Improving the Algorithm 2 in Multidimensional Linear Cryptanalysis

Lecture Notes in Computer Science, 2011
In FSE'09 Hermelin et al. introduced the Algorithm 2 of multidimensional linear cryptanalysis. If this algorithm is m-dimensional and reveals l bits of the last round key with N plaintext-ciphertext pairs, then its time complexity is O(mN2l). In this paper, we show that by applying the Fast Fourier Transform and Fast Walsh Hadamard Transform to the ...

Multidimensional Zero-Correlation Linear Cryptanalysis on 23-Round LBlock-s

Lecture Notes in Computer Science, 2016
LBlock-s is the kernel block cipher of the authentication encryption algorithm LAC submitted to CAESAR competition. The LBlock-s algorithm is almost the same as LBlock except that the former adopts an improved key schedule algorithm with better diffusion property. Using the shifting relation of certain subkeys derived by the new key schedule algorithm,

Multidimensional Zero-Correlation Linear Cryptanalysis on PRINCE

2017
The PRINCE is a light-weight block cipher with the 64-bit block size and 128-bit key size. It is characterized by low power-consumption and low latency. PRINCEcore is the PRINCE cipher without key-whiting. For evaluating its security, a statistical testing on linear transformation is performed, and a statistical character matrix is given. By using the “

Multidimensional Linear Cryptanalysis of Reduced Round Serpent

2008
Various authors have previously presented different approaches how to exploit multiple linear approximations to enhance linear cryptanalysis. In this paper we present a new truly multidimensional approach to generalise Matsui's Algorithm 1. We derive the statistical framework for it and show how to calculate multidimensional probability distributions ...

Multidimensional Zero-Correlation Linear Cryptanalysis of E2

2014
E2 is a block cipher designed by NTT and was a first-round AES candidate. E2’s design principles influenced several more recent block ciphers including Camellia, an ISO/IEC standard cipher. So far the cryptanalytic results for round-reduced E2 have been concentrating around truncated and impossible differentials.

Multidimensional Zero-Correlation Linear Cryptanalysis of Reduced Round SPARX-128

2017
SPARX is a family of ARX-based block ciphers proposed at ASIACRYPT 2016. This family was designed with the aim of providing provable security against single-characteristic linear and differential cryptanalysis. SPARX-128/128 and SPARX-128/256 are two members of this family which operate on data blocks of length 128 bits and keys of length 128 and 256 ...
