A method of realizing secure communication by using discrete chaotic system combined encryption is proposed. The famous Henon and Lorenz chaos system is cited as a simulation experiment to prove its feasibility. The chaotic system adopts the synchronous design scheme of backstepping and deadbeat to achieve the synchronization quickly. Theoretical analysis proves that this method is not only feasible, but also enhances confidentiality compared with non-joint chaotic systems. The simulation result of chaos shielding technology also proves that this system not only realizes simple and easy control, but also enhances the confidentiality of the whole system.
