Hyperchaos to Secure Communications According to Synchronization by a High Gain Observer

The purpose of this article is to secure the information message using a new six order continuous hyperchaotic system that we have developed. After studying and verifying the hyperchaotic behavior and stability of this system, a chaotic masking scheme is applied to secure the information between a transmitter and a receiver. The results of the simulations confirm the high performance of the observer designed for this high order system and the proposed method leads to an almost perfect restoration of the original signal.
