Title (EN) SMART CARD AUTHENTICATED DOWNLOAD
(FR) TÉLÉCHARGEMENT AUTHENTIFIÉ PAR CARTE À PUCE
Abstract:
(EN) Described herein are systems and methods for providing a targeted and secure software image or other data to a television receiver. The data item can be provided to the smart card through a television service provider distribution system in blocks of data that are small enough to be processed by the smart card. For each block of data, the smart card can decrypt the block of data with a global network key, generate a partial hash representing the block of data, update a full hash with the partial hash, encrypt the block of data with a dynamically generated item key, and transmit the encrypted block of data to the television receiver. Once complete, the smart card can security check the software image including an integrity check using the full hash. If the security check passes, the smart card can transmit the dynamically generated item key to the television receiver.
(FR) L'invention concerne des systèmes et des procédés permettant de fournir une image logicielle ciblée et sécurisée ou d'autres données à un récepteur de télévision. L'élément de données peut être fourni à la carte à puce par l'intermédiaire d'un système de distribution de fournisseur de services de télévision dans des blocs de données suffisamment petits pour être traités par la carte à puce. Pour chaque bloc de données, la carte à puce peut déchiffrer le bloc de données avec une clé de réseau globale, générer un hachage partiel représentant le bloc de données, mettre à jour un hachage complet avec le hachage partiel, chiffrer le bloc de données avec une clé d'élément générée de manière dynamique, et transmettre le bloc chiffré de données au récepteur de télévision. Une fois achevée, la carte à puce peut vérifier la sécurité de l'image logicielle comprenant un contrôle d'intégrité à l'aide du hachage complet. Si le contrôle de sécurité réussit, la carte à puce peut transmettre la clé d'article générée dynamiquement au récepteur de télévision.
