Chua’s chaotic synchronized system and its main properties are investigated and a multistage chaotic synchronized system for secure communication is proposed. It is shown that the message signal hidden in chaotic drier of the system can be perfectly reconstructed

and the bandwidth

the characteristic of distortion

and the level of security are improved. Examples of speech and still image communication are presented by using the system. level of security are improved.Examples of speech and still image communication are presented by using the system.
