Separable Statistics and Multidimensional Linear Cryptanalysis [PDF]

, 2017
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 encryption internal bits.

Integral and Multidimensional Linear Distinguishers with Correlation Zero

, 2012
Zero-correlation cryptanalysis uses linear approximations holding with probability exactly 1/2. In this paper, we reveal fundamental links of zero-correlation distinguishers to integral distinguishers and multidimensional linear distinguishers.

On invariant zeros of linear systems of PDEs [PDF]

, 2006
In this paper we provide a behavioral framework in which to describe and extend the concept of linear dynamics introduced by Fliess, from the one dimensional (1D) to the multidimensional (nD) framework.We provide an alternative description of the ...

Improved Linear Cryptanalysis of Reduced-Round MIBS [PDF]

, 2014
MIBS is a 32-round lightweight block cipher with 64-bit block size and two different key sizes, namely 64-bit and 80-bit keys. Bay et al. provided the first impossible differential, differential and linear cryptanalyses of MIBS.

Links between differential and linear cryptanalysis

, 2006
Linear cryptanalysis, introduced in 1994 by Matsui, will most certainly open-up the way to new attack methods which may be made more efficient when compared or combined with differential cryptanalysis. This paper exhibits new relations between linear and

Improved Linear Cryptanalysis of Reduced-round SIMON [PDF]

, 2014
SIMON is a family of ten lightweight block ciphers published by Beaulieu et al.\ from U.S. National Security Agency (NSA). In this paper we investigate the security of SIMON against different variants of linear cryptanalysis techniques, i.e.\ classical ...

Differential-linear and related key cryptanalysis of round-reduced scream

, 2018
We have analysed tweakable block cipher Scream which is used by cipher SCREAM, with the techniques linear cryptanalysis, differential cryptanalysis and related key cryptanalysis. Tweakable block cipher Scream is already analysed with linear, differential-

Zero-Correlation Linear Cryptanalysis of Reduced-Round SIMON

, 2015
In June 2013, the U.S. National Security Agency proposed two families of lightweight block ciphers, called SIMON and SPECK respectively. These ciphers are designed to perform excellently on both hardware and software platforms.

New Links Between Differential and Linear Cryptanalysis [PDF]

, 2015
Recently, a number of relations have been established among previously known statistical attacks on block ciphers. Leander showed in 2011 that statistical saturation distinguishers are on average equivalent to multidimensional linear distinguishers ...

Links Between Differential and Linear Cryptanalysis

, 1994
Linear cryptanalysis, introduced last year by Matsui, will most certainly open-up the way to new attack methods which may be made more efficient when compared or combined with differential cryptanalysis.
