چکیده
This paper aims towards synchronization of Bhalekar-Gejji chaotic system and its application to secure communication. Synchronization is achieved using suitable nonlinear active control (NAC) scheme. Proposed synchronization is used to achieve secure communication using NAC. For secure communication, the information signal is masked with one of the state of chaotic system at transmitter end and retrieved at receiver end. Synchronization and convergence of error dynamics are achieved by using required Lyapunov stability condition. MATLAB simulation results validate synchronization of Bhalekar-Gejji chaotic system and its application to secure communication. Simulation results reveal that synchronization and its application using NAC is achieved successfully. Further, performance of NAC is given based on performance criteria terms as average synchronization error for both synchronization and its application to secure communication.

Anti-Synchronization of Complex Chaotic T-System Via Optimal Adaptive Sliding-Mode and Its Application In Secure Communication
In this paper, an optimal adaptive sliding mode controller is proposed for anti-synchronization of two identical hyperchaotic systems. We use hyperchaotic complex T-system for master and slave systems with unknown parameters in the slave system. To construct the optimal adaptive sliding mode controller, first a simple sliding surface is designed. Then, the optimal adaptive sliding mode controll...

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...
