A robust APD synchronization scheme and its application to secure communication

This paper proposes a robust active–passive decomposition (APD) synchronization scheme. Compared with the original APD scheme, the robust APD scheme can effectively deal with the uncertainty in the master. Further, this scheme can also be applied to secure communication, where the hidden message can be recovered by the concept of equivalent control. Simulation results of Lorenz system verify the effectiveness of the proposed scheme.
