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 …

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

In recent years, a number of image encryption algorithms based on the permutation–
diffusion structure have been proposed. However, the control parameters used in the …

In this paper, an image encryption system is proposed that uses only addition operation to
achieve higher efficiency at diffusion phase after DNA encoding at pixel level. The image is …

This paper proposes a new one-time pad scheme for chaotic image encryption that is based
on the multiple mixed hash functions and the cyclic-shift function. The initial value is …

A new block cipher for gray images is proposed in this paper which fully utilizes whole set of
DNA complementary rules dynamically for encoding and decoding each pixel of a block …

In this manuscript, an image encryption based on dynamic S-boxes is presented, in which
the S-boxes are constructed by chaotic systems. An external 256-bit key and the last pixel of …
