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.

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

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 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.

A Key Selected S‐Box Mechanism and Its Investigation in Modern Block Cipher Design
Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020 The block cipher is an important means to provide data confidentiality in reality, and the S‐box is an essential part in most of modern block cipher designs. In 1973, Feistel used a key selected S‐box mechanism in his early block cipher designs, whose idea is to let each S‐box have two different states and use a key bit to select which of the two ...
