| Abstract: | A chaotic synchronized secure communication method based on time-varying parameters is presented. The method improves communication secure performance greatly and can defeat all known attacking methods at the present time. The parameter sensitivity of chaotic synchronization systems makes chaotic synchronization robust, but eavesdroppers can follow this way to attack and defeat communication systems. The time-varying parameters method can solve this problem. Based on Chua circuit, the simulations show that this method have defeated the attacks of all known breaking methods at present, such as generalized synchronization, adaptive parameter estimation, and so on. |
