Huang: Evaluating Precursor’s Hardware Security

Post Syndicated from corbet original

For those who are interested in security at the hardware level, this blog post from
Andrew ‘bunnie’ Huang
is well worth a read. “Despite any claims
you may have heard otherwise, tamper resistance is a largely unsolved
problem. Any secrets committed to a non-volatile format are vulnerable to
recovery by a sufficiently advanced adversary. The availability of
near-atomic level microscopy, along with sophisticated photon and phonon
based probing techniques, means that a lab equipped with a few million
dollars worth of top-notch gear and well-trained technicians has a good
chance of recovering secret key material out of virtually any non-volatile
storage media. The hard part is figuring out where the secrets are located
on the chip.
