This is AMD’s method for dealing with firmware persistent malware, root kits, and boot kits. It works in tandem with the AMD Secure Processor (ASP) which is a bit of silicon in their pro series chips that handles security and management. Similar to Intels Management Engine. It actually works pretty well in defending against Return-on-Programming attacks.Can somebody describe the break in the trusted boot chain that they are trying to fix with the CPU fixed to the board?
What is the security problem they claim to fix?
Since it works to encrypt all data moving across the system it also does well in defending or mitigating Spectre, Meltdown, and all those other side channel attacks that were going around.
