Abstract. Misty schemes are classic cryptographic schemes used to construct pseudo-random permutations from 2n bits to 2n bits by using d pseudo-random permutations from n bits to ...

In this paper, we describe generic attacks on unbalanced Feistel schemes with contracting functions. These schemes are used to construct pseudo-random permutations from kn bits to ...

Let A be a Feistel scheme with 5 rounds from 2n bits to 2n bits. In the present paper we show that for most such schemes A:
