Abstract

The problem of adaptive secure communication based on chaotic parameter modulation is discussed. Information signals are modulated to some parameter of the chaotic system in the master system, then, adaptive parameter identification and single controller is designed to structure an adaptive response system. Parameter estimation and chaos synchronization are achieved effectively. A nonlinear filter is applied to recover information signals from the receiver system effectively. Secure communication based on chaotic parameter modulation is guaranteed. Furthermore, the controller is simple and it is easy to implement in engineering. Simulation results show that chaos synchronization is effective, and the recovered signals are close to the information signals.
