Abstract(in English) | In this paper,we propose an evaluation method for DES- like(involution type)cryptosystems based on differential cryptanalysis,and examine the availability of given differential values.We have evaluated three DES-like cryptosystems(DES,FEAL, Multi2). Recently,the modified DES-like cryptosystems have been proposed as an effective counterplot against differential cryptanalysis.The modified DES-like cryptosystems have involution structure which is variable by pre-defined parameters dynamically;we call this ′ dyna mic structure′.We have evaluated dynamic structure by the proposed evaluation method.As a result,we show that the structure is not necessarily strong than expected,as compared with original algorithm. |
