摘要
基于费马商和欧拉商构造的伪随机序列族具有良好的密码学性质.基于欧拉商确定了具有素数幂周期的r(r 为奇素数)元序列的定义对和离散傅里叶变换,得到了该序列的迹表示,这对序列的工程实现具有积极的意义.
Families of pseudorandom sequences derived from Fermat quotients and Euler quotients possess good cryptographic properties.In this paper,the definition pairs of r-ary sequences with prime power period and discrete Fourier transform are determined,which is based on Euler quotients.Then the trace representation of the sequences is obtained,which is of positive significance to the engineering implementation of the sequences.
