(57) Abstract:
(EN): A method and apparatus for performing SIM-based authentication and authorization in a WLAN Internet Service Provider (WISP) network supporting the universal access method (UAM) of authentication and authorization enabling roaming for customers of mobile service providers onto said networks. In addition, the invention provides a secure way of authenticating the customer's client device to the mobile service provider's network by employing temporary credentials for authentication that provide privacy of the user's identity and prevent replay attacks. Finally, if the WISP network supports the 'pass-through' facility, the authentication can be done more securely and quickly.
(FR): La présente invention porte sur un procédé et un appareil qui assurent l'authentification reposant sur la carte SIM et l'autorisation dans un réseau de fournisseur de service Internet WLAN (WISP) fondé sur le procédé d'accès universel d'authentification et d'autorisation permettant à des utilisateurs de fournisseurs de service du réseau mobile d'être itinérants sur lesdits réseaux. La présente invention concerne également un moyen d'authentification sans risque du dispositif client par le réseau du fournisseur de service mobile qui consiste à employer des justificatifs d'identité pour l'authentification qui assurent la confidentialité de l'identité de l'utilisateur et empêchent les attaques par réinsertion. En dernier lieu, si le réseau WISP assure la fonction de transfert, l'authentification peut être effectuée de manière plus sûre et plus rapide.
