Coupled with a robust blinding implementation, you're only really trusting the chip manufacturers (and their tamper proofing of the silicon) at that point. Add an ownership model to the TPM and you've solved anti-theft. Then allow for the addition and removal of authorized components by the owner and you've preserved the right to repair. > and it doesn't have extra hardware inside the case This is the real issue I suppose.
