Extended Generalized Feistel Networks using Matrix Representation
Thierry Pierre Berger, Marine Minier, Thierry Pierre Berger, Marine Minier · 2013
Abstract. While Generalized Feistel Networks have been widely studied in the literature as a building block of a block cipher, we propose in this paper a unified vision to easily represent them through a matrix repre-sentation. We then propose a new class of such schemes called Extended Generalized Feistel Networks well suited for cryptographic applications. We instantiate those proposals into two particular constructions and we finally analyze their security.
