Automated Differential‐Linear Cryptanalysis for AND‐RX Ciphers
IET Information Security, Volume 2024, Issue 1, 2024.Differential and linear cryptanalysis are two important methods to evaluate the security of block ciphers. Building on these two methods, differential‐linear (DL) cryptanalysis was introduced by Langford and Hellman in 1994. This cryptanalytic method has been not only extensively researched but also proven to be effective.

New Practical Attacks on GEA‐1 Based on a New‐Found Weakness
IET Information Security, Volume 2024, Issue 1, 2024.GEA‐1, a proprietary stream cipher, was initially designed and used to protect against eavesdropping general packet radio service (GPRS) between the phone and the base station. Now, a variety of current mobile phones still support this standard cipher.

A new S-box pattern generation based on chaotic enhanced logistic map: case of 5-bit S-box
CybersecurityCryptography plays consistently an essential role in securing any sort of communications or data broadcast over the network. Since the security of any designed block cipher algorithm is related to its Substitution box (S-box), several efforts have been ...

Differential Fault Attacks on Privacy Protocols Friendly Symmetric‐Key Primitives: RAIN and HERA
IET Information Security, Volume 2024, Issue 1, 2024.As the practical applications of fully homomorphic encryption (FHE), secure multi‐party computation (MPC) and zero‐knowledge (ZK) proof continue to increase, so does the need to design and analyze new symmetric‐key primitives that can adapt to these privacy‐preserving protocols.

IET Information Security, Volume 2024, Issue 1, 2024.Differential‐linear (DL) cryptanalysis is an important cryptanalytic method in cryptography and has received extensive attention from the cryptography community since its proposal by Langford and Hellman in 1994. At CT‐RSA 2023, Bellini et al. introduced continuous difference propagations of XOR, rotation, and modulo‐addition operations and proposed a ...

MRHS solver based on linear algebra and exhaustive search
Journal of Mathematical Cryptology, 2018 We show how to build a binary matrix from the MRHS representation of a symmetric-key cipher. The matrix contains the cipher represented as an equation system and can be used to assess a cipher’s resistance against algebraic attacks.

Algebraic Cryptanalysis of Deterministic Symmetric Encryption
, 2015 Deterministic symmetric encryption is widely used in many cryptographic applications. The security of deterministic block and stream ciphers is evaluated using cryptanalysis. Cryptanalysis is divided into two main categories: statistical cryptanalysis and algebraic cryptanalysis.

HHL Algorithm for Tensor-Decomposable Matrices
Quantum ReportsWe use the HHL algorithm to retrieve a quantum state holding the algebraic normal form (ANF) of a Boolean function. Unlike the standard HHL applications, we do not describe the cipher as an exponentially big system of equations.
