Abstract(in English) | In this paper, we propose a new security evaluation against differential/linear cryptanalysis, and discuss its effectiveness. This evaluation is very useful for designing secure encryption algorithms. It can provide more practical criterion than the maximum average of differential/linear probability, and more secure criterion than the differential/linear characteristic probability. According to the evaluation, it comes out the possibility of another structure of encryption algorithms even if it is an easy implementation for high-speed to diminish the number of S-boxes. And, we present examples of round function which is designed under above design policy. |
