Paul Kocher's brutally clever timing attack against on-line
implementations of RSA, DSA and fixed-exponent Diffie-Hellman
is reported on page A1 of Monday's New York Times ("Secure Digital
Transactions Just Got a Little Less Secure" by John Markoff).
The attack requires only a few thousand ciphertext samples and works
against most implementations of public-key cryptosystems in which
the attacker can measure accurately the target's computation time for
each sample.
I think Kocher's paper is online somewhere; I'll post the URL
when I find it.
