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 …

Recently, a number of chaos-based image encryption algorithms that use low-dimensional
chaotic map and permutation-diffusion architecture have been proposed. However, low …

We propose a new image encryption algorithm based on the spatiotemporal chaos of the
mixed linear–nonlinear coupled map lattices. This spatiotemporal chaotic system has more …

This paper proposes a novel confusion and diffusion method for image encryption. One
innovation is to confuse the pixels by transforming the nucleotide into its base pair for …

We propose a new image encryption algorithm which is based on the spatiotemporal non-
adjacent coupled map lattices. The system of non-adjacent coupled map lattices has more …

A novel image encryption scheme employing the memristive hyperchaotic system, cellular
automata (CA) and DNA sequence operations is presented, which consists of diffusion …

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 …

This paper proposes a bit-level permutation and high-dimension chaotic map to encrypt
color image. Firstly, convert the plain color image of size (M× N) into a grayscale image of …

In recent years, various image encryption algorithms based on the permutation–diffusion
architecture have been proposed where, however, permutation and diffusion are considered …

This paper proposes a novel image encryption scheme based on the improved hyperchaotic
sequences. Firstly, the hyperchaotic sequences are modified to generate chaotic key stream …
