With quaternion theory, the traditional discrete fractional Tchebyshev transform is extended
to the quaternion algebra domain for multi-image processing. A new multi-image encryption …

Image encryption is an essential method for ensuring confidentiality during transmission on
open channels. Digital images have a high correlation with large redundant data, requiring …

This paper proposes a video security transmission enhancement algorithm based on block
permutation and dynamic multiplexing sequences encryption based on 4D autonomous …

Drone-based surveillance has become widespread due to its flexibility and ability to access
hazardous areas, particularly in industrial complexes. As digital camera capabilities …

In 2019, a chaotic image encryption scheme based on a variant of the Hill cipher (VHC-
CIES) was proposed by the Moroccan scholars. VHC-CIES introduces a Hill cipher variant …

Over the past few years, there has been a rise in the utilization of chaotic encryption
algorithms for securing images. The majority of chaos-based encryption algorithms adhere …

Protecting digital data, especially digital images, from unauthorized access and malicious
activities is crucial in today's digital era. This paper introduces a novel approach to enhance …

Recently, an image encryption scheme based on a 2D hyperchaotic map is proposed. It
adopts the permutation–diffusion architecture and consists of three steps, which are …

The non-linear property of Chaos is a promising approach to information security, and many
accomplishments have been made by combining Chaos with several sub-security domains …

This study creatively introduces a class of adaptive Fourier decomposition (AFD) techniques
into the field of image encryption, where AFD and its variants are newly developed signal …
