Hardware security and trust have become a pressing issue during the last two decades due
to the globalization of the semiconductor supply chain and ubiquitous network connection of …

Since the early 1990s, a large number of chaos-based communication systems have been
proposed exploiting the properties of chaotic waveforms. The motivation lies in the …

This paper announces a novel three-dimensional chaotic system with line equilibrium and
discusses its dynamic properties such as Lyapunov exponents, phase portraits, equilibrium …

In this study, an encryption algorithm that uses chaos based S-BOX is developed for secure
and speed image encryption. First of all, a new chaotic system is developed for creating S …

In this paper, a new and efficient pixel-level image encryption algorithm is presented. In
contrast to the traditional permutation–diffusion architecture, the proposed method enhances …

Abstract Substitution Box (S-Box) is one of the most significant structures used to create an
encryption which is strong and resistant against attacks in block encryption algorithms. S …

With the rapid development of communication technology and the popularization of network,
information security has been highly valued by all walks of life. Random numbers are used …

There has recently been an increase in the number of new chaotic system designs and
chaos-based engineering applications. In this study, since homoclinic and heteroclinic orbits …

In this paper we investigate a new system of three coupled nonlinear ordinary differential
equations, whose dynamics support periodic and chaotic attractors as certain parameters …

Pseudorandom numbers are widely used in information encryption, spread spectrum
communication and other science and technology and engineering fields. Because chaos is …
