| 摘 要： | 利用一维分段线性映射所具有的性质，提出了以周期性的参数扰动来控制基于一维分段线性映射的混沌滚动密钥发生器（RKG）的周期下界的方法，理论分析和仿真检验均证实，该方法所产生的混沌序列为均匀分布序列，二值密钥流序列为独立同分布序列，与m序列扰动的方法相比，该方法有较高的时效性和灵活性。

| Abstract: | Based on the special properties of one dimensional piecewise linear maps, this paper presented one method that the lower bound of the period of the running key generator based on one dimensional piecewise linear maps is controlled by adding periodical parameter disturbance. The theoretical analyses and simulations show that the generated chaotic sequences are uniformly distributed and the two valued key stream is independently and identically distributed. Compared with the method of adding m sequence disturbance to the output series, this method has better efficiency and flexibility. |
