摘　　要：从混沌动力系统的基本定义和性质出发,给出了Logistic等典型混沌动力系统中周期k周期点的存在将导致周期k"密钥"和"拟平凡密钥"现象存在的广义解释;同时提出了几种克服该现象的实用解决方案。实验结果证明这些方案实时有效,实用性强。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.
