Unbalanced Feistel networks and block cipher design [PDF]

open access: yes, 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

Integral Cryptanalysis of WARP based on Monomial Prediction

open access: yesIACR Transactions on Symmetric Cryptology, 2022
WARP is a 128-bit block cipher published by Banik et al. at SAC 2020 as a lightweight alternative to AES. It is based on a generalized Feistel network and achieves the smallest area footprint among 128-bit block ciphers in many settings.

Equivalence of Generalised Feistel Networks

open access: yesIACR Transactions on Symmetric Cryptology
This paper focuses on equivalences between Generalised Feistel Networks (GFN) of type-II. We introduce a new definition of equivalence which captures the concept that two GFNs are identical up to re-labelling of the inputs/outputs, and give a procedure to test this equivalence relation.

Automated Meet-in-the-Middle Attack Goes to Feistel [PDF]

open access: yes, 2023
Feistel network and its generalizations (GFN) are another important building blocks for constructing hash functions, e.g., Simpira v2, Areion, and the ISO standard Lesamnta-LW.

Extended Generalized Feistel Networks Using Matrix Representation [PDF]

open access: yes, 2014
While 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 a new class of such schemes called Extended Generalized Feistel Networks well suited for cryptographic applications.

US–China Trade War: The Effects of Trade Conflict on Brazilian Exports

open access: yesThe World Economy, Volume 49, Issue 6, Page 1293-1313, June 2026.
ABSTRACT Protectionist practices and their implications have been extensively studied in the literature, but few studies have examined the effects of trade competition between two countries on a third country. This paper aims to investigate how a demand shock triggered by China's retaliation against US exports affects Brazil's exports to China.

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF

open access: yesIET Information Security, Volume 2026, Issue 1, 2026.
The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.

Lai-Massey Scheme and Quasi-Feistel Networks [PDF]

open access: yes, 2007
We introduce the notion of quasi-Feistel network, which is generalization of the Feistel network, and contains the Lai-Massey scheme as an instance. We show that some of the works on the Feistel network, including the works of Luby-Rackoff, Patarin, Naor-
