20130044874 | CRYPTOGRAPHIC CIRCUIT AND METHOD THEREFOR - Data security is facilitated. In accordance with one or more embodiments, a target circuit is used to generate encryption information specific to the target circuit. The encryption information is used for generating data corresponding to a key, such as for decrypting media content. In some implementations, encryption information is used together with key data to generate a key offset. The key offset is subsequently used, together with newly-generated encryption information, to obtain the key. | 02-21-2013 |
