摘要
本文首先给出了布尔函数是m阶相关免疫的充要条件,其次介绍了一种从两个n个变元的m阶相关免疫函数构造n+1个变元的m+1阶相关免疫函数的方法。
In this paper,we first give a sufficient and necessary condition for the boolean functions to be mth-order correlation-immune. Secondly, we discuss a way that construct a (m+1) th-order correlation-immune function with n+1 binary random variables using two ruth-order correlation-immune functions with n binary random variables.
