Digital secure communication scheme based on multi-scroll chaotic systems

In order to enhance the anti-jamming ability and to obtain high secrecy of the traditional chaotic communication system, a scheme of digital chaotic secure communication based on the synchronization of multi-scroll chaotic systems was presented. The character of the chaotic system was used to construct chaotic keys in the scheme of communication. Numerical results show that the secure communication system is highly secure against the error function attack, and there is some ability against noise when the synchronization signal is disturbed by noise.
