COMPARING ON EFFECTIVENESS OF SUPERBOXES SOME MODERN SIPHERS
New method of assessment indicators provable security block symmetric ciphers sets out. With application of this method are analyzed for differential properties superblock three ciphers: cipher AES, the reduced version cipher Muhomor and cipher MISTY1. The results of computational experiments to determine the values of AMDP and MADP AES superblock are presented. Demonstrated that the resistance of large ciphers and, in particular cipher Rijndael (AES) is independent of the differential properties of S-blocks used in the ciphers. It seems like one of the promising solutions for building superblocks transformation FI cipher MISTY1, which is noteworthy that sells for one cycle of differential performance random permutation corresponding degree.
of provable security, differential, superblock, random permutation.
