Serge Vaudenay

Serge Vaudenay (5 April 1968-) is a well-known French cryptographer.

Serge Vaudenay entered the École Normale Supérieure in Paris as a "normalien" student in 1989. In 1992, he passed the "agrégation" in mathematics. He did his PhD at the computer science laboratory of École Normale Supérieure, and defended it in 1995 at the University of Paris 7; his advisor was Jacques Stern. From 1995 to 1999, he was a senior research fellow at CNRS. In 1999, he moved to a professorship at the École Polytechnique Fédérale de Lausanne where he is at the lead of the Laboratory of Security and Cryptography (LASEC).LASEC is host to two popular security software developed by its members.iChair is developed by Thomas Baignères and Matthieu Finiasz, and is a popular online submission and review server used by many cryptology conferences.
Ophcrack is a Windows password cracker based on rainbow tables by Philippe Oeschlin. Vaudenay has published several papers related to cryptanalysis and design of block ciphers and protocols. He is one of the authors of the IDEA NXT (FOX) algorithm (together with Pascal Junod). Vaudenay also discovered a severe vulnerability in the SSL/TLS protocol. The attack he forged could lead to the interception of the password. He also published a paper about biased statistical properties in the Blowfish cipher and is the author of the best attack on the Bluetooth cipher : E0. In 1997 he introduced decorrelation theory, a system for designing block ciphers to be provably secure against many cryptanalytic attacks.

Vaudenay was appointed program chair of Eurocrypt 2006, PKC 2005, FSE 1998; and in 2006 elected as board member of the International Association for Cryptologic Research.
