Abstract

L'invention concerne des méthodes d'authentification effectuées entre un agent de gestion de droits numériques (DRM) d'une carte multimédia et un agent DRM d'un terminal. Cette méthode d'authentification consiste à: demander, par le biais de l'agent DRM du terminal, à un serveur DRM, la validité d'un certificat de l'agent DRM du terminal; demander, par le biais de l'agent DRM du terminal, l'authentification à l'agent DRM de la carte multimédia, lorsque le certificat est valide; authentifier, par le biais de l'agent DRM de la carte multimédia, l'agent DRM du terminal, et transmettre un résultat d'authentification à l'agent DRM du terminal; demander, par l'agent DRM du terminal, au serveur DRM, la validité d'un certificat de l'agent DRM de la carte multimédia; et former un canal de communication pour transmettre des données codées entre l'agent DRM du terminal et l'agent DRM de la carte multimédia, lorsque le certificat est valide.
