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.
