Multidimensional linear cryptanalysis with key difference invariant bias for block ciphers

open access: yesCybersecurity, 2021
For block ciphers, Bogdanov et al. found that there are some linear approximations satisfying that their biases are deterministically invariant under key difference. This property is called key difference invariant bias.

Statistical Model of Correlation Difference and Related-Key Linear Cryptanalysis

open access: yesIACR Transactions on Symmetric Cryptology, 2021
The goal of this work is to propose a related-key model for linear cryptanalysis. We start by giving the mean and variance of the difference of sampled correlations of two Boolean functions when using the same sample of inputs to compute both ...

Vectorial Decoding Algorithm for Fast Correlation Attack and Its Applications to Stream Cipher Grain-128a

open access: yesIACR Transactions on Symmetric Cryptology, 2022
Fast correlation attack, pioneered by Meier and Staffelbach, is an important cryptanalysis tool for LFSR-based stream cipher, which exploits the correlation between the LFSR state and key stream and targets at recovering the initial state of LFSR via a ...

Improved linear cryptanalysis on 25‐round SMS4

open access: yesIET 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 ...

Statistical Model on CRAFT

open access: yesChinese 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

open access: yesComputational 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

open access: yesAdvances 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

open access: yesComplexity, 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.
