Adi Shamir's note on a microprocessor bug attack on public key cryptography featured in the NY Times today:


The NYT report:


Can anyone think of a deployed implementation of RSA signatures that would be vulnerable to the attack Shamir mentions? Hashing and message blinding would seem to thwart it.

Incidentally, in the 2001 Boneh-DeMillo-Lipton paper they do mention the Intel floating point division bug.
