The conspiracy theories are funny, but the bullshit situation of being locked out of things you yourself OWN isn't. I think that's what most of us hate about things like ME or PSP.
- my123 5y agoBeing a TPM is one of the Intel ME and PSP’s functionalities. Making a TPM that’d be secure against custom firmware is possible, but isn’t very implemented across the industry. It’d need measuring the hash of the loaded firmware itself to hardware managed PCRs that affect the hardware crypto engines. Something that’s done on the Secure Enclave for Apple A13 onwards AFAIK. (also… managing DRM systems, they’ll have to be put on a coprocessor somewhere.)
- floatboth 5y agoME/PSP isn't that offensive in terms of "locking you out", it's just a coprocessor that's there. Intel Boot Guard on the other hand can actually prevent custom firmware from running.
