Abstract

A chaotic signal masking scheme involving the inverse system approach which uses nonautonomous chaotic systems is presented. In this context, two simple second-order nonautonomous systems are studied to demonstrate how such forced systems can be used for private communication purposes. The two main difficulties arising in such applications are the chaos synchronization and the exact duplication of the transmitter's nonlinear parts at the receiving end also. It is shown that our approach overcomes such difficulties by making use of second-order forced systems. Examples of circuit implementations for the transmitter and the receiver subsystems are discussed to investigate different recovering techniques.
