We improve the best attack on Rijndael reduced to 6 rounds from complexity 272 to 244 . We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round R...

Rijndael is a block cipher designed by V. Rijmen and J. Daemen and it was chosen in its 128-bit block version as AES by the NIST in October 2000. Three key lengths - 128, 192 or 25...
Rijndael is the new Advanced Encryption Standard designed by V. Rijmen and J. Daemen and chosen as AES by the NIST in October 2000. Surprisingly, the number of cryptanalyses agains...
Due to recent breakthroughs in hash functions cryptanalysis, some new hash schemes have been proposed. GRINDAHL is a novel hash function, designed by Knudsen, Rechberger and Thomse...
Since Rijndael was chosen as the Advanced Encryption Standard, improving upon 7-round attacks on the 128-bit key variant or upon 8-round attacks on the 192/256-bit key variants has...
