yes sniffing is possible, for now im waiting for some pluton variant to start making its way into the chip and die stream.
the concept is to shield the TPM its bus, and any keys whith the CPU chip.
- wolvoleo 5mo agoCurrent TPMs already have the ability to encrypted the comms to the CPU. Motherboard manufacturers just don't bother implementing it.
- rolph 5mo agoPluton is about physically placing the TPM behind the CPU die, its more than a SoC it eliminates the possibility of getting to the TPM at all, you wont be able to drill into the chip to access bus lines without mangleing the whole thing. no sniffing would be possible after Pluton chips, even if you could decrypt. but as i said, for now you can still sniff.
- wolvoleo 5mo agoOh yes but you shouldn't have to be able to do that. If the TPM2 spec were properly implemented. Physical hardening and protocol hardening are complementary features, not alternatives. It's better to have both in case one of them has a flaw. Ps I'm not very sold on having this stuff in the CPU, there's so much industry focus on giving up control to big tech. I don't want to get to the situation we already have on mobile where having root on my own system is considered a bad thing. I trust myself one hell of a lot more than Google or Microsoft.
