Subject: Announce: Differential Power Analysis

I've posted some preliminary information about Differential Power Analysis
(DPA) at http://www.cryptography.com/dpa. In short, DPA is an attack that
finds keys from information collected from monitoring the power
consumption of smartcards and other crypto hardware. We have implemented
the attack against a large number of actual devices and are not currently
aware of any commercially-available crypto smartcards that are not
susceptable to power analysis attacks.
