Generic Attacks on Alternating Unbalanced Feistel Schemes
Valerie Nachef
Abstract
\begin{abstract}
Generic attacks against classical (balanced) Feistel schemes, unbalanced Feistel schemes with contracting functions and unbalanced Feistel schemes with expanding functions have been studied in \cite {P01}, \cite{Jut}, \cite{PNB06}, \cite{PNB07}. In this paper we study schemes where we use alternatively contracting random functions and expanding random functions. We name these schemes ``Alternating Unbalanced Feistel Schemes''. They allow constructing pseudo-random permutations from
