Title (EN) METHOD AND APPARATUS FOR PROVIDING A SECURE MOVE OF A DECRYPTION CONTENT KEY
(FR) PROCEDE ET APPAREIL PERMETTANT LE DEPLACEMENT SECURISE D'UNE CLE DE DECHIFFREMENT DE CONTENU
Abstract:
(EN) The present invention discloses an apparatus and method for providing a secure move of a content decryption key within or between domains. Namely, the present invention addresses the single copy usage rule by restricting the movement of the decryption key instead of restricting the movement of the encrypted content itself.
(FR) La présente invention se rapporte à un appareil et à un procédé permettant le déplacement sécurisé d'une clé de déchiffrement de contenu à l'intérieur de domaines ou entre ces derniers. Précisément, la présente invention consiste à appliquer la règle de l'usage de copies uniques, en limitant le déplacement de la clé de déchiffrement au lieu de limiter le déplacement du contenu chiffré lui-même.
