Nonlinear Sprott94 Case A chaotic equation Synchronization and masking communication applications

Uyaroğlu, Yılmaz; Pehlivan, İhsan (PERGAMON-ELSEVIER SCIENCE LTD, 2010)

The nonlinear autonomous Sprott94 Case A chaotic equations are algebraically simple but can generate a complex chaotic attractor In this paper the Sprott94 Case A system is found suitable for chaotic synchronization circuits ...
Real Time Hardware Implementation of the 3D Chaotic Oscillator which having Golden-Section Equilibra

Tuna, Murat; Can Bulent Fidan; Ismail Koyuncu; Pehlivan, İhsan (IEEE, 2016)

In this study, the continuous-time, autonomous, 3D chaotic system having golden-section equilibra which is recently presented in the literature is implemented firstly as discrete time on an FPGA. In this design, the 3D ...
Real-time high-speed 5-D hyperchaotic Lorenz system on FPGA

Ismail Koyuncu; Murat Alcin; Tuna, Murat; Pehlivan, İhsan; Varan, Metin; Sundarapandian Vaidyanathan (INDERSCIENCE ENTERPRISES LTD, 2019)

Chaotic systems have several engineering applications such as cryptology, random number generators, image processing and secure communication. A basic structure used in these studies is a chaotic oscillator design that ...
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 ...
Signal Processing and Communications Applications Conference

Tuna, Murat; Ismail Koyuncu; Can Bulent Fidan; Pehlivan, İhsan (IEEE, 2015)

Simplified chaotic diffusionless Lorentz attractor and its application to secure communication systems

Pehlivan, İhsan; Uyaroğlu, Yılmaz (INST ENGINEERING TECHNOLOGY-IET, 2007)

Diffusionless Lorentz equations a simplified one-parameter version of the well-known Lorentz model. Also, it was attained in the limit of high Rayleigh and Prandtl numbers, physically corresponding to diffusionless convection. ...
SIMULATION AND CIRCUIT IMPLEMENTATION OF SPROTT CASE H CHAOTIC SYSTEM AND ITS SYNCHRONIZATION APPLICATION FOR SECURE COMMUNICATION SYSTEMS

Uyaroğlu, Yılmaz; Pehlivan, İhsan (WORLD SCIENTIFIC PUBL CO PTE LTD, 2013)

Nowadays, many simulations, implementations, synchronization and secure communication applications of chaotic circuits have been introduced in literature. However, electronics circuit design and implementation of nonlinear ...
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 ...
