Title (EN) METHOD AND APPARATUS FOR SECURITY OF MEDIUM INDEPENDENT HANDOVER MESSAGE TRANSMISSION
(FR) PROCÉDÉ ET DISPOSITIF POUR LA TRANSMISSION SÛRE DE MESSAGES DE TRANSFERT INDÉPENDANT DU SUPPORT
(KO) 매체 독립 핸드 오버 메시지 전송의 보안 방법 및 장치
Abstract:
(EN) The present invention relates to a method for security of medium independent handover message transmission and an apparatus for same, comprising: a master session key generation step wherein a terminal performs an authentication procedure with an access router to generate a master session key, a key transmission step wherein the access router transmits the master session key generated and address information of the terminal to an information server, an information server key generation step wherein the information server uses the master session key that has been received and the address information of the terminal to generate an information server key to be used upon sending and receiving a message to and from the terminal, and a security channel formation step wherein the terminal and the information server use the information server key that has been generated to form a security channel. According to the invention, a key formed at a tier 2 is used at a tier 3 of an MIH authentication step and a security key is not redundantly generated, so that security procedures may be performed speedily.
(FR) L'invention concerne un procédé pour la transmission sûre d'un message de transfert indépendant du support et un dispositif correspondant. Le procédé selon l'invention comprend une étape de génération de clé de session maître dans laquelle un terminal effectue une procédure d'authentification auprès d'un routeur d'accès pour générer une clé de session maître, une étape de transmission de clé dans laquelle le routeur d'accès transmet à un serveur d'informations la clé de session maître générée et les données d'adresse du terminal, une étape de génération de clé de serveur d'informations dans laquelle le serveur d'informations utilise la clé de session maître et les données d'adresse du terminal reçues pour générer une clé de serveur d'informations à utiliser lors de l'envoi d'un message au terminal et de la réception d'un message en provenance du terminal, ainsi qu'une étape de formation de canal de sécurité dans laquelle le terminal et le serveur d'informations utilisent la clé de serveur d'informations qui a été générée pour former un canal de sécurité. Selon l'invention, une clé formée à un niveau 2 est utilisée à un niveau 3 d'une étape d'authentification du transfert indépendant du support (MIH) et il n'y a pas génération redondante de clé de sécurité de sorte que les procédures de sécurité peuvent être exécutées avec rapidité.
(KO) 본 발명은 매체 독립 핸드 오버 메시지 전송의 보안 방법 및 그의 장치에 관한 것으로서, 단말기가 액세스 라우터와 인증 절차를 수행하여 마스터 세션 키를 생성하는 마스터 세션 키 생성 단계, 상기 액세스 라우터가 상기 생성된 마스터 세션 키 및 상기 단말기의 어드레스 정보를 정보 서버에 전송하는 키 전송 단계, 상기 정보 서버가 상기 수신한 마스터 세션 키 및 상기 단말의 어드레스 정보를 이용하여 상기 단말기와 메시지 송수신 시 사용될 정보 서버 키를 생성하는 정보 서버 키 생성 단계 및 상기 단말기와 상기 정보 서버가 상기 생성된 정보 서버 키를 이용하여 보안 채널을 형성하는 보안 채널 형성 단계를 포함하는 것을 특징으로 한다. 본 발명에 따르면, 계층 2에서 형성한 키를 계층 3인 MIH 인증 단계에서 사용함으로써 보안 키를 중복하여 생성하지 않으므로 신속한 보안 절차가 수행될 수 있다.
