임베디드 시스템은 주로 처리된 정보를 관리하는 서버를 가지고 있다. 임베디드 시스템 대부분이 많은 양의 데이터를 적재 할 수 없기 때문에 별도로 처리된 정보들을 관리하는 서버가 필요하다. 이런 서버와 임베디드 시스템을 직접 연결하거나 요즘에는 USN을 이용하여 연결하기도 한다. 이런 임베디드 시스템에 다수의 사용자가 접근하여 제어가 가능하도록 하기 위해서 임베디드 미니 웹서버의 역할이 매우 중요하다. 임베디드 미니 웹서의 사용자 접근에는 여러 방법이 있다. 일반적인 웹서버 방법 중에 하나인 ID와 비밀번호를 이용한 로그인 방법이나 IP주소를 구분하는 방법 등이 있다. 하지만 이런 방법들은 완벽한 사용자의 고유성을 보장 할 수 없다. ID와 비밀번호를 도용할 수 있으며, IP주소를 구분하는 것도 아주 한정적인 사용자 관리에 불과하다. 이런 단점을 좀 더 보완하고자 접근 사용자가 RFID리더를 가지고 자신만의 RFID Tag를 읽힘으로써 사용자의 고유성을 높일 수 있다. RFID를 이용한 임베디드 미니 웹서버를 접근하는 시스템을 설계한다.

콘텐츠의 다양화로 인해 콘텐츠의 관리를 위해 CMS(contents Management System)가 다양하게 운영되고 있다. 현재 CMS들은 단지 소속회원들을 기반으로 DRM기술을 적용하여 콘텐츠 저작권을 보호하고 있다. 따라서 콘텐츠의 글로벌 사용이 제한되고 상호운용이 불가능하고 콘텐츠의 원천적 저작권보호가 불가능하다. 따라서 이 논문에서는 저작권 보호를 위하여 공개키 기반의 라이선스관리 모듈을 설계하였으며 이를 기반으로 콘텐트 암호화하는 패키저 모듈, 암호화된 콘텐트를 복호화하는 언 패키저 모듈, 콘텐트 공유서버 및 클라이언트 모듈을 설계하였다. 이기종간의 CMS는 트랜젝션 서버를 통해 통합 메타데이터를 공유하며 통합 CMS를 운영하여 다양한 콘텐츠를 다양한 CMS에서도 활용 가능하도록 제안하였으며 웹 콘텐츠 인증코드를 이용한 DRM 기술을 기반으로 콘텐츠 사용 제한 및 저작권 보호를 지원한다.

RSA is the most widely used public key algorithms. Payment via the SSL communications, and user authentication using RSA secure shopping mall that can protect the user's valuable information in the process of building. SSL-based electronic signature technology and encryption protocols for this technology are electronic documents are delivered to the other party through a separate encryption process, the information sender to enter information on a web browser (user) and the recipient (the Web server of the site Manager), except you will not be able to decrypt the contents. Therefore, the information is encrypted during the transfer of electronic documents even if hackers trying to Sniffing because its contents can never understand. Of internet shopping mall in the user authentication 'and' Communications' SSL secure shopping mall built with the goal of the methodology are presented.

Personal registration number has been used as a means of personal identification on existing internet. However, its use on internet sites has become a major factor increasing danger of leaking of personal information. Presently, the government recommends i-PIN to minimize the collection of personal registration numbers and leaking of personal information on internet. Original purpose of i-PIN is to recognize persons by its virtual number of 13 digits instead of using personal registration number on internet websites. These days, i-PIN continues to be used increasingly as a form of certification. This study seeks to explore software service methodology of using i-PIN as a form of certification on internet websites and examples in which its other forms of self certification are used than existing i-PIN services.

With the popularization of the Internet and smartphone uses, people in the modern era are living in a multi-channel environment in which they access the information system freely through various methods and media. In the process of utilizing such services, users must authenticate themselves, the typical of which is ID & password authentication. It is considered the most convenient method as it can be authenticated only through the keyboard after remembering its own credentials. On the other hand, modern web services only allow passwords to be set with high complexity by different combinations. Passwords consisting of these complex strings also increase proportionally, since the more services users want to use, the more user authentication information they need to remember is recommended periodically to prevent personal information leakage. It is difficult for the blind, the disabled, or the elderly to remember the authentication information of users with such high entropy values and to use it through keyboard input. Therefore, this paper proposes a user authentication method using Google Assistant, MFCC and DTW algorithms and speaker authentication to provide the handicapped users with an easy user authentication method in the login process.

The development of the security solutions that can provide a variety of security services is needed urgently. For development of the security solutions, analysis of international standard security technology is the key. In this paper, international organizations' standardization(ISO/IEC JTC1 SC27, ITU-T SG-17, IETF Security Area, etc.) and the current trend of the standard security technology are mainly analyzed. The core of the latest security technology(Application Bridging, DNS-based Authentication, HTTP Authentication, IP Security, Javascript Security, Authentication Technology Next Generation, Managed Incident, Web Authorization Protocol, Security Automation, Transport Layer Security, etc.) is analyzed focusing on 18 working groups of the IETF.

Since the facilities for the remote users tend to be deployed in distributed manner, authentication schemes for multi-server communication settings, which provide various web services, are required for real-world applications. A typical way to authenticate a remote user relies on password authentication mostly. However, this method is vulnerable to attacks and inconvenient as the system requires users to maintain different identities and corresponding passwords. On the other hand, the user can make use of a single password for all servers, but she may be exposed to variants of malicious attacks. In this paper, we propose an efficient and secure authentication scheme based on a brokered authentication along with smart-cards in multi-server environment. Further we show that our scheme is secure against possible attacks and analyze its performance with respect to communication and computational cost.

Current SSO has focused on authenticated integration between inter systems in a domain.On the contrary, becasuse SSO using SAML can support integration between different domains, once it is used in RIA, we can expect highly synergic effect. However, because researches on SSO using SAML are mainly those on authenticated information exchange between servers, a special research is needed in order to be applied in RIA environment, which conducts numerous managements in client. This study proposes architecture and explain a practice structure in order to apply SAML to RIA. Also, this study has embodied the proposed architecture and applied it on DWR, which is used mostly as Data communication framework of RIA, and verified the useablity of this architecture.

Internet becomes absolutely necessary tools due to rapid progress of information technology. Educational correspondence abount an age of information demand is a education focused on a learner and remote education based on information technology. Internal and external standardization working is accelerated and recently XML security studies are activated using XML which is next generation web standard document format. But using these are main contents that users have to pay about Certification service to get CA certificate from 2004 me. This paper propose multiplex Certification remote education agent system using XML digital signature to satisfy security requirement.
