Recently, chaotic maps have been considered to design pseudorandom number generator
(PRNG). However, some chaotic maps present security disadvantages, such as low …

To protect image data privacy, a secure and fast image encryption algorithm using hyper-
chaos based key generator and vector operation is proposed. Firstly, we introduce a novel …

In this work, we describe the model of a new 5-D hyperchaotic system with three positive
Lyapunov exponents. Since the maximum positive Lyapunov exponent of the proposed …

A true random number generator (TRNG) is essential to ensure information security for
Internet of Things (IoT) edge devices. While pseudorandom number generators (PRNGs) …

Cyberattacks pose a serious threat to the wireless transfer of sensitive healthcare data,
hampering the level of privacy offered. Numerous cyber-security modules have been …

The information stored or shared via the internet is growing massively and includes images
primarily. The images are vulnerable to attacks when transferred over the internet as they …

The ultimate focus of this paper is to provide a hyperchaos-based reconfigurable platform for
the real-time securing of communicating embedded systems interconnected in networks …

In a rapidly advancing world of technology, information security studies have become the
backbone of the digital age, and steps in this area are critical. In this context, cryptography …

A novel image encryption algorithm using a combination of 4D discrete hyperchaotic map
and DNA encoding is proposed in this work. The used 4D discrete hyperchaotic map has a …
