Chaos-based cryptology has become one of the most common design techniques to design
new encryption algorithms in the last two decades. However, many proposals have been …

In this paper, we introduce a novel color image encryption algorithm based on DNA
sequence operations, one-time keys and the spatiotemporal chaos. Firstly, the key streams …

In the paper, a novel image encryption algorithm based on DNA sequence operations and
chaotic systems is proposed. The encryption architecture of permutation and diffusion is …

Because a DNA nucleotide sequence has the characteristics of large storage capacity, high
parallelism, and low energy consumption, DNA cryptography is favored by information …

There are two shortcomings existing in the current color image encryption. One is that high
correlation between R, G, B components of the original image may be neglected, the other is …

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 order to improve the problems of small key space and poor security when the one-
dimension logistic chaotic map is applied in image encryption, we propose a modified …

In order to overcome the difficulty of key management in “one time pad” encryption schemes
and also resist the attack of chosen plaintext, a new image encryption algorithm based on …

A new quantum image encryption scheme is suggested by using the iterative generalized
Arnold transforms and the quantum image cycle shift operations. The times of the quantum …

Based on deoxyribonucleic acid (DNA) coding and two excellent low-dimensional chaotic
systems, a new color image cryptosystem is proposed in this paper. The presented image …
