As the application of multimedia technology intensifies recently, more and more attention
has been paid to privacy protection in image data. The interest in DNA-based image …

In this paper, two efficient cryptosystem schemes in the form of permutation–substitution
based on chaotic systems are proposed. Firstly, a simple and efficient S-box method is …

In this paper, an image cryptosystem based on genetic central dogma (GCD), Knuth–Morria–
Pratt (KMP) algorithm and a chaotic system is developed. The KMP algorithm is firstly used …

Millions of confidential images are transmitted every day by people through the multimedia
systems of the internet. Such confidential information in the images may be belong to the …

An image encryption scheme is proposed using high-dimensional chaotic systems and cycle
operation for DNA sequences. In the scheme, the pixels of the original image are encoded …

This paper proposes a new one-dimensional chaotic map, called chaotic coupled Sine map
(CCSM), for the scrambling and encryption processes. The purpose of the CCSM design is …

In this paper, a novel image encryption algorithm based on genetic recombination and hyper-
chaotic system is proposed. The basic rules of genetic recombination are employed to …

By combining chaotic system and DNA sequence operations, an image cryptosystem is
proposed. To generate sequences with better chaotic characteristics, a new spatiotemporal …

In recent years, a variety of chaos-based image cryptosystems have been investigated to
meet the increasing demand for real-time secure image transmission. Most of them are …

At the present time, the protection of multimedia data has become a very important process
which can be achieved by encryption. Basically, so many different techniques have been …
