Abstract

Système d'authentification de stations mobiles et de stations de base dans un réseau de télécommunications cellulaires. Le système comprend un algorithme qui, à la suite d'une interrogation aléatoire, génère non seulement une réponse dépendant d'une clé, mais aussi une clé temporaire pour la conversation ou une variable d'appel, qui peut servir à chiffrer le trafic du réseau. Pour se protéger contre des clones dans le réseau, l'algorithme se sert d'une clé à codage roulant qui contient de l'information antérieure. Une procédure d'authentification bilatérale peut être utilisée pour mettre à jour la clé et pour générer une nouvelle clé pour la conversation.
