摘要
构造了两类一元单圈T-函数,这两类T-函数在软件实现上速度快、效率高,而且所生成的序列线性复杂度高、稳定性强。此外,还研究了参数与单圈T-函数的关系,给出了一个由已有的一元单圈T-函数和一个偶参数来构造新的一元单圈T-函数的方法。
Two classes of single cycle T-functions on single-word were presented, which could be efficiently implemented in software environment and produce sequences with high linear complexity and being stable. Moreover, based on the research on the relationship between parameters and single cycle T-functions, a method to construct new single cycle T-functions from known single cycle T-functions and even parameters was given.
