摘要:
An augmented boot code module includes instructions to be executed by a processing unit during a boot process. The augmented boot code module also includes an encrypted version of a cryptographic key that can be decrypted with a cryptographic key that remains in the processing unit despite a reset of the processing unit. In one embodiment, the processing unit may decrypt the encrypted version of the cryptographic key and then use the decrypted key to establish a protected communication channel with a security processor, such as a trusted platform module (TPM). Other embodiments are described and claimed.
