Secure Communication and Implementation for a Chaotic Autonomous System

Abstract

In this paper, a three-dimensional chaotic autonomous system is presented. The stability of the equilibrium and the conditions of the Hopf bifurcation are studied by means of nonlinear dynamics theory. Then, the circuit of chaotic system is structured out in Multisim platform by the unit circuit. The chaotic system is applied to secure communications by linear feedback synchronization control. All simulations results performed on three-dimensional chaotic autonomous system are verified the applicable of secure communication. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.400
