Abstract

A system for hyper-chaos secure communication, for conveying data confidentially from a transmitter to a receiver, includes: (1) a hyper-chaotic signal generator, for carrying a message into a first signal of the hyper-chaotic signal generator; (2) a transmitter'"'"'s adjusting parameter device, for adjusting a first inner coupling parameter of the hyper-chaotic signal generator, causing the hyper-chaotic signal generator transforming the message and the first signal into a hyper-chaotic message; (3) a hyper-chaotic synchronization receiver, for adjusting a second inner coupling parameter of the hyper-chaotic synchronization receiver via a receiver'"'"'s adjusting parameter device, causing the hyper-chaotic synchronization receiver generating a second signal to realize simplex-coupling asymptotical synchronization with the first signal after the receiver receiving the hyper-chaotic message; and (4) a recovery device, for obtaining a difference between the hyper-chaotic message and the second signal, inputting the difference and translating the message via a recovery setting of the recovery device.
