DEAL is a six- or eight-round Luby-Rackoff cipher that uses DES as its round function, with allowed key lengths of 128, 192, and 256 bits. In this paper, we discuss two new result...
This paper considers iterated ciphers and their resistance against linear and differential cryptanalysis. In the theory of these attacks one assumes independence of the round keys...
Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...
In this paper we analyze the block cipher SAFER K. First, we show a weakness in the key schedule, that has the effect that for almost every key there exists on the average three an...
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...
