Improved linear cryptanalysis on 25‐round SMS4
IET Communications, Volume 16, Issue 14, Page 1643-1653, August 2022., 2022 Abstract SMS4 is the Chinese national standard for WLAN, which is also an ISO/IEC international standard. This paper presents a linear cryptanalysis on 25‐round SMS4 for the first time. Firstly, this paper adopts a new statistic in linear cryptanalysis, which is aimed to compute the distance between one cipher system and one random permutation, which ...

The Key-Dependent Capacity in Multidimensional Linear Cryptanalysis
The Computer Journal, 2021 AbstractThe capacity is an important parameter in multidimensional linear attack. In this paper, we firstly explore the distribution of the key-dependent capacity. Based on the magnitude of the correlation contributions, we divide the linear approximations subspace into two sets: one set consists of the strong linear approximations, and the other set ...

Chinese Journal of Electronics, Volume 31, Issue 4, Page 698-712, July 2022., 2022 Many cryptanalytic techniques for symmetric‐key primitives rely on specific statistical analysis to extract some secrete key information from a large number of known or chosen plaintext‐ciphertext pairs. For example, there is a standard statistical model for differential cryptanalysis that determines the success probability and complexity of the attack

A Blockchain‐Based Verifiable User Data Access Control Policy for Secured Cloud Data Storage
Computational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022 Adding the adequate level of security of information systems dealing with sensitive data, privacy, or defense systems involves some form of access control. The audits performed are dealing with the determination of the allowed activities of the legal users, when attempting to access resources of the system.

[Retracted] Deep Learning‐Based English‐Chinese Translation Research
Advances in Meteorology, Volume 2022, Issue 1, 2022., 2022 Neural machine translation (NMT) has been bringing exciting news in the field of machine translation since its emergence. However, because NMT only employs single neural networks to convert natural languages, it suffers from two drawbacks in terms of reducing translation time: NMT is more sensitive to sentence length than statistical machine ...

Fast and Robust Image Encryption Scheme Based on Quantum Logistic Map and Hyperchaotic System
Complexity, Volume 2022, Issue 1, 2022., 2022 Topic of quantum chaos has begun to draw increasing attention in recent years. So, to ensure the security of digital image, an image encryption algorithm based on combining a hyperchaotic system and quantum 3D logistic map is proposed. This algorithm is applied in four stages.

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 ...

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
