I've a question regarding the authentication of the ac module.
I understand that the header of the ac module features the rsa public
key to verify the signature provided in the module header.
My question is: How is the rsa pulic key verified?
The Trusted Execution Technology - Developer's Guide mentions that the
hash of the public key is computed and compared. Compared to what?
Is this hash stored somewhere in the chipset or the cpu? Is it possible
to update this hash in case the key pair gets compromised?
