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 …

This paper summarizes the symmetric image encryption results of 27 different algorithms,
which include substitution-only, permutation-only or both phases. The cores of these …

In this paper, a novel triple-image encryption and hiding algorithm is proposed by combining
a 2D chaotic system, compressive sensing (CS) and the 3D discrete cosine transform (DCT) …

In this paper, we propose a novel image encryption scheme based on DNA
(Deoxyribonucleic acid) sequence operations and chaotic system. Firstly, we perform bitwise …

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 …

In recent years, a variety of effective chaos-based image cryptosystems have been
proposed. One of the architectures of this kind of cryptosystems is composed of multiple …

In this paper, we propose a new loss-less symmetric image cipher based on the widely used
substitution–diffusion architecture which utilizes chaotic standard and logistic maps. It is …

Confidentiality is an important issue when digital images are transmitted over public
networks, and encryption is the most useful technique employed for this purpose. Image …
