Abstract
It is shown how a four-wing hyper-chaotic attractor can be used for secure communication using parameter convergence. Using some variables for complete replacement and some for feedback control and unknown parameter adaptation, two hyper-chaotic attractors are synchronized in a time less than the time scale of their chaotic oscillations. This synchronization is used for and secure communication of digital messages. The coding parameter of the transmitting system changes so rapidly that an intruder cannot infer any information about the attractors corresponding to the two coding parameters. The scheme presented in this paper is more secure as compared to other similar schemes. This is demonstrated by comparison with an existing scheme based on parameter adaptation and Lyapunov stability theory.
