Blockchain-based IoT security solutions for IDS research centers
Hızal, Selman; Akhter, A.F.M. Suaib; Çavuşoğlu, Ünal; Akgün, Devrim (Elsevier B.V., 2024)The rapid evolution of the Internet of Things (IoT) has connected real-world objects to the Internet, enhancing digital interaction and introducing critical security vulnerabilities. Intrusion Detection Systems (IDS) are ... -
Chaos-based image encryption
Kaçar, Sezgin; Çavuşoğlu, Ünal; Jahanshahi, Hadi (Elsevier, 2024)Chaos-based encryption applications are at the forefront of engineering applications based on chaotic systems. When the studies in the literature are examined, it is seen that chaos-based image encryption applications are ... -
A Chaotic System with Infinite Equilibria and Its S-Box Constructing Application
Wang, Xiong; Akgül, Akif; Çavuşoğlu, Ünal; Viet-Thanh Pham; Duy Vo Hoang; Xuan Quynh Nguyen (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 ... -
An exponential jerk system, its fractional-order form with dynamical analysis and engineering application
Rajagopal, Karthikeyan; Akgül, Akif; Jafari, Sajad; Karthikeyan, Anitha; 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 ... -
An Exponential Jerk System: Circuit Realization, Fractional Order and Time Delayed Form with Dynamical Analysis and Its Engineering Application
Rajagopal, Karthikeyan; Akgül, Akif; Jafari, Sajad; Karthikeyan, Anitha; Çavuşoğlu, Ünal; Kaçar, Sezgin (World Scientific Publ Co Pte Ltd, 2019)Simple dynamical systems are of interest always. In this paper, we propose a simple jerk system with one exponential nonlinearity. Dynamical properties of the proposed system are investigated. To show the practical ... -
A Novel Cyber Security Model Using Deep Transfer Learning
Çavuşoğlu, Ünal; Akgun, Devrim; Hizal, Selman (Institute for Ionics, 2024)Preventing attackers from interrupting or totally stopping critical services in cloud systems is a vital and challenging task. Today, machine learning-based algorithms and models are widely used, especially for the intelligent ... -
A novel deep learning-based intrusion detection system for IoT DDoS security
Hizal, Selma; Çavuşoğlu, Ünal; Akgün, Devrim (Elsevier B.V., 2024)Intrusion detection systems (IDS) for IoT devices are critical for protecting against a wide range of possible attacks when dealing with Distributed Denial of Service (DDoS) attacks. These attacks have become a primary ... -
Performance Evaluation of Lightweight Encryption Algorithms for IoT-Based Applications
Panahi, Pejman; Bayılmış, Cüneyt; Çavuşoğlu, Ünal; Kaçar, Sezgin (Springer Heidelberg, 2021)Today, all smartphones, notebooks, or other communication devices could connect to the cloud, so the data are accessible everywhere. When these devices are interconnected through the internet, they make an Internet of ... -
S-Box Based Image Encryption Application Using a Chaotic System without Equilibrium
Wang, Xiong; Çavuşoğlu, Ünal; Kaçar, Sezgin; Akgül, Akif; Viet-Thanh Pham; Jafari, Sajad; Xuan Quynh Nguyen (Mdpi, 2019)Chaotic systems without equilibrium are of interest because they are the systems with hidden attractors. A nonequilibrium system with chaos is introduced in this work. Chaotic behavior of the system is verified by phase ... -
A Simple Chaotic Flow with Hyperbolic Sinusoidal Function and Its Application to Voice Encryption
Mobayen, Saleh; Volos, Christos; Çavuşoğlu, Ünal; Kaçar, Sezgin (Mdpi, 2020)In this article, a new chaotic system with hyperbolic sinusoidal function is introduced. This chaotic system provides a new category of chaotic flows which gives better perception of chaotic attractors. In the proposed ...
