Abstract
Abstract: In order to improve the security of confidential communication systems effectively, a combination-combination synchronization scheme based on finite time theory is proposed and applied to chaotic masked confidential communication. Four classical hyperchaotic systems with universal applicability are selected as the research objects. The backstepping method is used to design the combination-combination synchronous control scheme for different structural hyperchaotic systems based on finite-time theory and Lyapunov stability theory. The efficiency and strong robustness to external disturbances of the finite time control scheme are verified by numerical simulation and comparative experiments. The effectiveness of the controller and the strong robustness to external interference are verified by numerical simulation. A chaotic masking secure communication scheme is designed by using the finite time combination-combination synchronization. The simulation results show that the scheme can recover the original information signal quickly and effectively in the presence of external interference and channel noise, and has strong anti-decipherability.
