In this paper, I have proposed a secure dynamic ID allocation protocol using mutual authentication on the RFID tag. Currently, there are many security protocols focused on the low-price RFID tag. The conventional low-price tags have limitation of computing power and rewritability of memory. The proposed secure dynamic ID allocation protocol targets to the high-performance RFID tags which have more powerful performance than conventional low-price tag by allocating a dynamic ID to RFID using mutual authentication based on symmetric encryption algorithm. This protocol can be used as a partial solution for ID tracing and forgery.

With the rapid development of information sharing through network, If system is exposed to various threatener and security incident are became a social problem. As a countermeasure, various security systems are been using such as IDS, Firewall, VPN etc.. But, expertise or expert is required to handle security system. In this paper, design and implementation of file access control module for secure operation system. The module, implemented in this paper, is based on Windows and has effect integrity and non-repudiation for a file.

As the development of information telecommunication technology and thus the information sharing and opening is accelerated, If system is exposed to various threatener and the avrious security incident is rasing its head with social problem. As countermeasure, to protect safely and prepare in the attack for a system from a be latent security threat, various security systems are been using such as IDS, Firewall, VPN etc.. But, expertise or expert is required to handle security system. The module, implemented in this paper, is based on Windows XP, like Linux and Unix, and has effect integrity and non-repudiation for a file.

Recent cyber attacks on South Korea, including hacking and viruses, are increasing significantly. To deal with the cyber invasion of cyber aggression, the Ministry of National Defense defined the necessary procedures for cyber security with guidelines for cyber security. In spite of, based on the analyses the cyber defense operations published, the number of violations are increasing. To address issues stated above, the safety check items should be reviewed and revised. This paper will revisit current safety check items and provide new guidelines to prevent cyber security breaches, which will provide more safe and efficient cyber environment.

The BcN is applying from public networks to local networks and each terminal step by step under supporting MIC(Ministry of Information and Communication Repoblic of Korea) until 2007. The architecture of network sorority should considers BcN environment and evolves to manage Ipv6 traffics. The next generation network security architecture can manage not only Ipv6 environment but also wire and wireless integrated network. We suggest the next generation network security architecture for Ipv6 environment and wire-wireless integrated network environment and verify the performance of the suggested architecture using network security scenario.

The development of the communication network and the other network method can generate serious social problems. So, it is highly required to control security of network. These problems related security will be developed and keep up to confront with anti-security field such as hacking, cracking. The way to preserve security from hacker or cracker without developing new cryptographic algorithm is keeping the state of anti-cryptanalysis in a prescribed time by means of extending key-length. In this paper, we proposed M3 algorithm for the reduced processing time in the montgomery multiplication part. Proposed M3 algorithm using the matrix function M(.) and lookup table perform optionally montgomery multiplication with repeated operation. In this result, modified repeated operation part produce 30% processing rate than existed montgomery multiplicator. The proposed montgomery multiplication structured unit array method in carry generated part and variable length multiplication for eliminating bottle neck effect with the RSA cryptosystem. Therefore, this proposed montgomery multiplier enforce the real time processing and prevent outer cracking.

This Study aims to propose a new information security governance model design method for streamlining security governance at national strategic level. The research method of this study is to diagnose our operational experience and to derive a new model design method. In the meantime, national information security activities were perceived to be focused on knowledge transfer, and motivation of activities and securing of executive power were weak. As a result, security blind spots and frequent occurrence of large security incidents have become unresolved challenges. National cyber security governance should be grouped together as a whole systematically from the upper policy to the lower level of performance under the responsibility of the national leader. Based on this approach, this study presented the comprehensive framework of Korean security governance model and embodied it into four architectural designs such as vision, goal, process, and performance, thus deriving the foundation for future national governance model design. Further research is needed to diagnose problems in life cycle flow, security policies based on environmental changes, and new frameworks in which all subjects participate.

The Protection Profile(PP) is a common security function and detailed statement of assurance requirements in a specific class of Information Technology security products such as firewall and smart card. The parts of TOE security environment in the PP have to be described about assumption, treat and security policy through analyzing purpose of TOE. In this paper, we present a new security policy derivation among TOE security environment parts in the PP. Our survey guides the organizational security policy statements in CC scheme through collected and analyzed hundred of real policy statements from certified and published real PPs and CC Toolbox/PKB that is included security policy statements for DoD. From the result of the survey, we present a new generic organizational policy statements list and propose a organizational security policy derivation method by using the list.
