摘要:
基于Lyapunov稳定性理论,设计一种含有指数函数的非线性同步控制器,实现了异构磁控忆阻混沌系统之间的完全同步、比例投影同步和函数投影同步. 通过误差曲线、同步时序图及同步相图等证明同步控制器的有效性与可行性. 选择合适的密钥,实现异构忆阻系统同步在彩色图像加密中的应用,通过直方图、相关性及密钥敏感性分析验证了加密效果. 结果表明,将这种忆阻混沌同步应用到图像加密中具有很高的研究价值与工程意义.
Abstract:
This paper,based on Lyapunov stability theory,designs the nonlinear synchronization controller with exponential function,which is used to realize complete synchronization,proportional projective synchronization and function projective synchronization between two heterogeneous memristor-based chaotic systems. Subsequently,the validity and feasibility of the synchronization controller are proved by the error curve,the synchronous sequence diagrams and synchronous phase. Moreover,the application of the synchronization in color image encryption is fulfilled by selecting appropriate keys. Correspondingly,the effect of encryption is verified by the analysis of histogram,correlation and key sensitivity. Finally,it is found that the application of the synchronization of memristive systems in image encryption is meaningful and valuable through memerical results.
