A pretty scary paper from the Usenix LEET conference: http://www.usenix.org/event/leet08/tech/full_papers/king/king_html/
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.
