In this paper, a new chaotic synchronization and secure communication method is proposed. In the transmitter, the modulation is realized by adding the information signal to a chaotic carrier, taking a modular operation on the sum, and embedding the result of the modular operation in the iteration of the chaotic dynamical system. In the receiver, the chaotic carrier is retrieved from the received signal by using a corresponding non dynamical system and then the information signal is recovered. The results of our study show that the chaotic synchronization method has the good immunity to interference and can be realized easily. It is also showed that the chaotic secure communication system is fine in security.
