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

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 ...

Protecting Against Multidimensional Linear and Truncated Differential Cryptanalysis by Decorrelation [PDF]

Lecture Notes in Computer Science, 2015
The decorrelation theory provides a different point of view on the security of block cipher primitives. Results on some statistical attacks obtained in this context can support or provide new insight on the security of symmetric cryptographic primitives.

Analysis of Diffusion Properties in Generalized Feistel Ciphers Under Multidimensional Linear Cryptanalysis

IACR Transactions on Symmetric Cryptology
This paper presents a unified framework for generic attacks on Generalized Feistel Ciphers, with a primary focus on Type 1, Type 2, and unbalanced contracting (U-Type 1) Feistel constructions with non-invertible round functions.

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 ...

Vectorial Decoding Algorithm for Fast Correlation Attack and Its Applications to Stream Cipher Grain-128a

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 ...
