一类平衡前馈序列的构造与性质

Construction and Properties of Balance Feedforword Sequences

该文采用m序列选控传统前馈密码系统的方法,在继承了Bent函数谱值均匀优点的同时,使得产生的序列具有理想的平衡性、大的周期和高的线性复杂度,且能抵抗现有的线性逼近攻击和相关攻击.

By using an m-sequence controlling a traditional feedforward stream cipher, this paper constructs a new feedforward network whose sequences have ideal balance, large period and linear complexity, it can also resist on linear approaching attack and correlation attack, at the same time it inherits the virtues of Bent functions's even Walsh spectra.
