In this work, an efficient image encryption based on S-boxes and fractional-order logistic
map is proposed. The features of the fractional-order chaotic system in dynamical behaviors …

This paper proposes a finite time chaos synchronization approach for the secure
communication of satellite imaging. To this end, chaotic oscillators are considered in both …

Hundreds of image encryption schemes based on the conventional 2D image space exist in
the literature. Very few were built using the 3D image space. In this study, for better security …

With the increasing requirements of the performance in secure communication filed based
on chaos, chaotic systems have been gradually developed into higher dimensions. Because …

The quality of encryption is dependent on the complexity of the confusion-diffusion pattern
and the quality of the keystream employed. To enhance complexity and randomness, this …

In this paper, a five-dimensional discrete hyperchaotic map is constructed by combining
Logistic map and 3D discrete Lorenz map. Based on this chaotic system, a block-based …

Abstract The Internet of Things (IoT) has transformed the healthcare industry by enabling
new services and capabilities through connected devices and sensors. These devices, such …

Combining the metaverse and the Internet of Things (IoT) will lead to the development of
diverse, virtual, and more advanced networks in the future. The integration of IoT networks …

As a medium that can convey information vividly, the application of digital images is
increasingly widespread. Under various application environments, researchers are …

In this paper, a dynamic block image encryption using variable-length key and modified
Henon map is proposed. To surmount the defects of narrow chaotic range and frail chaotic …
