Improved Generic Attacks on Unbalanced Feistel Schemes with Expanding Functions

Abstract

“Generic” Unbalanced Feistel Schemes with Expanding Functions are Unbalanced Feistel Schemes with truly random internal round functions from n bits to (k−1)n bits with k ≥ 3. From a practical point of view, an interesting property of these schemes is that since n < (k− 1)n and n can be small (8 bits for example), it is often possible to store these truly… (More)
