You can't defend against this. There is a lot of research
going into detecting hardware trojans. In general, verifying
that either hardware or software is (or is not) malicious
in undecidable. We are even lacking in tools, short of exhaustive
tests, for verifying that either hardware or software matches
their specs.


The trusted computing group (TCG) standards are meant to address
some of these issues. Unfortunately, it seems that TCG is being
hijacked to enforce walled gardens and keep FOSS out of the
market.
