基于钟控、缩减生成器的构造思想,结合个别元素控制扩大输出的方式构造了一种新型伪随机序列生成器—扩散输出生成器。分析得到其生成序列—扩散输出序列的周期、线性复杂度及游程分布。文中进一步改变扩散输出组,得到一组伪随机序列,分析得到相应序列的周期和线性复杂度,实现对扩散输出生成器的拓展. A novel pseudo-random sequence generator, diffuse output generator, is constructed based on the idea of ​​clock control and downscaling generator, combined with the control of individual elements to expand the output. The cycle, linear complexity and run length distribution of the generated sequence - diffusion output sequence are analyzed. In this paper, we further change the diffusion output group to get a set of pseudo-random sequence, and analyze the cycle and linear complexity of the corresponding sequence to achieve the expansion of the diffusion output generator.
