Boosting Differential-Linear Cryptanalysis of ChaCha7 with MILP

IACR Transactions on Symmetric Cryptology, 2023
In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new differential-linear distinguishers that we were able to build thanks to the following improvements: a) we considered a ...

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.

Multidimensional linear cryptanalysis [PDF]

, 2010
Linear cryptanalysis is an important tool for studying the security of symmetric ciphers. In 1993 Matsui proposed two algorithms, called Algorithm 1 and Algorithm 2, for recovering information about the secret key of a block cipher.

Differential-Linear Cryptanalysis of Reduced Round ChaCha

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-

Linear Cryptanalysis of Reduced-Round Simon Using Super Rounds

Cryptography, 2020
We present attacks on 21-rounds of Simon 32/64, 21-rounds of Simon 48/96, 25-rounds of Simon 64/128, 35-rounds of Simon 96/144 and 43-rounds of Simon 128/256, often with direct recovery of the full master key without repeating the attack over multiple ...

Multidimensional Linear Cryptanalysis of AEGIS

IACR Transactions on Symmetric Cryptology
AEGIS is a family of authenticated encryption with associated data (AEAD) ciphers that target for highly efficient implementations in software. The main operation in AEGIS is the AES encryption round function such that it can make full use of the ...

Improved Parameter Estimates for Correlation and Capacity Deviates in Linear Cryptanalysis [PDF]

IACR Transactions on Symmetric Cryptology, 2017
Statistical attacks form an important class of attacks against block ciphers. By analyzing the distribution of the statistics involved in the attack, cryptanalysts aim at providing a good estimate of the data complexity of the attack.

Theoretical Linear Cryptanalysis of the 5G Standard Candidate SNOW 5G

IACR Transactions on Symmetric Cryptology
In this paper, we perform linear cryptanalysis of the stream cipher SNOW 5G, which is recommended by the international standardization group (SAGE) as one standard algorithm for 5G confidentiality and integrity protection over the wireless channel. SNOW
