  • Abstract
    Recently it was shown (by J. Patarin) how to distinguish a general five-round Feistel network from a random permutation using 𝒪(23n2/) chosen plaintexts or 𝒪(27n4/) known plaintexts. The present authors report improvement of these results and a distinguisher is presented which uses roughly 2n chosen plaintexts or roughly 23n2/ known plaintexts.
