Analysis of Performance about Secure Communication Based on Fourth-Order Hyperchaotic System

摘要：

　　In this paper,we propose a new secure communication synchronization system which exploits the combination of the fourth-order hyperchaotic system and the synchronization theory.We study the fast encryption and decryption methods of the images and the performance analysis of the secure communication based on the hyperchaotic system.The simulation results show that the proposed hyperchaotic secure communication generates the unpredicted pseudorandom sequences which have greater complexity and better randomness characteristics comparing to the traditional chaotic encryption schemes.Furthermore,it has larger key space and higher safety performance.Since the proposed system provides a new thought for the synchronization problems of the hyperchaotic system,it is regarded as a potential scheme for resisting the popular attack means.
