Generic Attacks on Unbalanced Feistel Schemes with Expanding Functions
Unbalanced Feistel schemes with expanding functions are used to construct pseudo-random permutations from kn bits to kn bits by using random functions from n bits to (k − 1)n bit...

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 ...

On Generalized Feistel Networks
We prove beyond-birthday-bound security for most of the well-known types of generalized Feistel networks: (1) unbalanced Feistel networks, where the n-bit to m-bit round functions ...

Domain Extension of Public Random Functions: Beyond the Birthday Barrier
A public random function is a random function that is accessible by all parties, including the adversary. For example, a (public) random oracle is a public random function {0, 1}â...
