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 …

This paper proposes a new tent-multi dynamic piecewise coupled mapping lattice
(TMDPCML). Through the comprehensive analysis of the performance test results …

The classical random walk formalism plays an important role in a wide range of applications.
Its quantum counterpart, the quantum walk, is proposed as an important theoretical model …

Due to the advancements in 5 G technologies, high-definition, and the internet of things
(IoT), the capacity demand of optical networks has been exponentially increased. Optical …

In this work, we first present a modified version of the traditional logistic chaotic map. The
proposed version contains an additional parameter that is used to increase the security level …

Quantum mechanisms can provide strong security in image processing against the
disadvantages of pseudorandom and periodic of traditional chaotic systems. Based on its …

Multistability and symmetry breaking have been significantly investigated recently. In this
paper, we study the effects of symmetry breaking on the behavior of a particular class of …

Abstract Information security and image encryption have rapidly developed in recent years.
This study presents an iterative method for vectors with fractal characteristics. Based on the …

In order to ensure reliable and secure image exchange, chaotic systems are often
considered for their good performance in information security. In this work, we first propose …

Image encryption is an effective way to protect image data. However, existing image
encryption algorithms are still unable to strike a good balance between security and …
