This article creatively proposes a class of sorting matrices with fractal characteristics, named
the fractal sorting matrix (FSM), and introduces its iterative calculation method. The FSM is …

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 (IE) has been essential for internet-based storing and transferring in recent
years. Effective chaotic systems play a crucial role in IE schemes which widely depend on …

This paper proposes a secure and energy-efficient Internet of Things (IoT) model for e-
health. The main objective is to secure the transmission and retrieval of biomedical images …

To ensure security, image encryption algorithms generally include two stages: permutation
and diffusion. The traditional image permutation algorithms include the sort-based …

Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

Image encryption is a straightforward strategy to protect digital images by transforming
images into unrecognized ones. The chaos theory is a widely used technology for image …

In view of the problem that dissipative chaos has attractors and is easy to be attacked by
reconstruction, which leads to the security defects of encryption algorithm based on …

With complex properties of ergodicity, unpredictability and sensitivity to initial states, chaotic
systems are widely used in cryptography. This paper proposes a two-dimensional Logistic …

In this paper, a new two-dimensional Logistic ICMIC cascade map (2D-LICM) is proposed
based on cascade modulation couple (CMC) model. Performance evaluations show that it …
