Integrating message authenticity #127
Description
What kind of replay attacks are being talked about here? This is CPUID functionality and the data is available via an M-mode pointer, and thus is hidden away from even HS/S-mode firmware.
This reads like fairly vague arm waving around something that is not an actual usable feature. The section even mentions that signing is optional. I'd drop it entirely.
