Multidimensional Linear Cryptanalysis of Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 This paper presents new generic attacks on Feistel ciphers that incorporate the key addition at the input of the non-invertible round function only.

Truncated Differential Attacks on Contracting Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2022 We improve truncated differential attacks on t-branch contracting Feistel ciphers with a domain size of Nt. Based on new truncated differentials, a generic distinguisher for t2 + t − 2 rounds using O(Nt−1) data and time is obtained.

On Boomerang Attacks on Quadratic Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 The recent introduction of the Boomerang Connectivity Table (BCT) at Eurocrypt 2018 revived interest in boomerang cryptanalysis and in the need to correctly build boomerang distinguishers.

SIPFA: Statistical Ineffective Persistent Faults Analysis on Feistel Ciphers
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Persistent Fault Analysis (PFA) is an innovative and powerful analysis technique in which fault persists throughout the execution. The prior prominent results on PFA were on SPN block ciphers, and the security of Feistel ciphers against this attack has ...

On the resistance of new lightweight block ciphers against differential cryptanalysis [PDF]
Heliyon, 2023 Many recently proposed lightweight block ciphers lack security evaluation against generic cryptanalytic attacks such as differential cryptanalysis. In this paper, we contribute towards security evaluation efforts by investigating four lightweight Feistel-

Complementing Feistel Ciphers [PDF]
Fast Software Encryption Workshop, 2013 In this paper, we propose related-key differential distinguishers based on the complementation property of Feistel ciphers. We show that with relaxed requirements on the complementation, i.e. the property does not have to hold for all keys and the complementation does not have to be on all bits, one can obtain a variety of distinguishers.

Feistel Ciphers - Security Proofs and Cryptanalysis
, 2017 International audience ; This book provides a survey on different kinds of Feistel ciphers, with their definitions and mathematical/computational properties. Feistel ciphers are widely used in cryptography in order to obtain pseudorandom permutations and secret-key block ciphers. In Part 1, we describe Feistel ciphers and their variants. We also give a
