Hi all, I'm currently doing some experiments with dynamic root of trust. From the tboot boot log I can see that the SENTER instruction is executed and the PCRs 17 and above are set to 0 and that PCRs 17 and 18 are extended. My question, if somebody could help me, is how to set PCR 17 or any other PCR to 0 from the running system and if I understand correctly the PCR value should change if I boot another XEN domain and should change back to the original value if I shut it down? Or am I mistaken? I'd appriciate any help. Best, Atanas |
