Control of chaos observer synchronization and the application in secure communication

Abstract

According to the principle of phase space reconstructing by the scale and its differential of a continuous time chaotic system, the synchronization of Lorenz system is investigated by employing chaos observer synchronization method. A theorem about chaos observer synchronization of Lorenz chaotic system is put forward based on the stability rule. Appling this method into secure communication, a new scheme of chaotic masking secure communication based on time division multiple is designed, and the performance of the communication system is analyzed. The results of Matlab simulation show that this scheme is effective.
