【Abstract】 The realization of chaos secure communication based on the method of interval synchronization recalling memory is provided. It sends a binary sequence when sending modulated signal by the transmitter. By forced synchronization and freely evolving synchronization, synchronization is maintained between transmitter and receiver system. At the same time, by the receiving binary sequence the speech signal can be recovered wholly and exactly. Finally, computer simulation of modified Logistic chaotic system is given, and the results prove that the method is valid.更多还原
