I'm curious if that means that it's now illegal for the company to tell you if you have a device with fake parts.
I also don't quite understand the security implications. If you need some attested part, like a TPM, and this and some other thing like a fingerprint sensor fail and you replace them both, you cannot disable the fingerprint sensor since now technically it cannot attest itself?
- grishka 1y agoWhy not allow pairing the fingerprint sensor with the SoC fully offline?
- miki123211 1y agoPresumably, you can have the TPM tie fingerprint data to the sensor. If you replace the sensor with a "fake" one, old fingerprint data becomes invalid. This would be good enough for users, as adding their fingerprints back would take them minutes at most, while providing no value for attackers.
