Higher-Order Differential-Linear Cryptanalysis of ChaCha Stream Cipher

IEEE Access
This paper studies the advanced methodologies of differential cryptanalysis with a particular emphasis on higher-order differentials and higher-order differential-linear cryptanalysis, along with their application to the ChaCha stream cipher.

Mixture Differential Cryptanalysis: a New Approach to Distinguishers and Attacks on round-reduced AES

IACR Transactions on Symmetric Cryptology, 2018
At Eurocrypt 2017 the first secret-key distinguisher for 5-round AES - based on the “multiple-of-8” property - has been presented. Although it allows to distinguish a random permutation from an AES-like one, it seems rather hard to implement a key ...

Commutative cryptanalysis as a generalization of differential cryptanalysis

Designs, Codes and Cryptography
Abstract Recently, Baudrin et al. analyzed a special case of Wagner’s commutative diagram cryptanalysis, referred to as commutative cryptanalysis. For a family $$(E_k)_k$$ ( E

Related-Key Differential Cryptanalysis of the Reduced-Round Block Cipher GIFT

IEEE Access, 2019
GIFT is a lightweight block cipher that was proposed by Banik et al. at CHES 2017, which is said to be a direct improvement over PRESENT since “that provides a much increased efficiency in all domains (smaller and faster)” and improves the ...

Quantum Differential and Linear Cryptanalysis

IACR Transactions on Symmetric Cryptology, 2016
Quantum computers, that may become available one day, would impact many scientific fields, most notably cryptography since many asymmetric primitives are insecure against an adversary with quantum capabilities.

A New (Related-Key) Neural Distinguisher Using Two Differences for Differential Cryptanalysis [PDF]

IET Information Security
At CRYPTO 2019, Gohr showed the significant advantages of neural distinguishers over traditional distinguishers in differential cryptanalysis. At fast software encryption (FSE) 2024, Bellini et al.

Differential Cryptanalysis and Boomerang Cryptanalysis of LBlock [PDF]

, 2013
LBlock is a lightweight block cipher proposed in ACNS 2011. It has a 64-bit block size and 80-bit key size which is the typical parameter setting accepted by most of the recent proposed lightweight block ciphers. It has fast hardware implementation efficiency and it still remains rather secure considering the recent results and the security margin it ...

XSL Block Ciphers’ Key-schedules with Resistance to Differential Cryptanalysis

Безопасность информационных технологий, 2014
The paper discusses the resistance of XSL block ciphers to differential cryptanalysis. AES-like block ciphers with alternative key-schedules (increased performance and density) are given as an example.

Linear and differential cryptanalysis: Another viewpoint

Математические вопросы криптографии, 2020
Доказаны теоремы о точных значениях линейной и разностной характеристик. Приведен пример универсальной функциональной схемы, который показывает, что обычные методы оценки характеристик вероятностных соотношений могут приводить к значительным ошибкам.
