@hon1nbo @foone yeah, but all these things would essentially necessitate a fundamentally incompatible #Fork of the #USB standard, creating #costs, #fragmentation and lessen the likelyhood of success.

I gues a sort-of "Secure HID Port" that mandates proper authentification and does full #E2EE from the Keyboard Matrix / Pointing Device controller up is an option, but you'd have to expect state-sponsored attackers willing to do "Kamikaze" Hacks...
- There's like a long talk by #TonyChen from #Microsoft explaining how they secured the #XboxOne.
#TLDW: It requires custom silicon and a hard root of trust…
- And as we saw with #GoldenKeyBoot all it takes is a single #leak of a #PrivateKey and that entire system is fucked!
