英文摘要: |
The strict avalanche criterion (SAC) is one of the most important cryptographic criteria for substitution boxes (S-boxes) used in many symmetric encryption systems. However, there are few constructive methods for S-boxes fulfilling the SAC until now. In this paper, to construct S-boxes satisfying the SAC directly, we generalize the concatenation techniques of Boolean functions to S-boxes. Using the idea of concatenating small variable S-boxes, we present a simple yet effective construction method of S-boxes satisfying the SAC. Finally, a simple example on how to construct SAC S-boxes with large input variables by small variables SAC S-boxes is given. |
