Cryptanalysis of three matrix-based key establishment protocols [PDF]
, 2011 We cryptanalyse a matrix-based key transport protocol due to Baumslag, Camps, Fine, Rosenberger and Xu from 2006. We also cryptanalyse two recently proposed matrix-based key agreement protocols, due to Habeeb, Kahrobaei and Shpilrain, and due to ...

The complexity of MinRank [PDF]
, 2019 In this note, we leverage some of our results from arXiv:1706.06319 to produce a concise and rigorous proof for the complexity of the generalized MinRank Problem in the under-defined and well-defined case.

Cryptanalysis of Round-Reduced Fantomas, Robin and iSCREAM
Cryptography, 2019 In this work, we focus on LS-design ciphers Fantomas, Robin, and iSCREAM. LS-designs are a family of bitslice ciphers aimed at efficient masked implementations against side-channel analysis.

Algorithms, 2022 There exists a wide range of constraint programming (CP) problems defined on Boolean functions depending on binary variables. One of the approaches to solving CP problems is using specific appropriate solvers, e.g., SAT solvers.

Linear Cryptanalysis of RC5 and RC6 [PDF]
, 1999 In this paper we evaluate the resistance of the block cipher RC5 against linear cryptanalysis. We describe a known plaintext attack that can break RC5-32 (blocksize 64) with 10 rounds and RC5-64 (block-size 128) with 15 rounds. In order to do this we use techniques related to the use of multiple linear approximations.

Distribusi Difference dari S-Box Berbasis Fungsi Balikan Pada GF(28)
Jurnal Matematika, 2016 Substitution-box (s-box) is a basic component of block cipher which performs a substitution. Two powerful cryptanalysis techniques applied to block ciphers are linear cryptanalysis and differential cryptanalysis.

Algebraic Techniques in Linear Cryptanalysis
Proceedings of the 2012 2nd International Conference on Computer and Information Applications (ICCIA 2012), 2012 Linear cryptanalysis is a statistical analysis method. Linear cryptanalysis constructs probabilistic patterns first and then distinguishes the cipher from a random permutation using lots of plaintext-ciphertext pairs. Linear cryptanalysis has a big data complexity. Algebraic attack attempts to exploit the algebraic structure of the cipher by expressing

Security analysis of an encryption scheme based on nonpositional polynomial notations
Open Engineering, 2016 The aim of the research was to conduct a cryptographic analysis of an encryption scheme developed on the basis of nonpositional polynomial notations to estimate the algorithm strength. Nonpositional polynomial notations (NPNs) are residue number systems (

Differential-Linear Cryptanalysis of GIFT family and GIFT-based Ciphers
IACR Commun. Cryptol.At CHES 2017, Banik et al. proposed a lightweight block cipher GIFT consisting of two versions GIFT-64 and GIFT-128. Recently, there are lots of authenticated encryption schemes that adopt GIFT-128 as their underlying primitive, such as GIFT-COFB and ...

Non-Linear Approximations in Linear Cryptanalysis [PDF]
, 1996 By considering the role of non-linear approximatioris in linear cryptanalysis we obtain a generalization of Matsui's linear cryptanalytic techniques. This approach allows Ihe cryptanalyst greater flexibility in mounting a linear cryptanalytic attack and we demonstrate the effectiveness of our non-linear techniques with some simple attacks on LOK191 ...
