小周期

To begin with, theory of FCSR and its sequence is summarized and investigated. Furthermore, emphasis is placed on the vaule of 2-adic complexity. A conclusion is drawn that the vaule lies in the relation between 2-adic complexity and lineai complexity of a same seqence. Fact that there exists sequence with high linear complexity but low 2-adic complexity is given and analyzed. The value of 2-adic complexity in cryptanalysis can be directly drawn from the very fact. A series of problems are opened based on the value and discussions are done in various depth. Some good results are obtained in these problems such as the 2-adic complexity distribution of periodic sequences and the stability of 2-adic complexity. The value of FCSR in stream cipher design is discussed at the same time.

首先对FCSR及其序列理论进行了系统的总结和研究，然后重点探讨了2-adic复杂度的流密码意义，通过论证表明，存在线性复杂度较大而2-adic复杂度较小的序列类，从而明确了2-adic复杂度的流密码分析意义，进而提出了一系列相关的研究问题并进行了不同深度的探讨，对其中周期序列的2-adic复杂度分布和2-adic复杂度的稳定性等问题得到了较好的结果；同时对FCSR的流密码设计意义进行了探讨，对其中的问题给出了一些思路或简单结论。
