Since 2010, I am a Cryptography & Security Expert for CryptoExperts in Paris !
I received a Ph.D. in 2008 under the direction of Prof. Serge Vaudenay, head of the Cryptography and Security Laboratory (LASEC) at EPFL, Switzerland. My main research areas cover block ciphers and their cryptanalysis. I then spent some time in Belgium where I worked as a consultant and researcher for Smals.
I am part of the program committee of the 2011 edition of the ECRYPT Workshop on Lightweight Cryptography.
LC 2011 is organized by the UCL Crypto Group and sponsored by the SymLab and VAMPIRE virtual labs of the Network of Excellence in Cryptology - ECRYPT II. It will be held on November 28-29, 2011, in Louvain-la-Neuve in Belgium.

@veorq double-check your information. iChair only stores passwords in .htpasswd files using salted MD5 (about 1000 rounds of it).16/05/13 at 10:08 by Thomas Baignères

We introduce KFC, a block cipher based on a three round Feistel scheme. Each of the three round functions has an SPN-like structure for which we can either compute or bound the advantage of the best \(d\)-limited adaptive distinguisher, for any value of \(d\). Using results from the decorrelation theory, we extend these results to the whole KFC construction. To the best of our knowledge, KFC is the first practical (in the sense that it can be implemented) block cipher to propose tight security proofs of resistance against large classes of attacks, including most classical cryptanalysis (such as linear and differential cryptanalysis, taking hull effect in consideration in both cases, higher order differential cryptanalysis, the boomerang attack, differential-linear cryptanalysis, and others).
