Higher-order differences based research on comparison between type-1 generalized Feistel-SP network and Feistel-SPSP network [PDF]

open access: yesTongxin xuebao, 2014
The powers against the higher-order differential cryptanalysis of the single-SP(substitution-permutation) model and the double-SP model are studied in the type-1 Feistel network by analyzing the growths of algebraic degrees.

Feistel Networks Made Public, and Applications [PDF]

open access: yes, 2007
Feistel Network, consisting of a repeated application of the Feistel Transform, gives a very convenient and popular method for designing "cryptographically strong" permutations from corresponding "cryptographically strong" functions. Up to now, all usages of the Feistel Network, including the celebrated Luby-Rackoff's result, critically rely on (a) the

Improved Security Bounds for Generalized Feistel Networks [PDF]

open access: yesIACR Transactions on Symmetric Cryptology, 2020
We revisit the security of various generalized Feistel networks. Concretely, for unbalanced, alternating, type-1, type-2, and type-3 Feistel networks built from random functions, we substantially improve the coupling analyzes of Hoang and Rogaway (CRYPTO 2010). For a tweakable blockcipher-based generalized Feistelnetwork proposed by Coron et al.

A Novel Chaotic Block Image Encryption Algorithm Based on Deep Convolutional Generative Adversarial Networks

open access: yesIEEE Access, 2021
This paper proposes a novel chaotic block image encryption algorithm based on deep convolutional generative adversarial networks (DCGANs), quaternions, an improved Feistel network, and an overall scrambling and diffusion mechanism.

On Fault Injections in Generalized Feistel Networks [PDF]

open access: yes2014 Workshop on Fault Diagnosis and Tolerance in Cryptography, 2014
In this paper, we propose a generic method to assess the vulnerability to Differential Fault Analysis of generalized Feistel networks (GFN). This method is based on an in-depth analysis of the GFN properties. First the diffusion of faults is studied, both at the block level and at the S-box level, in order to have a fault which maximizes the number of ...

Algebraic Insights into the Secret Feistel Network (Full version) [PDF]

open access: yes, 2021
We introduce the high-degree indicator matrix (HDIM), an object closely related with both the linear approximation table and the algebraic normal form (ANF) of a permutation.

On Generalized Feistel Networks [PDF]

open access: yes, 2010
We prove beyond-birthday-bound security for most of the well-known types of generalized Feistel networks: (1) unbalanced Feistel networks, where the n-bit to m-bit round functions may have n ≠ m; (2) alternating Feistel networks, where the round functions alternate between contracting and expanding; (3) type-1, type-2, and type-3 Feistel networks ...
