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 novel approach for strong S-Box generation algorithm design based on chaotic scaled Zhongtang system

Çavuşoğlu, Ünal; Zengin, Ahmet; Pehlivan, İhsan; Kaçar, Sezgin (SPRINGER, 2017)

Substitution Box (S-Box) is one of the most significant structures used to create an encryption which is strong and resistant against attacks in block encryption algorithms. S-Box plays an important role in data encryption. ...
A Novel Hypogenetic Chaotic Jerk System: Modeling, Circuit Implementation, and Its Application

; Jiancheng Liu; Karthikeyan Rajagopal; Tengfei Lei; Kaçar, Sezgin; Arıcıoğlu, Burak; Çavuşoğlu, Ünal; Kökçam, Abdullah Hulusi; Anitha Karthikeyan (HINDAWI LTD, 2020)

When revising the polarity and amplitude information in the feedback, a unique hypogenetic jerk system was obtained which has two controllers to switch the equilibria between stable and unstable. After providing some basic ...
An exponential jerk system, its fractional-order form with dynamical analysis and engineering application

; Karthikeyan Rajagopal; Akgül, Akif; Sajad Jafari; Anitha Karthikeyan; Çavuşoğlu, Ünal; Kaçar, Sezgin (SPRINGER, 2020)

A simple jerk system with only one exponential nonlinearity is proposed and discussed. Dynamic analysis of the integer-order jerk system shows the existence of chaotic oscillations. A model for the fractional-order jerk ...
Crowd sensing aware disaster framework design with IoT technologies

Kerem Kucuk; Bayılmış, Cüneyt; Ahmet Furkan Sonmez; Kaçar, Sezgin (SPRINGER HEIDELBERG, 2020)

When a disaster occurs, a huge amount of inconsistent victim or damage information data is received by many different sources. Disaster management systems achieve the completion of a significantly vital task, which is to ...
New class of chaotic systems with equilibrium points like a three-leaved clover

Saleh Mobayen; Christos K. Volos; Kaçar, Sezgin; Çavuşoğlu, Ünal (SPRINGER, 2018)

This paper presents a new class of chaotic systems with infinite number of equilibrium points like a three-leaved clover. They signify an exciting class of dynamical systems which represent many major characteristics of ...
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 ...
