Secure Communication Based on a Hyperchaotic System with Disturbances

Abstract EN

This paper studies the problem on chaotic secure communication, and a new hyperchaotic system is included for the scheme design.

Based on Lyapunov method and H ∞ techniques, two kinds of chaotic secure communication schemes in the case that system disturbances exist are presented for the possible application in real engineering; corresponding theoretical derivations are also provided.

In the end, some typical numerical simulations are carried out to demonstrate the effectiveness of the proposed schemes.
