Of course it does. You are replaying the logos and screens.

You believe you can boot up an entire VNC client to display something that would take most machines under a second to display?

Which the real machine happily gives me via HDMI/DisplayPort.

Do i need to? That the user presses the power button does not mean the machine will freshly boot. It could also be an unsuspend/wakeup or some regular ACPI event if the machine is only appearing to be off.

This is a completely imaginary scenario. I'd be amazed to see it pulled off.

EDIT: I hear Amazon is still getting pitches for Hacker 2. You might have a shot.

OP is trying to say that this TPM TOTP approach doesn’t help verify a machine is legitimate if there is a possibility that the machine you’re using has been swapped with a malicious one.

This doesn't really mesh well with what the TPM-TOTP idea is trying to solve: trust in the machine you’re using.

Hyperbolic or fairly extreme-sounding scenarios are common when discussing this kind of thing, partly because it makes discussion about a fairly boring topic a little bit more interesting. Don’t get distracted by that.

That being said, using a TPM-based TOTP is pretty extreme sounding in and of itself.
