Differential-Linear Cryptanalysis and Cube Attacks on ChiLow [PDF]

IACR Transactions on Symmetric Cryptology
ChiLow is a family of tweakable block ciphers specifically designed for embedded code encryption, proposed at EUROCRYPT 2025. Its novel nested tweakkey schedule and a variant of the χ function significantly enhance latency and energy efficiency.

Differential-Linear Cryptanalysis of Reduced Round ChaCha [PDF]

IACR Transactions on Symmetric Cryptology
ChaCha is a well-known stream cipher that has been used in many network protocols and software. In this paper, we study the security of reduced round ChaCha. First, by considering the differential-linear hull effect, we improve the correlation of a four-

Quantum Differential and Linear Cryptanalysis [PDF]

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.

Differential-linear and Impossible Differential Cryptanalysis of Round-reduced Scream [PDF]

Proceedings of the 14th International Joint Conference on e-Business and Telecommunications, 2017
In this work we focus on the tweakable block cipher Scream, We have analysed Scream with the techniques, which previously have not been applied to this algorithm, that is differential-linear and impossible differential cryptanalysis. This is work in progress towards a comprehensive evaluation of Scream.

DLCT: A New Tool for Differential-Linear Cryptanalysis [PDF]

, 2019
Differential cryptanalysis and linear cryptanalysis are the two best-known techniques for cryptanalysis of block ciphers. In 1994, Langford and Hellman introduced the differential-linear (DL) attack based on dividing the attacked cipher E into two subciphers \(E_0\) and \(E_1\) and combining a differential characteristic for \(E_0\) with a linear ...

Improved Differential-Linear Cryptanalysis of 7-Round Chaskey with Partitioning [PDF]

, 2016
In this work we study the security of Chaskey, a recent lightweight MAC designed by Mouha et al., currently being considered for standardization by ISO/IEC and ITU-T. Chaskey uses an ARX structure very similar to SipHash. We present the first cryptanalysis of Chaskey in the single user setting, with a differential-linear attack against 6 and 7 rounds ...

Automated Differential-Linear Cryptanalysis for AND-RX Ciphers

IET Information Security
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

Differential-Linear Cryptanalysis of GIFT family and GIFT-based Ciphers [PDF]

IACR Communications in Cryptology
At CHES 2017, Banik et al. proposed a lightweight block cipher GIFT consisting of two versions GIFT-64 and GIFT-128. Recently, there are lots of authenticated encryption schemes that adopt GIFT-128 as their underlying primitive, such as GIFT-COFB and HyENA.

Security against differential and linear cryptanalysis for general SPT models [PDF]

Tongxin xuebao, 2012
To use SP network in stream ciphers safely and efficiently,the ability against differential and linear cryptanalysis of SPT models was studied,where S and T denote different layers for substitution,in which compression could be achieved,and P denotes the

Improved machine learning-aided linear cryptanalysis: application to DES [PDF]

Cybersecurity
In CRYPTO 2019, Gohr built a bridge between machine learning and differential cryptanalysis, which show that machine learning-aided methods have advantages over classical differential cryptanalysis.
