Cryptosystem Identification Scheme Based on ASCII Code Statistics
Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020 In the field of information security, block cipher is widely used in the protection of messages, and its safety naturally attracts people’s attention. The identification of the cryptosystem is the premise of encrypted data analysis. It belongs to the category of attack analysis in cryptanalysis and has important theoretical significance and application

A New Technique for Multidimensional Linear Cryptanalysis with Applications on Reduced Round Serpent [PDF]
, 2009 In this paper, we present a new technique for Matsui's algorithm 2 using multidimensional linear approximation. We show that the data complexity of the attack can be reduced significantly by our method even when the linear hull effect is present. We apply our method to the key recovery attack on 5-round Serpent and demonstrate that our attack is ...

Femtosecond‐Laser‐Induced Physical Unclonable Random Maze Structure for Storage‐Free Encryption
Advanced Science, EarlyView.Femtosecond‐laser‐induced gold random maze structures serve as multimodal physical unclonable functions for storage‐free encryption. Their stochastic optical, electrical, and Raman responses are generated by plasmon‐assisted Marangoni formation and converted into AES‐compatible keys without permanent secret‐key storage, offering a portable route toward

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security
IET Image Processing, Volume 20, Issue 1, January/December 2026.The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

Complexity, Volume 2024, Issue 1, 2024.Image encryption schemes are predominantly software‐based. Only a select few have been implemented in real‐life communication systems. This paper introduces a novel chaotic image encryption scheme based on a modified Z‐order curve, a modified Josephus problem, and an improved Vigenère cipher–based ribonucleic acid (RNA) operation. It is implemented and
