An adaptive chaos synchronization scheme applied to secure communication
نویسنده
چکیده
This paper deals with the problem of synchronization of a class of continuous-time chaotic systems using the driveresponse concept. An adaptive observer-based response system is designed to synchronize with a given chaotic drive system whose dynamical model is subjected to unknown parameters. Using the Lyapunov stability theory an adaptation law is derived to estimate the unknown parameters. We show that synchronization is achieved asymptotically. The approach is next applied to chaos-based secure communication. To demonstrate the efficiency of the proposed scheme numerical simulations are presented. 2003 Elsevier Science Ltd.

متن کاملModified Sliding-Mode Control Method for Synchronization a Class of Chaotic Fractional-Order Systems with Application in Encryption
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 ...

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...

متن کاملA Control Perspective on Communication Using Chaotic Systems 1
Secure communication using chaotic systems is considered from a control point of view. It is shown that a synchronization-based scheme for secure communication described in the literature may in fact be interpreted as an adaptive identiication scheme. Two examples where the existing scheme fails to achieve the reconstruction of an encoded message are treated using adaptive identiication techniq...
