10-12 May 2004, Hilton Hotel Bonn, Germany

Between August 1998 and April 2000 NIST organized 3 conferences on the Advanced
Encryption Standard. In October 2000, the selection of Rijndael as proposed AES
was announced. In November 2001, the AES was announced officially in FIPS 197.

The evaluation of the cryptographic strength of Rijndael hasn't stopped after the
announcement and official publication of the AES. On the contrary, the increased
visibility of the algorithm selected has spurred many interesting new approaches to cryptanalyze (reduced versions of) Rijndael.

The Ruhr-University of Bochum organizes the fourth conference on the AES, in
cooperation with the Graz University of Technology and NIST.

The goal of the conference is to provide an overview of the newest developments related to the cryptographic security of the AES and to bring interested cryptographers together.
