my question regarding TPM:
1. what's stopping an attacker from putting a device between the TPM and the rest of the system to fake measurements?
2. how do we know the firmware is measuring itself and not just reporting a hard coded hash?
3. how can we rely on firmware based TPM to measure itself and not lie or just let all the secrets out?
