Abstract

L'invention concerne des adresses MAC temporaires uniques (Fig. 2, 203) qui sont calculées par des appareils mobiles connectés à des réseaux sans fil, en utilisant un point d'accès annonçant des informations (201) en combinaison avec l'adresse MAC permanente de l'appareil mobile (202). Les appareils mobiles utilisent une fonction de hachage pour construire une séquence de bit à partir de laquelle une adresse MAC temporaire peut être extraite. L'adresse MAC est unique sur toute la région dans laquelle l'appareil mobile peut fonctionner, sans qu'il soit nécessaire d'effectuer une coordination ou négociation entre les différents points d'accès de la région.
