ARIA and the Advanced Encryption Standard (AES) are next generation standard block cipher algorithms of Korea and the US, respectively. This letter presents an area-efficient unified hardware architecture of ARIA and AES. Both algorithms have 128-bit substitution permutation network (SPN) structures, and their substitution and permutation layers could be efficiently merged. Therefore, we propose a 128-bit processor architecture with resource sharing, which is capable of processing ARIA and AES. This is the first architecture which supports both algorithms. Furthermore, it requires only 19,056 logic gates and encrypts data at 720 Mbps and 1,047 Mbps for ARIA and AES, respectively.

In this paper, an Information Security protocol in LLC/MAC Layer Architecture is discussed. This paper examines the security Vulnerability and threats, the security Service required to protect these threats, and architectural considerations of security protocol in IEEE 802 LAN architecture. To provide an Information security service, an information security protocol(SP2 : Security Protocol 2) PDU construction with LLC/MAC service primitives is suggested. To construct the SP2 protocol, the ECB, CBC mode of DES algorithm and DAA(Data Authentication Algorithm) of FIPS is used. The SP2 protocol suggested in this paper provides data origin authentication, data confidentiality, data integrity service.

In our country security industry biz model analysis methodology fragmentary theory exists, but it is hard to find a comprehensive analysis methodology. Biz model analysis IT companies the external factors and internal factors to integrate the information gathered about the comprehensive analysis of the development of an information system are required. Information support system early in the software architecture of the system design decisions early decision as the design, development, testing, maintenance, has a lasting impact on the project as a guideline in the development of a framework of design abstraction. BMO evaluation support information systems architecture designs system purposes. The mission must support the execution. Information system stakeholders to determine the mission and the environment. All information systems architecture shall have architecture. Technology architecture should be documented with each other can be used. Determine the architecture based architecture descriptions are presented.

Internet attack incidents have steadily increased along with the increase in Internet users. To protect systems and networks from these attacks, advanced security systems have been developed. Now that these security systems are operating, their successful management is more important than the purchase and establishment of new information security systems. The acquisition of good systems is ineffective and financially wasteful unless they are managed properly. Adequate management policy has recently become the focus of users. In other words, for companies and educational institutions with their domains, capital expenses are enormous to bear, and good security staffs are difficult to find, for which reasons outsourcing vendors or Managed Security Service Providers (MSSPs) that manage and operate the information security systems of certain domains become very appealing. Today, customers expect ISPs to perform MSSP services that used to be carried out by the security companies. This document presents the role and necessity of ISPs as MSSPs.

The widespread use of the Internet brings about the issue regarding intellectual property and copyright. This paper describes DRM (Digital Rights Management) technologies and their related issues. Current approaches on DRM architecture are examined first. Based on the review, we discuss some security issues that would be essential to design security mood and architecture appropriate for DRM. Having these security issues in mind, we propose a new approach on DRM security architecture, based on our trust model.

현재 네트워크는 유 무선이 통합되는 차세대 네트워크(NGN), 유비쿼터스 시대로 발전하고 있다. 현대인의 네트워크에 대한 의존도가 커질수록, 네트워크 취약점을 악용한 사이버상의 위협과 새로운 공격 유형이 급증하고 있다. 보다 안전하고 신뢰할 수 있는 네트워크 환경을 위해 다양한 보안 제품들이 등장하고 서로의 기능들을 통합하여 더 나은 보안 서비스를 제공하고자 노력하고 있으나, 기존의 대표적인 보안 제품들로는 그 한계가 있다. 따라서 네트워크 자체가 취약점과 공격을 받더라도 지속적으로 서비스를 제공할 수 있고, 빠른 보안 업데이트를 통해 네트워크 자체의 붕괴를 미연에 예방 가능한 새로운 네트워크 보안 구조가 요구된다. 본 논문에서는 차세대 네트워크 발전 방향에 적합한 네트워크 보안 구조를 제안하고, 제안하는 구조에서 네트워크 보안 시나리오를 제시하여 검증한다.

The increasing demand of users for various wireless communication services has lead to the development with uniting co-existence of different and wireless networks. Each one of the these wireless networks has its own unique characteristics, as compared to other networks. An integrated security mechanism is one of the key issue in the open wireless network. To realize overall security mechanism in open wireless architecture, we should provide practical workable framework for the realization of the integrated security challenges. In this paper, we analysed integrated security platform and considerations based on the security concept.

Web-based health information provides a lot of conveniences, however the security vulnerabilities that appear in the network environment without the risk of exposure in the use of information are growing. Web-based medical information security issues when accessing only the technology advances, without attempting to seek a safe methodology are to increase the threat element. So it is required. to take advantage of web-based information security measures as a web-based access control security mechanism-based design. This paper is based on software architecture, design, ideas and health information systems were designed based on access control security mechanism. The methodologies are to derive a new design procedure, to design architecture and algorithms that make the mechanism functio n. To accomplish this goal, web-based access control for multiple patient information architecture infrastructures is needed. For this software framework to derive features that make the mechanism was derived based on the structure. The proposed system utilizes medical information, medical information when designing an application user retrieves data in real time, while ensuring integration of encrypted information under the access control algorithms, ensuring the safety management system design.

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.
