In this paper, we report on our design of a choosen plaintext attack with work factor 2252 to recover of the first and the last subkeys of a 7-round Rijndael, while differential cryptanalysis against Rijndael have been done for up to 6 rounds...

In this paper, we propose a genetic algorithm, called GenSPN,

for finding highly probable differential characteristics of substitutionpermutation

networks (SPNs). A special fitness function and a heuristic< ...

We have developed a model to represent the differential operation of block ciphers in order to help finding differential

characteristics. Through this model, the whole space of differential characteristics for a ...
