| This book constÐtutes the thoroughly refereed postproceedings of the 4th International Conference on the Advanced Encryption Standard, AES 2004, held in Bonn, Germany in May 2004. The 10 revised full papers presented together with an introductory survey and 4 invited papers by leading researchers were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on cryptanalytic attacks and related topics, algebraic attacks and related results, hardware implementations, and other topics. All in all, the papers constitute a most up-to-date assessment of the state of the art of data encryption using the Advanced Encryption Standard AES, the de facto world standard for data encryption.
This volume comprises the proceedings of the 4th Conference on Advanced Encryption Standard, ‘AES — State of the Crypto Analysis,’ which was held in Bonn, Germany, during 10–12 May 2004.
The conference followed a series of events organized by the US National Institute of Standards and Technology (NIST) in order to hold an international competition to decide on an algorithm to serve as the Advanced Encryption Standard (AES). In 1998, at the first AES conference (AES 1), 15 different algorithms were presented, discussed, reviewed and verified. A second conference was organized in April 1999, and by August 1999 only five candidates were still in the running: MARS, RC6, Rijndael, Serpent and Twofish. After a further conference devoted to verification, testing and examination of the candidate algorithms in order to prove their performance and security, one winning algorithm remained. The encryption scheme Rijndael, designed by the Belgian cryptographers Joan Daemen and Vincent Rijmen, was selected in 2000 to become the successor to the famous DES (Data Encryption Standard) and it is now the Advanced Encryption Standard. |
