 This paper discusses the periodicity of feedforward sequences.Ageneral method to get the longest period of feedforward sequences is putforward. 本文讨论了前馈序列的周期性问题,找到了使前馈序列获得最大周期的一般方法。 The problem,how to choose the set of phase vectors of tap sequences in the nonlinear feedforward generator such that some frequency component of the feedforward sequence under Galois-Field Fourier transform is equal to zero, will be discussed in this article. We will give the solution of the problem's existence, enumeration and construction by PFZ Algorithm when the number n of the LFSR's stages and the number m of variables of the feedforward function are coprime, and prove PFZ Algorithm is efficient... The problem,how to choose the set of phase vectors of tap sequences in the nonlinear feedforward generator such that some frequency component of the feedforward sequence under Galois-Field Fourier transform is equal to zero, will be discussed in this article. We will give the solution of the problem's existence, enumeration and construction by PFZ Algorithm when the number n of the LFSR's stages and the number m of variables of the feedforward function are coprime, and prove PFZ Algorithm is efficient when n or m is small. 本文讨论对于前馈网络,如何选取抽头序列的相位向量集,使得前馈序列在Galois域Fourier变换下某一频率分量为零(即前馈序列的线性复杂度退化)。当LFSR的级数n和前馈函数的变元个数m互素时,本文由PFZ算法给出了上述问题的存在性、计数和构造性组合问题的完整解,且证明了当n或m较小时,PFZ算法是一个有效的算法。 Bit security is one of the important indexes on measuring stream ciphers.This paper discusses the security of stream ciphers by treating them as systems with memory.The models studied in this paper include linear shift register sequences,feedforward sequences and clock controlled sequences.The results may be helpful for some new realization of the local security of stream cipher systems. 流密码的比特安全性是衡量密码体制好坏的重要指标。本文把流密码看作一个有记忆系统对其比特安全性进行了讨论。本文研究的模型包括线性移位寄存器序列，前馈序列和钟控序列。通过研究它们的比特安全性，可以对这些流密码体制在局部范围的安全程度有新的认识。 << 更多相关文摘
