Extended Generalized Feistel Networks using Matrix Representation [PDF]
, 2013 International audienceWhile 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 representation. We then propose

Yoyo trick on type‐II generalised Feistel networks [PDF]
IET Information Security, 2021 This work presents a structural attack against the type‐II generalised Feistel network (GFN) with secret internal functions. First, equivalent structures of the 7‐round type‐II GFN are provided, which helps reduce the first guess of the secret round ...

Information leakage of 1-Nested-Feistel network
Journal of Physics: Conference Series, 2018 Impossible differential cryptanalysis is a powerful tool to evaluate the strength of a block cipher structure. In this paper, we investigate the impossible differential property of Nested-Feistel networks, which is a famous block cipher network used in ...

FPE scheme based on k-splits Feistel network
Tongxin xuebao, 2012 The construction features and discipline of Feistel network-based FPE(format-preserving encryption)schemes were analyzed.Considering on the problem that 2-splits Feistel networks-based FPE cipher’s block size was in narrow range,a type-2 Feistel network ...

Multiset Structural Attack on Generalized Feistel Networks [PDF]
Mathematical Problems in Engineering, 2019 In this paper, we present new generic multiset attacks against generalized Feistel networks, by which we can recover all the unknown round functions completely instead of deciding whether an unknown encryption oracle is such network or a random permutation.

On groups generated by ciphers based on Feistel network
Matematicheskie Voprosy Kriptografii [Mathematical Aspects of Cryptography], 2021 Исследуются шифры, построенные по схеме Фейстеля, у которых функции усложнения представляют собой одну или несколько итераций XSL-схемы. Приводятся достаточные условия, при которых итерационные преобразования таких шифров порождают знакопеременную группу.
