Kocher) Organization: Netcom Newsgroups: sci.crypt, sci.crypt.research 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. - -- Paul _____________________________________________________________________ Paul Kocher 870 Market St., Suite 1088 President, Cryptography Research San Francisco, CA 94102 Tel: 415-397-0123 (FAX: -0127) http://www.cryptography.com -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNYtIAee1NzV7EsRFAQGSIgP7BIzzsk508kG5godc8vRyqlc5FUnJbpt5 hAAdYqWSNFBrmk33Wx9T4eH1iTdWbQ2uaSrsWZRsSVm0iOwaT74lwZugag1W+716 T9FxMy+AtcxQp/DCYnGJ+w657jp0nRHduDsOqZfzYJmj/RaPK9WNz9HwXgM+JMrb bIOnyGYSEtk= =oF0k -----END PGP SIGNATURE----- -o- Subscribe: mail majordomoat_private with "subscribe isn".
