摘　　要：提出了一种时变参数混沌同步保密通信方法,极大地提高了混沌同步的通信保密性,使目前的各种破译手段均无法破译该方法;并基于Chua电路进行了仿真。采用该方法进行混沌同步通信,击败了目前各种破译手段的攻击,证实了其高保密性。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.
