Welcome to the web site of Thomas Baignères

These are the slides of a presentation I made on the 5th of February 2009 at the [Université Catholique de Louvain], where I was invited by [Prof. Gildas Avoine] from the [Information Security Group].

(Very Short) Abstract: Block ciphers probably figure in the list of the most important cryptographic primitives. Although they are used for many different purposes, their essential goal is to ensure confidentiality. This thesis is concerned by their quantitative security, that is, by measurable attributes that reflect their ability to guarantee this confidentiality.

I am one of two General Chairs of [FSE 2008] that will be held in Lausanne in February, 2008. FSE 2008 is the 15th annual Fast Software Encryption workshop. It is sponsored by the International Association for Cryptologic Research ([IACR]). Original research papers on symmetric cryptology are invited for submission to [FSE 2008]. The workshop concentrates on fast and secure primitives for symmetric cryptography, including the design and analysis of block ciphers, stream ciphers, encryption schemes, analysis and evaluation tools, hash functions, and message authentication codes (MACs).

Of course, we use [iChair] to manage the submission and the review processes.

iChair is a powerful submission/review server software designed to help the program chair of a conference with submission collection, assignments of articles to reviewers, review collection, discussions, mailing, ...

iChair was developed with a view to being as easy to install as possible. As a result, installation on a Linux box should be possible by anyone (even with only basic knowledge of server administration) in about one or two hours. It might even be possible to run it on a windows based server (but this was never tested). It was developed in PHP5 and intended to run on an apache web server.

iChair has already been used for several conferences, including CrapOCrypt 2006 (a fake test conference), Eurocrypt 2006, ANTS VII, ACISP 2006, Crypto 2006, SAC 2006, ICISC 2006, Vietcrypt 2006, CANS 06, Asiacrypt 2006, Inscript 2006, Pairing 2007, Indocrypt 2006, PKC 2007, ISPEC 2007, ACISP07, FSE 2007, WISTP 2007, WCC 2007, CARDIS 2008, Inscrypt 2007, WAIFI 2007, ICITS, Kryptographie - Theorie und Praxis, Provable Security 2007, IWSEC 2007, Special Issue on Cryptography in Computer System Security, WISSec 2007, International Conference on Information Theoretic Security, Cryptography and Coding, CANS 2007, AfricaCrypt 2008, FSE 2008,  ...

If you want to use iChair for one of your conferences, you should contact me or Matthieu Finiasz.

Undergraduate semester project on Daniel Bleichenbacher's attack against the RSA encryption standard. This project was realized under the supervision of Pascal Junod in 2002.
