%X The security of several typical chaotic synchronized secure communication schemes , as well as the respective unmasking methods are studied to find the way to improve the security. A new secure communication scheme based on active-passive decomposition using parameters perturbation technique, which makes it has a kind of dynamic secrete key, is analyzed in this paper. The dynamic secrete key contributes to the capacity against the unmasking methods. Computer simulation and security test results demonstrate that the scheme is high in security and good in synchronization properties , and that it is safe to the attack of the unmasking methods mentioned in this paper.
