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-

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 ...

Throwing Boomerangs into Feistel Structures
IACR Transactions on Symmetric Cryptology, 2022 Automatic tools to search for boomerang distinguishers have seen significant advances over the past few years. However, most previous work has focused on ciphers based on a Substitution Permutation Network (SPN), while analyzing the Feistel structure is

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.

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.

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.

Generalized Feistel Structures Based on Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2022 A generalized Feistel structure (GFS) is a classical approach to construct a block cipher from pseudorandom functions (PRFs). Coron et al. at TCC 2010 instantiated a Feistel structure with a tweakable block cipher (TBC), and presented its provable ...

New Genetic Operators for Developing S-Boxes With Low Boomerang Uniformity
IEEE Access, 2022 The boomerang uniformity measures the resistance of block ciphers to boomerang attacks and has become an essential criterion of the substitution box (S-box).

IEEE Access, 2021 Machine learning has recently started to gain the attention of cryptographic researchers, notably in block cipher cryptanalysis. Most of these machine learning-based approaches are black box attacks that are cipher-specific.
