The synchrocontrol of a new chaotic system was studied. Based on Lyapunov stability theory, ada- pting control method and activated control method were used to realize the synchrocontrol when parameters were unknown. The smmm'y, reasoning and simulation experiments further prove the correctness of this conclusion. Finally, adaptive methods of chaotic synchronization were used to experimentalize secret commu- nication. The findings show that using chaotic masking can effectively restore the information signal.
