Generic Attacks on Unbalanced Feistel Schemes with Contracting Functions

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 kn bits by using d pseudo-random functions from (k–1)n bits to n bits. We describe known plaintext attacks (KPA) and non...
