Due to the quick improvement in digital communications and multimedia applications during
recent periods up to the current time, data protection of digital data such as image, audio …

A Chaos-based cryptosystem is a vital method to enhance information protection in
communication systems. The previous works have addressed this topic either by using …

Abstract High-Efficiency Video Coding (HEVC) is the most recent video codec standard. It is
substantial to analyze the HEVC steganography process due to its practical and academic …

In this paper, a new cryptographic algorithm using a two-dimensional piecewise smooth
nonlinear chaotic map is suggested. It depends on the confusion-diffusion model …

Audio encryption needs critical attention due to an insecure channel in the wireless medium.
This paper presents the first-of-its-kind work addressing a Discrete Wavelet Transform …

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 …

Aiming at the problem that speech information has a strong correlation in adjacent times and
the data type is floating point, the image encryption algorithm of integer type is not suitable …

To ensure the sensitive audio data transmit securely over the insecure internet, we proposed
a chaos based dual-channel audio block encryption algorithm. A 3D chaotic system is …

Considering a nonlinear dynamic oscillator, a high Lyapunov exponent indicates a high
degree of randomness useful in many applications, including cryptography. Most existing …

In this paper, a novel speech encryption algorithm based on hybrid-hyper chaotic system
has presented. Instead of using normal chaotic system a hybrid-hyper chaotic system has …
