Abstract
Une méthode sûre de distribution de contenu ou daccès à un contenu peut comprendre la coordination au sein de trois dispositifs tels que des serveurs, soit un serveur de gestion de contenu, un serveur de distribution et un serveur dautorisation. Une demande de contenu peut provenir dune application de serveur dautorisation et nécessiter lobtention par lapplication de deux jetons signés numériquement pour la demande. Le premier jeton peut provenir du serveur dautorisation et comprendre un identifiant de serveur de gestion de contenu pour le contenu demandé. Le second jeton peut comprendre deux identifiants pour le contenu : le premier étant lidentifiant du serveur de gestion de contenu et le second étant un identifiant de serveur de distribution. Les premier et second jetons peuvent être signés respectivement par le serveur dautorisation et le serveur de gestion de contenu, et être fournis au serveur de distribution à des fins de validation. Une validation réussie peut faire en sorte que le serveur de distribution fournisse une clé de déchiffrement de contenu pour le contenu demandé au dispositif demandant le contenu.
