Patent ID: 8266429

Claim:
A device for receiving encrypted content from a storage unit, the device and the storage unit both being associated with a user, the encrypted content being decrypted in the device using a first cryptographic element, the device comprising: a first interface for receiving a first encrypted version of the first cryptographic element from the storage unit, the first encrypted version of the first cryptographic element being generated by encrypting the first cryptographic element using a second cryptographic element which is associated with the user, the first encrypted version of the first cryptographic element being provided to an apparatus remote from the device, the apparatus recovering the first cryptographic element based on at least the first encrypted version of the first cryptographic element and data representative of the user; a second interface for receiving from the apparatus a second encrypted version of the first cryptographic element, the second encrypted version of the first cryptographic element being generated by encrypting the recovered first cryptographic element using a third cryptographic element which is associated with the device; and a module for recovering the first cryptographic element to decrypt the encrypted content based on at least the second encrypted version of the first cryptographic element.
