摘要:Blow-CAST-Fish is a sixteen-round Feistel cipher in which the F function is a part of the private key. In this paper, we show that the disclosure of F allows perform a differential cryptanalysis against a number of rounds. We firstly identify the properties of F function with three active S-boxes to construct the 6-round differential characteristic with the probability 2(-61) and the differential weak keys occur with the probability 2(-12). Then we identify the properties of F function with only one active S-box to construct the 14-round differential characteristic with the probability 2(-49) and the differential weak keys occur with the probability 2(-52). With the above differential characteristics, we can attack 8-round and 16-round Blow-CAST-Fish respectively.
