Abstract: 본 발명은 RADIUS 또는 다이아미터와 같은 서로 다른 인증 프로토콜을 사용하는 무선랜망 또는 휴대 인터넷망간이 적절하게 인증 처리를 수행하는 방법 및 이 방법을 수행할 수 있는 라우터를 제공한다.
본 발명에 따른 인증 처리 방법은, 방문망에 접속된 사용자의 이동단말로부터 인증을 요청하는 인증요청메시지를 수신하여 인증요청메시지의 유형이 핵심망에서 정의된 메시지의 유형과 동일한지 여부를 판단한다. 그 판단 결과, 동일하지 않는 경우, 인증요청메시지를 핵심망에서 처리될 수 있는 메시지로 변환하고, 이 변환된 메시지를 핵심망 내의 인증서버로 라우팅하고, 동일한 경우, 인증요청메시지를 기초로 사용자의 네트워크접근식별자를 분석하여 이동단말의 홈망을 확인하고 이 홈망의 인증서버가 수신할 수 있는 인증처리메시지를 생성하고, 인증처리메시지가 홈망의 인증서버로 전송되도록 라우팅한다.-

Abstract: PURPOSE: A handoff method between DSs(Distribution Systems) in a wireless LAN is provided to transmit user information to a mobile AP by using an IAPP(Inter-Access Point Protocol) and a message of a mobile IP, thereby preventing a new authentication procedure and minimizing user data loss. CONSTITUTION: A mobile station performs a re-association process(301). A new AP transmits an access request message to a local RADIUS server(LR1)(302). The local RADIUS server(LR1) returns an access accept message to an AP(303). The AP performs a TCP connection setup with a received FA(Foreign Agent)(304). The new AP transmits a send-security-block packet(307), receives an acknowledgement-security-block packet(308), and transmits a move-notify message to the FA(309). A wideband RADIUS server returns an IP address and security information as an access accept message(311). The FA transmits a binding update message(312). If security relation information does not exist, the FA transmits an access request message(313), receives an access response message from the wideband RADIUS server(314), and transmits an access request message to the local RADIUS server(LR1)(315). The local RADIUS server(LR1) returns an access response message(316). If a TCP connection setup is not performed, a TCP connection setup is carried out between a previous AP and a previous FA(317). The previous FA transmits a send-security-block packet(320), and transmits a move-notify message to the previous AP(322). The new AP returns a re-association response message to the mobile station(326). A packet is transmitted to the new FA(329), and is reversely capsulated(330). The new FA reversely capsulates the received packet, and transmits the packet to the new AP(332).

Abstract: PURPOSE: A data encoding method is provided to encode data efficiently in view of stability such as a data security and a subscriber authentication, to carry out a high speed of operation, and to allow to apply in a radio communication environment. CONSTITUTION: In a data encoding method of a radio communication environment, messages are input, and the messages are divided into two and the divided messages are input to a left block and a right block respectively. A bit stream input to the right block is input to an F function and the left block of the next round. After a bit exclusive OR operation of the bit stream in which the F function is input to the bit stream of the right block and the bit stream input to the left block is carried out, the result values are input to the right block of the next round. After the above operations are carried out repeatedly by a described times, the result values are transposed and the finally encoded stream is output.
