Zero‐Correlation Linear Cryptanalysis on SPARX‐64
Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 SPARX is a family of ARX‐based block ciphers designed according to the long‐trail strategy, which has 32‐bit ARX‐based SBoxes and has provable bounds against single‐differential and single‐linear cryptanalysis. Since its proposation, some third‐party cryptanalysis methods have been presented. As far as we know, the best attacks against SPARX‐64 covered

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 ...

Computational Image Encryption Techniques: A Comprehensive Review
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Images contain very sensitive and confidential information. Because images play a significant role in many applications such as military communication, remote‐sensing, and medical‐imaging, therefore, it is necessary to protect sensitive and confidential information from unauthorized use and modification.

Image Processing Method Based on Chaotic Encryption and Wavelet Transform for Planar Design
Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021 This paper provides an in‐depth study and analysis of image processing for graphic design through chaotic encryption combined with a wavelet transform algorithm. Firstly, the traditional Mallat algorithm is optimized; since the mean value of the transform coefficients generated after the wavelet transform of the image is used as the initial value of ...

IMPROVED POLYNOMIAL-TIME PLAINTEXT-RECOVERY ATTACK ON THE MATRIX-BASED KNAPSACK CIPHER
Радіоелектронні і комп'ютерні системи, 2020 Asymmetric ciphers are widely used to ensure the confidentiality of data transmission via insecure channels. These cryptosystems allow the interacting parties to create a shared secret key for a symmetric cipher in such a way that an eavesdropper gets no

Statistical Tests for Key Recovery Using Multidimensional Extension of Matsui\u27s Algorithm 1 [PDF]
, 2009 In one dimension, there is essentially just one binomially distributed statistic, bias or correlation, for testing correctness of a key bit in Matsui\u27s Algorithm 1. In multiple dimensions, different statistical approaches for finding the correct

Improved Parameter Estimates for Correlation and Capacity Deviates in Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology, 2017 Statistical attacks form an important class of attacks against block ciphers. By analyzing the distribution of the statistics involved in the attack, cryptanalysts aim at providing a good estimate of the data complexity of the attack.
