AMD Ryzen 6000 Series Mobile CPUs Feature Microsoft's Pluton Security

[kiffmet]

I don't see any advantage compared to AMD's current Platform Security Processor, which does also emulate a TPM and supports system RAM encryption… Pluton is sketchy, I trust it even less than AMD's PSP/ARM's Trustzone.

TPM is not really an issue, as long as the rightful owner of the hardware, can freely configure all signatures, the TPM system should accept. So the really interesting question is, does Pluton allow that. If not, you don't have to be a prophet, that AMD will run into major problems within the EU.

WHOLE POINT of TPM2 is that it acts as a small, SIMPLE black box that user can reasonably trust, with small, controlled, SLOW gate into outside world.
There are open-source TPM2 implementations for just that reason.
They contain nothing more than a simple ARM M3 microcontroller.

How can user ever trust your implementation of TPM2 deeply within the CPU ?

Sounds like switching CPUs in future will be a lot more pain and will require a Microsoft account.

You might wanna take a break from wearing the tinfoil hat.

OR you might wanna get yourself an active jamming version:

Michael You need moderators for this forum, you have quite a big collection of idiots in these forums spreading misinformation.

The hardware offers an interface, it should be relatively easy to support it on Linux.
It's also good for security and no, it doesn't require a "Microsoft account" or doesn't go against "open-source" in any way.

Do. Not. Want.

Your circle has a secret language with words ?
Whowouldhavethunkthat ?

What's your shared secret that binds you together ?
That you are morons in some highly specific way ?

Nothing secret about it. Wappie is just how you say crackpot in Dutch.

FWIW, there are some Pluton drivers in the Azure Sphere OS kernel (basically a Microsoft's Linux distro for IoT devices): https://github.com/crpietschmann/Azu...earch?q=pluton
