Over the years, there has been considerable interest in the area of chaos-based encryption
due to the fact that cryptographic algorithms and chaotic maps share a wide-range of similar …

In the Internet of Things (IoT), a lot of constrained devices are interconnected. The data
collected from those devices can be the target of cyberattacks. In this paper, a lightweight …

Considering the current dependency on digital technology in modern society, the protection
of multimedia is highly important. Encryption is vital in modern digital communication …

In this paper, multilayer cryptosystems for encrypting audio communications are proposed.
These cryptosystems combine audio signals with other active concealing signals, such as …

Transmission and storage of medical data using cloud-based Internet-of-health-systems
(IoHS) necessitate important prerequisites, such as secrecy, legitimacy, and integrity. This …

Currently, chaotic cryptography is mainly concentrated on image encryption. Once-popular
stream-encryption algorithms, eg, textual data, are now rarely considered. This article …

This article presents a novel four-dimensional autonomous fractional-order chaotic system
(FOCS) with multi-nonlinearity terms. Several dynamics, such as the chaotic attractors …

In consideration of the reduced chaotic range and susceptibility of a single chaotic map, we
exploit the 4D-hyperchaotic system for creating three S-boxes ie, red, green and blue S …

Multimedia information usage is increasing with new technologies such as the Internet of
things (IoT), cloud computing, and big data processing. Video is one of the most widely used …

Issues such as inefficient encryption architectures, nonstandard formats of image datasets,
weak randomness of chaos‐based Pseudorandom Number Generators (PRNGs), omitted S …
