Abstract(in Japanese) (See Japanese page)
Abstract(in English) We study the strength of"data swapping depending on the middle v alue"that was proposed as a method to structure the robust DES- like cryptosystems against differential cryptanalysis.But,the probability of characteristic,based on applied differential cryptanarysis,is 2^-20.9>.This means this is not stronger than the original DES.So,we propose"data rotation depending on the midd le value".The characteristic probability for the cryptosystem applied here is 2^3.83(-n+1)>times(n;round number)as large as that for the original one,so this is stronger than the original.
