In many cases, images contain sensitive information and patterns that require secure
processing to avoid risk. It can be accessed by unauthorized users who can illegally exploit …

A novel color image encryption algorithm is proposed in this paper which utilizes SHA-256
hash function to modify the initial conditions and control parameters of chaotic system. Three …

This paper combines DNA computing with double-chaos systems and proposes an
algorithm for color image encryption at the bit level. First, we use Arnold algorithm to …

Image encryption is a useful solution to achieve confidentiality while transmitting digital
images over unsecure public networks. Among recently proposed encryption schemes, a …

In the past, many image encryption schemes have been developed through the swapping
operations at the different levels of granularity. These levels span bits, Deoxyribonucleic …

Based on deoxyribonucleic acid (DNA for short) sequence exclusive OR (XOR for short)
operation and real and complex chaotic systems, a new improvement color image …

In the past decade, image encryption has emerged as a matter of interest to scientists and
researchers. The paper presents a synchronous permutation-diffusion image encryption …

Hundreds of image encryption algorithms have been developed for the security and integrity
of images through the combination of DNA computing and chaotic maps. This combination …

The secure key generation is the predominant requirement of an image encryption. Chaotic
maps are often considered by the researchers for secure key generation. However, chaotic …

Stability and complexity of the encryption process besides affordable encryption time are the
two challenges of image encryption. In this paper, Chen chaotic system is applied to …
