This paper studies the adaptive synchronization of a switching system with unknown parameters which switches between Rössler and unified chaotic system. Using Lyapunov stability theory control method, receiver will achieve drive would be estimated by receiver. Then proposed is used for secure communications based on communication schemes including masking, modulation, shift key strategies. Since two systems are almost unknown, it more difficult intruder to extract useful message from transmission channel. In addition, new in signal mask (or modulate) transmitted components also presented. Finally, some simulation results given show effectiveness schemes.
