Abstract
Rijndael-like structure is a special case of SPN structure.The linear transformation of Rijndael-like structures consists of lineartransformations of two types, the one is byte permutation π and theother is linear transformation θ = (θ1, θ2, θ3, θ4), where each of θi separatelyoperates on each of the four columns of a state. Furthermore,π and θ have some interestingprop erties. In this paper, we present anew method for upper boundingthe maximum differential probabilityand the maximum linear hull probability for Rijndael-like structures. Byapplyingour method to Rijndael, we obtain that the maximum differentialprobability and the maximum linear hull probability for 4 rounds ofRijndael are bounded by 1.06 × 2−96.
