어려움에 많은 국가들이 어려움을 격고 있다. 이러한 에너지 확보 문제와 지구 온난화라는 문제를 해결할 수 있는 방법으로 제안된 것이 스마트 그리드 (Smart Grid) 이다. 스마트 그리드란 기존 전력망에 IT기술을 접목하여 공급자와 소비자가 양방향으로 실시간 전력정보를 교환함으로써 에너지 효율을 최적화하는 전력망이다. 기존의 폐쇄이던 전력망이 다양한 이해당사자가 참여하는 상호운용성이 보장되는 개방형 구조를 가지게 됨으로써 이에 대한 보안 기술 개발이 시급한 상태이다. 따라서 본고에서는 이러한 스마트 그리드 환경에 대해 설명하고 이러한 환경에서의 안전한 키 관리 기술에 대한 동향을 살펴본다.

RFID technology is already used in the various application fields such as identification card, traffic card and etc. Many RFID application systems using UHF have been developed in the field of asset management, logistics and security. Because a human being can make mistakes, we need the system that can efficiently manage the special assets such as small arms, jewelry and medicine and can monitor them in real time. In this paper, we proposed a special assets management system to keep assets in safe custody, to monitor their safety status in real time and to manage distribution channels and history of those assets. The developed system is called Smart Cabinet because it has cabinet's form. Smart Cabinet integrates such technologies as RFID, smart card, fingerprint recognition, several sensors and LCD display in order to provide the functions for special asset management. Those functions include condition monitoring of assets, traceability management, distribution channels and security logs, which are to interact with a management server. The article demonstrated the potentiality of RFID by presenting special asset management solutions dedicated to guns and medicine management, and also showed the effectiveness and possibility of those solutions.

It is necessary to improve the self-management ability of Hazard Analysis Critical Control Point (HACCP) certified companies and intensive management for companies with insufficient management. In addition, the efficiency and convenience of HACCP operation should be improved by expanding and distributing smart HACCP. In this way, it is the direction that HACCP in Korea should go forward to continuously discover and expand the field of application with the improving and smartening the HACCP system.

Smart Grid is the next-generation intelligent power grid that maximizes energy efficiency with the convergence of IT technologies and the existing power grid. It enables consumers to check power rates in real time for active power consumption. It also enables suppliers to measure their expected power generation load, which stabilizes the operation of the power system. However, there are high possibility that various kinds of security threats such as data exposure, data theft, and privacy invasion may occur in interactive communication with intelligent devices. Therefore, to establish a secure environment for responding to such security threat with the smart grid, the key management technique, which is the core of the development of a security mechanism, is required. Using a hash chain, this paper suggests a group key management mechanism that is efficiently applicable to the smart grid environment with its hierarchical structure, and analyzes the security and efficiency of the suggested group key management framework.

These days, smart card management system(SCMS) have been broadly used for security conformability, efficiency of issuance management, key management and expert management in the smart card market. SCMS is composed of card management, issuance management, key management, application management, and issuers management systems. SCMS enables card issuers from banks, credit card companies, and telecommunications companies to provide these cards to card users. And then SCMS enables card users to download new programs to chips for use of these cards successively and provide related smart card data in safety and efficiency. In this paper, we propose a framework for security assessment and an efficient method for security improvement through fault analysis which is more effective.
