Chaos has been one of the most effective cryptographic sources since it was first used in
image-encryption algorithms. This paper closely examines the development process of …

The exponential growth in transmission of multimedia over the Internet and unsecured
channels of communications is putting pressure on scientists and engineers to develop …

This paper presents a solution for secure and efficient image encryption with the help of self-
adaptive permutation–diffusion and DNA random encoding. The plain image is firstly …

Four chaotic maps are used herein as case study to design an embedded cryptosystem
based on a pseudo-random number generator (PRNG). The randomness of the sequences …

This paper proposes a new block image encryption scheme based on hybrid chaotic maps
and dynamic random growth technique. Since cat map is periodic and can be easily cracked …

In this paper we propose a new image randomness measure using Shannon entropy over
local image blocks. The proposed local Shannon entropy measure overcomes several …

This paper aims to propose a novel no-equilibrium Hindmarsh–Rose (HR) neuron model
with memristive electromagnetic radiation effect. Compared with other memristor-based HR …

In recent years, a variety of chaos-based digital image encryption algorithms have been
suggested. Most of these algorithms implement permutations and diffusions at the pixel level …

Chaos-based stream ciphers form a prospective class of data encryption techniques.
Usually, in chaos-based encryption schemes, the pseudo-random generators based on …

An optical setup with a unique color image cryptography technique employing a chaotic
system is suggested in this study. For this purpose, deoxyribonucleic acid (DNA) encoding is …
