Trusted Platform Module

Post by dhartman » Tue May 15, 2018 6:50 pm

I am in the process of a new build an as I'm putting it all together I was wondering if anyone in Linux or any other OS ever uses the trusted platform module! I don't recall anybody talking about it an was wondering if it's even a thing or not! Just curious I Guess :) Thanks for You time

Sorry, I guess I didn't explain myself to well :oops: I know what it is and how to use TPM I was wondering (poll type) if people actually use this hardware,software on his or her system's? As I can't recall it ever being a discussion on this in the forum before!

The only time i've ever seen it discussed was when Windows 8 came out and most people on the linux forums suggested it was turned off in the Bios. :)

Google TPM backdoor and you'll see why it was suggested.

*edit*

Example:

Germany warns: You just CAN'T TRUST some Windows 8 PCs
Microsoft: You can still buy an 'insecure' Win 8 machine sans TPM chip

AMD Ryzen comes equipped with a TPM. Amongst other things, it's useful for making sure that the Linux kernel doesn't run out of random entropy.

AMD promises firmware fixes for security processor bugs

https://arstechnica.com/gadgets/2018/03 ... ssor-bugs/
In theory, the PSP is able to keep secrets even from the x86 CPU; this ability is used for the firmware TPM capability, for example. However, the Ryzenfall and Fallout bugs enable an attacker to run untrusted, attacker-controlled code on the PSP. This attacker code can disclose the PSP's secrets, undermining the integrity of the firmware TPM, AMD's encrypted virtual memory, and various other platform features.

The Masterkey bug is worse; the PSP does not properly verify the integrity of its firmware. A system that enabled a malicious firmware to be flashed could have a malicious PSP firmware permanently installed, persisting across reboots.
Maybe when they fix it.

Nice to see AMD prove the experts wrong with a fast patch turn around as it was reckoned that Chimera would take months and be as bad as Intels problems , so one up for them over Intel.
