Title (EN) METHOD AND SYSTEM FOR INTER-SUBNET PRE-AUTHENTICATION
(FR) PROCEDE ET SYSTEME DE PRE-AUTHENTIFICATION ENTRE SOUS-RESEAUX
Abstract: front page image
(EN)A method and system for performing pre-authentication across inter-subnets. A pre-authentication request is received by a first access point associated with a first subnet from a mobile node requesting that is requesting pre-authentication with a second access point associated with a second subnet. The request is forwarded by the access point to a first authenticator that is the authenticator for the first subnet. The first authenticator obtains from a root infrastructure node the address for a second authenticator that is the authenticator for the second access point. The first authenticator then pre-authenticates the mobile node with the second authenticator by sending a message to the address for the second authenticator.
(FR)L'invention concerne un procédé et un système de pré-authentification dans des sous-réseaux. Une demande de pré-authentification est reçue par un premier point d'accès associé à un premier sous-réseau d'un noeud mobile demandant une pré-authentification auprès d'un second point d'accès associé à un second sous-réseau. La demande est transmise par le point d'accès à un premier dispositif d'authentification du premier sous-réseau. Le premier dispositif d'authentification obtient d'un noeud d'infrastructure racine l'adresse d'un second dispositif d'authentification du second point d'accès. Le premier dispositif d'authentification procède alors à la pré-authentification du noeud mobile auprès du second dispositif d'authentification par envoi d'un message à l'adresse du second dispositif d'authentification.
