Abstract :
A secure communication method via chaotic parameter modulation is studied. Based on Lyapunov stability theory and active control strategy, the simple controller is presented. Via chaotic parameter modulation, chaotic secure communication is derived. The particle filtering technique is designed in the receiving terminal to make the information signals recover effectively. The simulation results show that chaos synchronization is effective, and the recovered signals are close to the information signals, moreover, it possesses strong confidentiality. Furthermore, the controller is simple and it is easy to implement in engineering.
