This paper proposes a digital network communication scheme based on spatio-temporal chaos synchronization, and realizes two-way real-time voice communication by using software.In this scheme, two unidirectional coupling mapping lattice (OCOML) systems of receiving and sending ends are identified by the same chaotic signal And its spatiotemporal chaos output signals are respectively used as the key sequence for encryption and decryption.The coupling parameter of OCOML is the master key of the system.The main advantage of the system is that the transmission efficiency is high and the real-time communication is facilitated by software, and The security of communications has been improved.
