"Designing and implementing malicious hardware"

A pretty scary paper from the Usenix LEET conference:


The paper describes how, by adding a very small number of gates to a
microprocessor design (small enough that it would be hard to notice
them), you can create a machine that is almost impossible to defend
against an attacker who possesses a bit of secret knowledge. I suggest
reading it -- I won't do it justice with a small summary.

It is about the most frightening thing I've seen in years -- I have no
idea how one might defend against it.

Hat tip: Bruce Schneier's blog.
