Problem of a TPM is that it’s not an integrated chip, you can easily intercept messages going to and coming from the TPM

- floatboth 6y agoDiscrete TPMs have been going out of fashion, fTPM (firmware tpm, i.e. soft TPM located in ME/PSP) has been standard for a few years now.
- baby 6y agoYeah I've read the fTPM paper that made use of SGX, but it sounded like it had some limitation (needed fuses to prevent rollbacks, etc.) From the article it also looks like Pluton will implement the TPM API, but I guess that's just to remain compatible.
