Efficient Padding Oracle Attacks On Cryptographic Hardware

Posted Jun 27, 2012

Authored by Riccardo Focardi, Graham Steel, Joe-Kai Tsay, Lorenzo Simionato, Yusuke Kawamoto, Romain Bardou

This paper demonstrates how to exploit the encrypted key import functions of a variety of different cryptographic devices to reveal the imported key. The attacks are padding oracle attacks, where error messages resulting from incorrectly padded plaintexts are used as a side channel. This is the paper that made headlines regarding RSA tokens being cracked in 13 minutes.
