But how do we handle hardware attacks? For example, what happens when a

to users systems from the chip level? How can we defend against this?
Unless it's tamper resistant hardware, there is always the electron
microscope to verify the chips itself. It's a big job but could be an
ongoing graduation project at a few universities in
China/Russia/Iran/Iraq. I bet they love to present the evidence of
tampering in an Intel processor.
Other options: in addition to open source, use open hardware designs in
a FPGA. It's slow and expensive (compared to a standard processor) but
good enough for GPG. Use the untrusted processor only for entertainment,
ie decoding movies and playing 3D games.
When the progress in printed (on paper) circuits progresses or self
printed 3d chips comes of age, we don't have to worry about potential
backdoors in Intel processors anymore.
