| titleOfInvention | Adding an additional level of indirection to title key encryption |
| abstract | Systems, methods and media for encrypting and decrypting content files are disclosed. More particularly, hardware and/or software for adding an additional level of indirection to a title key encryption scheme are disclosed. Embodiments may include generating by a cryptographic system a binding key based on binding information. Embodiments may also include encrypting by the cryptographic system a secret key with the binding key and generating a title key associated with at least one content file. Embodiments may also include encrypting by the cryptographic system the title key with the secret key and the at least one content file with the title key. Further embodiments may include receiving an indication that the binding information has changed, generating a new binding key based on the new changed binding information, and re-encrypting the secret key with the new binding key. |
