A chaos scheme for secure communication based on neural network

This paper presents a method for using chaos in the digital domain for secure communications. The method uses a well-trained multilayer neural network to generate the chaotic sequence whose randomness is excellent. The corresponding secure communication approach is also proposed. In the transmitter, the modulation is realized by adding the information signal to this chaotic sequence generated by neural network. In the receiver, the chaotic carrier is retrieved from the received signal by using an equivalent neural network, and then the information signal is recovered. The anti-decipher ability of this method is also analyzed. The computer experiments show that this method has the good immunity to interference and can be realized easily, and the chaotic secure communication system based on neural network is fine in security
