Abstract

L'invention concerne un procédé et un appareil destinés à permettre la lecture sécurisée et à distance d'un programme multimédia chiffré par une clé de chiffrement de contenu via Internet. Une licence de clé de chiffrement et une clé de déchiffrement de contenu sont transmises séparément et de manière sécurisée au récepteur. La licence de clé de chiffrement est mémorisée dans le module d'accès conditionnel et utilisée ultérieurement pour déchiffrer la clé de chiffrement de contenu de sorte que le programme multimédia puisse être récupéré.
