基于多重函数投影同步的保密通信新算法
|
Abstract:
本文提出了一种新的混沌同步方案——多重函数投影同步，该同步方案比许多现有同步方案更加广义，两个同步系统之间的同步行为更加复杂。基于所提的同步方案并引入参数扰动因子，设计了一种新的保密通信算法，并通过理论分析和数值模拟，证实了算法的有效性和可行性。最后，通过讨论和对比实验展示了该算法的安全性。
A generalized scheme of chaos synchronization, which is called multiple function projective synchronization, is first reported in this paper. This synchronization scheme is more generalized than many existing ones. Under the scheme, the synchronous behavior between two synchronized systems is more complicated. By utilizing the proposed synchronization scheme and introducing the parameter perturbation factor, a novel algorithm of secure communication is designed. From theoretical analysis and numerical simulations, the validity and feasibility of this algorithm is proved. Finally, some discussions and comparison experiments are established to illuminate the security of this algorithm.
