A simple network of small s-boxes can be proven secure against differential and linear cryptanalysis. Upperbounds of the differential probabilities and the linear correlations are derived for a generalized Feistel network having 1, 2, 3 or 4 s-boxes in parallel per round. It is conjectured that the results hold in general.

Improved Attacks on Extended Generalized Feistel Networks
2016In SAC 2013, Berger et al. defined Extended Generalized Feistel Networks (EGFN) and analyzed their security. They proposed designs with 8 or 16 branches. This class of schemes is well-suited for cryptographic applications. Using the minimal number of active S-boxes, the authors showed that for 64-bits messages divided into 8 branches, at least seven ...

Double SP-Functions: Enhanced Generalized Feistel Networks
2011This work deals with the security and efficiency of type-I and type-II generalized Feistel networks (GFNs) with 4 lines. We propose to instantiate the GFNs with double SP-functions (substitutionpermutation layer followed by another substitution-permutation layer) instead of single SP-functions (one substitution-permutation layer).

Provable Related-Key Security of Contracting Feistel Networks
2021We continue the line of works constructing related-key secure PRFs (Bellare and Cash, CRYPTO 2010) and PRPs (Barbosa and Farshim, FSE 2014). In detail, we consider generalized Feistel networks using contracting round functions from \(\{0,1\}^m\) to \(\{0,1\}^n\), and explore conditions that are sufficient for such Contracting Feistel Networks (CFNs) to

Utilizing LFSR and Feistel networks in image encryption
2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013This paper presents a new encryption scheme based on the combination between Linear Feedback Shift Register (LFSR) and generalized Feistel networks (GFN). The construction of each GFN depends on Substitution Boxes (S-Boxes) and its operation requires a key. The encryption key length is dynamic and can be controlled via the initial values of the LFSR, S-

Generic Attacks on Feistel Networks with Internal Permutations
2009In this paper, we describe generic attacks on Feistel networks with internal permutations, instead of Feistel networks with internal functions as designed originally. By generic attacks, we mean that in these attacks the internal permutations are supposed to be random.
