Patent

CA 2596872

Key management in a digital cinema system (10, 100 and 1000) occurs by encrypting a feature key associated with encrypted content with a transmission key exchanged with a decryption module (60, 601, 602, 6001, 6002, 6003 and 6004), that serves to decrypt encrypted content. The encrypted feature key undergoes transmission to the decryption module to enable decryption of the encrypted content. In this way, the decryption module will only have the capability of decrypting content based on that module's own key.

L'invention concerne un système de gestion de clés dans un système de cinéma numérique (10, 100 et 1000) par cryptage d'une clé caractéristique associée à un contenu crypté à clé de transmission échangée avec un module de décryptage (60, 601, 602, 6001, 6002, 6003 et 6004) servant à décrypter le contenu crypté. La clé caractéristique cryptée effectue une transmission au module de décryptage afin de décrypter le contenu crypté. De cette façon, le module de décryptage peut uniquement décrypter un contenu en fonction de sa propre clé de module.
