This post seems on point but I didn’t understand the answer enough to answer this question.
Intel’s vPro offers “Total Memory Encryption” (TME), which encrypts RAM and system bus data while the computer is on. Does TME encryption improve the security of a computer when its screen is locked? That is, if the computer has implemented Full Disc Encryption (e.g., Debian with Luks/dmcrypt), will a TME enabled computer (that is on with a locked screen) be harder to attack because the RAM is encrypted behind the locked screen? Does the RAM encryption improve the security of the FDE key being held in RAM?
