Multidimensional Linear Cryptanalysis of Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 This paper presents new generic attacks on Feistel ciphers that incorporate the key addition at the input of the non-invertible round function only.

Multidimensional linear cryptanalysis with key difference invariant bias for block ciphers [PDF]
Cybersecurity, 2021 For block ciphers, Bogdanov et al. found that there are some linear approximations satisfying that their biases are deterministically invariant under key difference. This property is called key difference invariant bias.

Separable Statistics and Multidimensional Linear Cryptanalysis
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

Statistical Model of Correlation Difference and Related-Key Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology, 2021 The goal of this work is to propose a related-key model for linear cryptanalysis. We start by giving the mean and variance of the difference of sampled correlations of two Boolean functions when using the same sample of inputs to compute both ...

IACR Transactions on Symmetric Cryptology, 2022 Fast correlation attack, pioneered by Meier and Staffelbach, is an important cryptanalysis tool for LFSR-based stream cipher, which exploits the correlation between the LFSR state and key stream and targets at recovering the initial state of LFSR via a ...

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 ...

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 ...
