KFC – The Krazy Feistel Cipher [PDF]
, 2006 We introduce KFC, a block cipher based on a three round Feistel scheme. Each of the three round functions has an SPN-like structure for which we can either compute or bound the advantage of the best d-limited adaptive distinguisher, for any value of d.

FPE scheme based on k-splits Feistel network [PDF]
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 ...

Unbalanced Feistel networks and block cipher design [PDF]
, 1996 We examine a generalization of the concept of Feistel networks, which we call Unbalanced Feistel Networks (UFNs). Like conventional Feistel networks, UFNs consist of a series of rounds in which one part of the block operates on the rest of the block. However, in a UFN the two parts need not be of equal size. Removing this limitation on Feistel networks

Tweaking Key-Alternating Feistel Block Ciphers [PDF]
, 2020 Tweakable block cipher as a cryptographic primitive has found wide applications in disk encryption, authenticated encryption mode and message authentication code, etc. One popular approach of designing tweakable block ciphers is to tweak the generic constructions of classic block ciphers.

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

Multidimensional Linear Cryptanalysis of Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 This paper presents new generic attacks on Feistel ciphers that incorporate the key addition at the input of the non-invertible round function only. This feature leads to a specific vulnerability that can be exploited using multidimensional linear cryptanalysis.

Automated design of a lightweight block cipher with Genetic Programming [PDF]
, 2008 In this paper, we present a general framework for the automated design of cryptographic block ciphers by using Genetic Programming. We evolve highly nonlinear and extremely efficient functions that can be used as core components of any cryptographic ...

A new quantum cryptanalysis method on block cipher Camellia
IET Information Security, 2021 Symmetric cryptography is expected to be quantum safe when long‐term security is needed. Kuwakado and Morii gave a 3‐round quantum distinguisher of the Feistel cipher based on Simon's algorithm.
