A Fast Color Image Encryption Algorithm Using 4-Pixel Feistel Structure. [PDF]

open access: yesPLoS ONE, 2016
Algorithms using 4-pixel Feistel structure and chaotic systems have been shown to resolve security problems caused by large data capacity and high correlation among pixels for color image encryption. In this paper, a fast color image encryption algorithm

Throwing Boomerangs into Feistel Structures

open access: yesIACR Transactions on Symmetric Cryptology, 2022
Automatic tools to search for boomerang distinguishers have seen significant advances over the past few years. However, most previous work has focused on ciphers based on a Substitution Permutation Network (SPN), while analyzing the Feistel structure is

Cryptanalysis of a Generalized Unbalanced Feistel Network Structure [PDF]

open access: yesLecture Notes in Computer Science, 2010
This paper reevaluates the security of GF-NLFSR, a new kind of generalized unbalanced Feistel network structure that was proposed at ACISP 2009. We show that GF-NLFSR itself reveals a very slow diffusion rate, which could lead to several distinguishing attacks.

Generalized Feistel Structures Based on Tweakable Block Ciphers

open access: yesIACR Transactions on Symmetric Cryptology, 2022
A generalized Feistel structure (GFS) is a classical approach to construct a block cipher from pseudorandom functions (PRFs). Coron et al. at TCC 2010 instantiated a Feistel structure with a tweakable block cipher (TBC), and presented its provable ...

Revisiting the shuffle of generalized Feistel structure

open access: yesCybersecurity
The Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

Yoyo Cryptanalysis Against Reduced-Round L-Feistel Structure for Recovering the Secret Components

open access: yesIET Information Security
L-Feistel structure is a new iterative block cipher structure and unifies the Feistel structure and the Lai–Massey structure while maintaining the similarity of encryption and decryption. In this study, we present the first yoyo cryptanalysis against the

On Generalized Feistel Structures Using the Diffusion Switching Mechanism [PDF]

open access: yesIEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008
To design secure blockciphers, estimating immunity against differential attack and linear attack is essential. Recently, Diffusion Switching Mechanism (DSM) is proposed as a design framework to enhance the immunity of Feistel structure against differential attack and linear attack.

A New Cipher Based on Feistel Structure and Chaotic Maps

open access: yesمجلة بغداد للعلوم, 2019
Chaotic systems have been proved to be useful and effective for cryptography. Through this work, a new Feistel cipher depend upon chaos systems and Feistel network structure with dynamic secret key size according to the message size have been proposed ...

A Structural Attack on Type-I Generalized Feistel Networks [PDF]

open access: yesIEEE Access, 2019
This paper presents generic structural cryptanalysis against type-I generalized Feistel networks (GFN), in which all the inner transformations are unknown. The target of our attack is to retrieve all the unknown round functions.
