| titleOfInvention | Countering server-based attacks on encrypted content |
| abstract | Embodiments of the present invention relate to providing encrypted content to authorized content consumers while providing robust traitor tracing. In some embodiments, at least one device key is read. A key block is read. A media key precursor is determined from the key block and the at least one device key. At least one encrypted block key is read. A block master key is determined from the media key precursor. A security program is executed to determine a decrypted block key from the media key precursor, the block master key, and the encrypted block key. The decrypted block key is provided for application to the encrypted content to obtain decrypted content. |
