Synchronizing chaos by driving of discrete chaotic signal

In this paper, the method of synchronizing chaos by driving of discrete cha otic system in continuous chaotic systems is proposed. The logistic map, He non map and the system of Lorenz are tak en as three typical examples. The simulation results show that two continuous chaotic systems can be synchron ized completely when the strength of the driving signal is large enough and the spectrum of the output signal is similar to the spectrum of white nois e. At the sametime, we have studied the possibility of secrete communicatio n based on the method proposed in this paper.
