Description
Summary:We presents an approach for secure communication by using combined discrete chaotic systems. Two well-known chaotic systems, Henon and Lorenz are combined as an illustrative example to demonstrate the effectiveness of the proposed approach. The chaotic systems adopt backstepping design an dead-beat synchronization scheme because of the characteristics that can reach to synchronization quickly. Simple chaotic masking technique is used in the simulation. The results as well as the theory analysis show that the proposed method is feasible and is of more security performance compared to the non-combined chaotic systems. The proposed scheme is not only can be carried out easily and easy to control, but also advances the security performance of whole system.
