摘要
给出了Galois环上弹性函数的一种构造方法:通过拟仿射函数组合若干弹性函数得到更高弹性阶的弹性函数。讨论了拟仿射函数的构造。
Presents a method to combine resilient functions over a Galois ring by a quasi affine function to get a new resilient function of higher resilient order. From the discussion of the construction of quasi affine functions, it is seen that there are abundant choices of quasi affine functions.
