Abstract
This work aims at determining when the two-round maximum expected differential probability in an SPN with an MDS diffusion layer is achieved by a differential having the fewest possible active Sboxes. This question arises from the fact that minimum-weight differentials include the best differentials for the AES and several variants. However, we exhibit some SPN for which the two-round MEDP is achieved by some differentials involving a number of active Sboxes which exceeds the branch number of the linear layer. On the other hand, we also prove that, for some particular families of Sboxes, the two-round MEDP is always achieved for minimum-weight differentials.
