Abstract: In this paper, chau's circuit hyperchaotic systems with coupled-feedback are investigated and proved. Four pairs of double-scroll attractors have been produced by its hyprtchaotic dynamic behavior. The chaos masking of the hyperchaotic phenomena in the cryptography communications schemes and the application of chaos shift keying technology have been proposed and studied through numerical simulations

Key words: WTBZhyperchaos, double scroll attractor, secure communication
