摘 要: 论文将自扩生成器与缩减生成器组合构成了一种新型的伪随机序列生成器——缩扩生成器,它由两个三元的线性反馈移位寄存器(LFSR)构成。文中讨论了某种特殊情形下得到的缩扩序列的周期、符号分布、特征多项式等密码学性质。 This paper proposes a new pseudo-random sequence generator, which is a combined model of the selfextended generator and the shrinking generator, called a SE-generator in short. It is constructed by using two ternary linear feedback shift registers(LFSR). The period, symbol distribution and characteristic polynomial of the SE-sequence are also discussed.
