본 논문에서는 무선 인터넷 환경에서 CHAP 인증 기법을 이용한 로밍 서비스 지원방법을 기술한다. 이를 위해 특별히 GPRS 망으로 이동한 이동 ISP 망 가입자가 자신의 홈 ISP 망을 접속하여 인증을 받기 위한 기법을 제시한다. 또 이동 ISP 망 가입자의 단말에서 정의되어야 할 인증 메시지 구조와 GPRS 망 게이트웨이에서 구현 될 메시지 구조를 제시한다. 아울러 GGSN과 ISP 망간의 인증 메시지 구조를 정의하며 이들 제안된 내용에 대해 시험 환경 구축을 통해 실제 시뮬레이션 결과를 보였다.

Hospital medical services are making great efforts to provide prompt medical services to patients or improve the quality of medical services by convergence patient's healthcare information. However, recent research suggests problems about safety and efficiency when trying to transmit patient's healthcare information to hospital server via radio and wireless. In this paper, we propose a color model - based patient authentication key establishment protocol method to securely transmit patient healthcare information. The proposed method extracts randomly three color information used in the color model and vectorizes the extracted arbitrary information to obtain the key information required for user authentication as the sum of orthogonal vectors to improve the efficiency. In addition, the proposed method can securely generate key information used for user authentication without using an additional encryption algorithm. In performance evaluation result, proposed method shows that the server processing time of the sensed information is 8.1% higher than the existing method and 7.7% lower than the existing method.

In ubiquitous environment the authentication protocol design for RFID security is studied to protect user privacy in RFID system. The XOR-based approach of RFID security is implemented inexpensively and simply. However because of using same security informations, ones of tag is disclosed easily. In this paper, we enhance the previous XOR-based authentication protocol using a circular shift operation.

Intellgent Vehles network capabilities can cause a lots of security issues such as data hacking, privacy violation, location tracking and so on. Some possibilities which raise a breakdown or accident by hacking vehicle operation data are on the increase. In this paper, we propose a security module which has user authentication and encryption functionalities and can be used for vehicle network system.

An integrated medical information system should be equipped for the activation of u-healthcare service. In addition, the integrated medical information system should be based on an authentication system to be implemented in a safe environment. However, several requirements are being developed yet. In this paper, biometric authentication system will be designed and proposed for u-healthcare services for the integrated medical information system to go one step further.

As the importance of information security grows, the demand of professionals in information security field is continuing to increase. In developing as information security professionals, however, there are practical problems to be solved in advance. This study defines the body of essential knowledge(EBK) for information security professional development; on the other hand, this study suggests a education program as a multidisciplinary major based on the EBK.

Current IEEE 802.11 standard is very vulnerable that between the AP and STA authentication and security mechanisms is widely known. Therefore, IEEE has proposed security architecture RSN (Robust Security Network) for 802.11. RSN is used the access control, authentication, and key management based on the IEEE 802.1X standard. In this paper, IEEE 802.1X or 802.11 a combination of several models proposed for the vulnerability, and session hijacking or MiM (Man-in the-Middle) attacks to respond, the authentication mechanism Was designed to the access control between the STA and the AP.

Phishing is an attack to theft an user's identity by masquerading the user or the device. The number of phishing victims are sharply increased due to wide spread use of smart phones and messenger programs. Smart phones can operate various wi-fi based apps besides typical voice call and SMS functions. Generally, the messenger program such as Kakao Talk or Nate On is consisted of client and server functions. Thus, the authentication between the client and the server is essential to communicate securely. In this paper, we propose the messenger authentication protocol safe against smart phone phishing. To protect communications among clients, the proposed method provides message encryption and authentication functions.
