Data Study on the Chaotic Synchronization Driven by External Chaotic Signal
The principle of the chaotic synchronization driven by external chaotic signal instead of noise signal is stated briefly. After comparing the intermittent driving method with the continuous driving method, we find that the synchronized effect of the previous is relative to the sampling period and the driving strength coefficient, and we should choose the two parameters reasonably. Then apply the chaotic synchronization driven by discrete chaotic signal to secure communication, the experiment shows that the system is robust and its keys are resourceful, so the scheme is of high security.
