A Chaotic System with Infinite Equilibria and Its S-Box Constructing Application

Xiong Wang; Akif; Çavuşoğlu, Ünal (MDPI, 2018)

Systems with many equilibrium points have attracted considerable interest recently. A chaotic system with a line equilibrium has been studied in this work. The system has infinite equilibria and exhibits coexisting chaotic ...
A new 4-D chaotic hyperjerk system, its synchronization, circuit design and applications in RNG, image encryption and chaos-based steganography

S. Vaidyanathan; Akgül, Akif; Kaçar, Sezgin; Çavuşoğlu, Ünal (SPRINGER HEIDELBERG, 2018)

Hyperjerk systems have received significant interest in the literature because of their simple structure and complex dynamical properties. This work presents a new chaotic hyperjerk system having two exponential nonlinearities. ...
A New Chaotic System with Multiple Attractors: Dynamic Analysis, Circuit Realization and S-Box Design

Qiang Lai; Akif Akgul; Chunbiao Li; Guanghui Xu; Çavuşoğlu, Ünal (MDPI AG, 2018)

This paper reports about a novel three-dimensional chaotic system with three nonlinearities. The system has one stable equilibrium, two stable equilibria and one saddle node, two saddle foci and one saddle node for different ...
Determination of the Gas Density in Binary Gas Mixtures Using Multivariate Data Analysis

Adak, Muhammed Fatih; Akpınar, Mustafa; Yumuşak, Nejat (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

Some solvents in commercial products may have harmful effects on human health. It is important to determine the percentage of this certain solvent in a product to detect any possible health hazards. In this paper, three ...
Secure image encryption algorithm design using a novel chaos based S-Box

Çavuşoğlu, Ünal; Kaçar, Sezgin; Pehlivan, İhsan; Zengin, Ahmet (PERGAMON-ELSEVIER SCIENCE LTD, 2017)

In this study, an encryption algorithm that uses chaos based S-BOX is developed for secure and speed image encryption. First of all, a new chaotic system is developed for creating S-Box and image encryption algorithm. Chaos ...
The design and implementation of hybrid RSA algorithm using a novel chaos based RNG

Çavuşoğlu, Ünal; Akgül, Akif; Zengin, Ahmet; Pehlivan, İhsan (PERGAMON-ELSEVIER SCIENCE LTD, 2017)

The number of attempts to break modern encryption methods increases day by day and therefore the need for the design of systems to ensure higher security has occurred. This study aims, an encryption algorithm that combines ...
