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

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

Feistel Networks Made Public, and Applications [PDF]
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]
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.

On Fault Injections in Generalized Feistel Networks [PDF]
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]
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]
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 ...
