Chaos has been one of the most effective cryptographic sources since it was first used in
image-encryption algorithms. This paper closely examines the development process of …

Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

This article creatively proposes a class of sorting matrices with fractal characteristics, named
the fractal sorting matrix (FSM), and introduces its iterative calculation method. The FSM is …

The neuron models have been widely applied to neuromorphic computing systems and
chaotic circuits. However, discrete neuron models and their application in image encryption …

Digital images play a crucial role in modern communication, but the accompanying privacy
concerns have become increasingly prominent. In this context, image encryption technology …

Because the characteristics of chaotic systems are very consistent with the requirements of
cryptosystem, chaotic systems are widely used in the encryption of big data, especially the …

This paper studies chaotic image encryption technology and an application of matrix semi-
tensor product theory, and a Boolean network encryption algorithm for a synchronous …

In this paper, a chaotic image encryption algorithm based on the matrix semi-tensor product
(STP) with a compound secret key is designed. First, a new scrambling method is designed …

This paper proposes a new hybrid chaotic map and a different way of using optimization
technique to improve the performance of encryption algorithms. Compared to other chaotic …

In this paper, a fractional-order hyperchaotic detuned laser system (FHDLS) is proposed,
and a novel image cryptosystem with high-security performance is designed by combining …
