Image encryption is gaining popularity due to the rapid use of internet technology. Security
attacks on the image can occur when images are shared through the internet. E-governance …

Confidentiality of images during data communication is a prime concern of many
researchers, as a result, several mechanisms have been proposed for image encryption. An …

Chaotic-maps-based image encryption methods have been a topic of research interest for a
decade. However, most of the proposed methods suffer from slow encryption time or …

Internet is used as the main source of communication throughout the world. However due to
public nature of internet data are always exposed to different types of attacks. To address …

World has become a global village after introduction of social media and social networks.

To improve the abilities of image encryption systems to resist plaintext attacks and
differential attacks, a novel plaintext-related image encryption scheme based on Josephus …

Chaotic systems are widely used in various fields, but under the finite precision device,
chaotic systems would fall into a cycle and subsequently the performance degrade. Thus …

Recently, the field of lightweight cryptography (LWC) has emerged in response to the
security needs of low-cost, widely used technology. It is essential to implement an encryption …

In these days of technology, the usage of images has become increasingly high especially
now that almost everyone has access to internet. Also, image helps us to learn, grabs our …
