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 …

An image encryption algorithm based on chaotic system and deoxyribonucleic acid (DNA)
sequence operations is proposed in this paper. First, the plain image is encoded into a DNA …

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 …

Currently, color image encryption is important to ensure its confidentiality during its
transmission on insecure networks or its storage. The fact that chaotic properties are related …

We designed a stream-cipher algorithm based on one-time keys and robust chaotic maps, in
order to get high security and improve the dynamical degradation. We utilized the piecewise …

Chaos-based encryption appeared recently in the early 1990s as an original application of
nonlinear dynamics in the chaotic regime. In this paper, an implementation of digital image …

A new method for obtaining strong S-boxes based on chaotic map and Teaching–Learning-
Based Optimization (TLBO) is presented in this paper. Our method presents eight rounds; …

In this paper, a novel image encryption scheme is proposed based on reversible cellular
automata (RCA) combining chaos. In this algorithm, an intertwining logistic map with …

Based on hyper-chaotic systems, a novel image encryption algorithm is introduced in this
paper. The advantages of our proposed approach are that it can be realized easily in one …

Two pseudorandom binary sequence generators, based on logistic chaotic maps intended
for stream cipher applications, are proposed. The first is based on a single one-dimensional …
