A computer with no input mechanism or output mechanism would be secure. Just not very useful.
I imagine any computer that approaches maximum security also approaches minimum utility.
Presumably the author just thinks that Intel is a little too low on security compared to the other offerings, and not that the other offerings are actually "secure".
- saagarjha 8y ago> A computer with no input mechanism or output mechanism would be secure. Information can be extracted from airgapped computers by measuring magnetic fluctuations, so this isn't quite true!
- wilsonnb 8y agoI suppose that would count as an output mechanism then, wouldn't it? Perhaps it is impossible to build a computer without an output mechanism.
- luminiferous 8y agoIf you're going to count all possible side channels as output mechanisms, then I'd imagine that it is indeed impossible to build a computer without an output mechanism. Unless you limit your scope to say, Earth, and somehow build a computer outside of Earth's light cone. It is thus causally disconnected from Earth and has no output mechanisms that can be read from anyone on Earth.
