Abstract

In this paper, we examine the security of block ciphers referred to as substitution-permutation networks (SPNs). When the SPN has 2-round, we obtain an upper bound on the maximum differential probability. We also obtain an upper bound on the maximum linear hull probability. Our results extend and sharpen the known results for the 2-round SPNs.
