Abstract
An authenticated code module comprises a value that attests to the authenticity of the module. The value is encrypted with a key corresponding to a key of a computing device that is to execute the module.
Claims20
A code module comprising
- code to be executed by a computing device;
- and
- a signature that attests to the authenticity of the code, the signature encrypted such that the computing device is capable of decrypting the signature using a key embedded in a chipset of the computing device.
A machine readable medium comprising
- code pages comprising code to be executed by a computing device;
- and
- a value that fingerprints the code pages, the value encrypted such that the computing device is capable of decrypting the value using a key embedded in a processor of the computing device.
A machine readable medium comprising
- data pages comprising data;
- code pages comprising code to be executed by a computing device;
- and
- a value that fingerprints the data pages and the code pages, the value encrypted such that the computing device is capable of decrypting the value using an asymmetric key embedded in a hardware component of the computing device.
