A new secure communication scheme is proposed based on chaotic synchronization.First a drive system and corresponding response system are built up respectively on the transmitting terminal and receiving terminal.The information signal is modulated on the transmitting terminal and turned it into chaotic transmitting signals,and then based Lyapurov stability theory; synchronization is introduced for the 2 chaotic systems.The chaotic signals are demodulated at the receiving terminal for the purpose of restorin...
