CA 2635744

Methods and apparatus for protecting user privacy in a shared key system (100). According to one aspect, a user (114) generates a derived identity (108) based on a key (102) and a session variable, and sends the derived identity to an application (116). In one embondiment, a key server (126) may be used to receive the derived identity from the application, and return a sub- key (138) to the application to use for encrypting communications with the user.

L'invention concerne des procédés et un appareil de protection de la vie privée d'un utilisateur dans un système de clé partagée. Selon un aspect, un utilisateur fournit une identité dérivée reposant sur une clé et une variable de session et envoie cette identité dérivée à une application. Dans un mode de réalisation, un serveur de clés est utilisé pour recevoir l'identité dérivée provenant de l'application et retourner une sous-clé à l'application en vue de l'utiliser pour chiffrer des communications avec l'utilisateur.
