Separable Statistics and Multidimensional Linear Cryptanalysis [PDF]
IACR Transactions on Symmetric Cryptology, 2018 Multidimensional linear cryptanalysis of block ciphers is improved in this work by introducing a number of new ideas. Firstly, formulae is given to compute approximate multidimensional distributions of the encryption algorithm internal bits. Conventional

Multidimensional Linear Cryptanalysis of AEGIS
IACR Transactions on Symmetric CryptologyAEGIS 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 ...

On Multidimensional Linear Cryptanalysis [PDF]
, 2010 Matsui's Algorithms 1 and 2 with multiple approximations have been studied over 16 years. In CRYPTO'04, Biryukov et al. proposed a formal framework based on m statistically independent approximations. Started by Hermelin et al. in ACISP'08, a different approach was taken by studying m-dimensional combined approximations from m base approximations ...

Multivariate Profiling of Hulls for Linear Cryptanalysis [PDF]
IACR Transactions on Symmetric Cryptology, 2018 Extensions of linear cryptanalysis making use of multiple approximations, such as multiple and multidimensional linear cryptanalysis, are an important tool in symmetric-key cryptanalysis, among others being responsible for the best known attacks on ...

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.

The Key-Dependent Capacity in Multidimensional Linear Cryptanalysis
The Computer Journal, 2021 AbstractThe capacity is an important parameter in multidimensional linear attack. In this paper, we firstly explore the distribution of the key-dependent capacity. Based on the magnitude of the correlation contributions, we divide the linear approximations subspace into two sets: one set consists of the strong linear approximations, and the other set ...

Zero‐Correlation Linear Cryptanalysis on SPARX‐64
Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 SPARX is a family of ARX‐based block ciphers designed according to the long‐trail strategy, which has 32‐bit ARX‐based SBoxes and has provable bounds against single‐differential and single‐linear cryptanalysis. Since its proposation, some third‐party cryptanalysis methods have been presented. As far as we know, the best attacks against SPARX‐64 covered

IMPROVED POLYNOMIAL-TIME PLAINTEXT-RECOVERY ATTACK ON THE MATRIX-BASED KNAPSACK CIPHER
Радіоелектронні і комп'ютерні системи, 2020 Asymmetric ciphers are widely used to ensure the confidentiality of data transmission via insecure channels. These cryptosystems allow the interacting parties to create a shared secret key for a symmetric cipher in such a way that an eavesdropper gets no
