Due to the extensive demand for digital images across all fields, the security of multimedia
data over insecure networks is a challenging task. The majority of the existing modern …

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 …

Image encryption schemes can be vulnerable to a variety of cryptanalysis attacks. The use of
key-dependent dynamic S-boxes has been shown to improve security. Threats of chosen …

Currently, embedded systems can be found everywhere in quotidian life. In the development
of embedded systems, information security is one of the important factors. Encryption is an …

In the present era of digital communication, secure data transfer is a challenging task in the
case of open networks. Low-key-strength encryption techniques incur enormous security …

In this paper, we present a 2D Logistic-Sine-Cosine map (2D-LSCM) which is based on the
classical 2D Logistic, Sine and Cosine maps. Performance analysis shows that it has larger …

Chaotic-based S-box image encryption schemes promise to be a practical solution for
securing digital images. However, the high-dimensional continuous chaotic has increased …

A novel image encryption algorithm based on nonlinear discrete chaotic umbrella map and
Yang-Gu mixture amplitude-phase retrieval algorithm in fractional Fourier domain is …

Securing digital images against modern attacks is a hot research topic in the field of
cryptography. Several encryption schemes have been proposed, but either they do not …

In the existing literature, numerous chaos-based multimedia encryption schemes have been
presented. Benefiting from inherent properties such as ergodicity and key-sensitivity; this …
