"WebbAs application, we find the best probability of the differential characteristics for 4∼15 rounds SM4 in the single-key model. The results show that the best probability of differential characteristics of the 15-round SM4 is 2−82with 12 active S-boxes. The exact lower bound of the number of differentially active S-boxes of the 16-round SM4 is 15. " - Sm4 sboxtable
