ever hear of ARM ?
Or Trusted Computing Group?
They have been trying as a consortium of the BEST corporations in computer technology to actually harden the hardware at the ROOT level. I have been following this for decade or longer....
It is fascinating in what methodology they have so far come up with. The goal is to keep your stuff safe and multiple factor authentication at bootup is key. ARM architecture is also very involved besides Intel, Mickeysoft, AMD, Broadcom, multiple others.
Just thought this could be something to catch your interest.... McAfee being bought by INtel was one result of this venture....
