In this paper, we propose an image encryption algorithm based on four-dimensional chaotic
system to generate key and improve advanced encryption standard. The encryption …

The most interesting phenomenon in nonlinear dynamics and certainly one of the most
important changes in the understanding of the world in the last five or six decades, is the …

Decision making implies selection of the best decision from a set of possible options. In
some cases, this selection is based on past experience. Past experience is used to analyse …

This research paper explores the use of S-box and chaos theory in securing the
transmission of sensitive engineering blueprints. The study aims to demonstrate the …

This investigation presents an image encryption system and its security analysis, it is based
on cellular automata and a substitution box. The joint of these two techniques, allow to …

Steganography is defined as the art and science of writing hidden in such a way that no one

One of the oldest well-known algorithms that works on encrypting wireless communications
and that does not depend on large resources is the A5/1 algorithm and it is considered one …

Security is one of the main issues in Internet of Things (IoT). Encryption plays a curtail role in
making these systems secure. Substitution Box (S-Box) has an effective impact in block …
