Wireless Secure Communication Systems Design Based on Chaotic Synchronization

In order to solve security of data transmission in wireless network, a secure communication method based on chaotic synchronization is presented. By designing nonlinear state observer, two chaotic systems are constructed and kept synchronized, realizing the complete recovery of the encrypted signal; the stability of the synchronized system is being analyzed at the same time. Simulation results show that the proposed scheme has the characteristics of simple design, fast synchronized speed and high security when a well-known Rossler chaotic system is applied to secure communication.
