摘要

A new scheme of chaotic secure communication based on active-passive synchronization is proposed. Not only the complexity of system is reduced, but also the capability is enhanced. At the same time, it does not destroy the correlation. The experimental results show that the proposed method can recover signals well. Because the system is very sensitive to the parameters, which reaches the level of asynchronous method, and it can resist the attack of decryption methods to chaotic synchronization, the scheme is safe.
