Because of the COVID-19 pandemic, most of the tasks have shifted to an online platform.
Sectors such as e-commerce, sensitive multi-media transfer, online banking have …

With the widespread adoption of smart devices and high-speed networks, investigators are
focusing on securing digital image applications, such as those on social media, in …

Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

In this paper, we introduce a novel color image encryption algorithm based on DNA
sequence operations, one-time keys and the spatiotemporal chaos. Firstly, the key streams …

In this paper, synchronization of an inertial neural network with time-varying delays is
investigated. Based on the variable transformation method, we transform the second-order …

In this paper, we propose a novel image encryption algorithm based on a hybrid model of
deoxyribonucleic acid (DNA) masking, a Secure Hash Algorithm SHA-2 and the Lorenz …

This paper proposes a new encryption scheme for color images based on Deoxyribonucleic
acid (DNA) sequence operations and multiple improved one-dimensional (1D) chaotic …

This paper is mainly concerned with the synchronization problem of reaction-diffusion neural
networks (RDNNs) with delays and its direct application in image secure communications …

A novel image encryption scheme employing the memristive hyperchaotic system, cellular
automata (CA) and DNA sequence operations is presented, which consists of diffusion …

This paper introduces an extended Lü system with coexisting attractors. The number and
stability of equilibria are determined. The coexisting attractors of the system are displayed by …
