%X According to the basic definition and characteristics of several representatives of Chaotic Dynamical System, this paper promoted a broad sense explain about the existent reason for the invalid-keys and the quasi invalid-keys in Logistic-Map and soon, and the reason was the existence of k-period points in chaotic system. At the same time, the paper proposed several methods to resolve this problem. And the simulation results show that these methods have good efficiency and practicability.
