Abstract

The known 3-round distinguisher of Rijndael-256 is byte- oriented and 2^8 plaintexts are needed to distinguish 3-round Rijndael from a random permutation. In this paper, we consider the influence of the order of the plaintexts and present a new 3-round distinguisher which only needs 32 plaintexts.
