摘    要:提出了利用离散混沌系统联合加密来实现保密通信的方法。引用著名的Henon和Lorenz混沌系统作为仿真实验证明了其可行性,混沌系统均采用backstepping和dead-beat同步设计方案,以快速达到同步,理论分析证明,此种方法不仅是可行的,且与非联合混沌系数相比,加强了保密性。混沌屏蔽技术仿真结果也证明,该系统不仅实现简单,容易控制,而且增强了整个系统的保密性能。

关 键 词:联合离散混沌系统  保密通信  Backstepping设计  Dead-beat同步  混沌屏蔽

Abstract: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.
Keywords:Combined discrete chaotic system  Secure communication  Backstepping design  Dead beat synchronization  Chaotic masking
