Time-Varying Parameter Method with High Security Performance for Chaotic Synchronized Communication

A chaotic synchronized secure communication method based on time-varying parameter is presented. The method improves security performance of communication greatly, and can defeat all kinds of attacking methods at present. The parameter sensitivity of chaotic synchronization makes chaotic synchronization robust, but eavesdroppers can follow this way to attack and defeat communication system. Time-varying parameter method can solve this problem. In simulations, based on Chua circuit to communicate, the time-varying parameter method defeated the attacking of all kinds of breaking methods at present. The high security performance of this method is confirmed by these simulations
