    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.
