多输出函数的一些密码学性质

Some Cryptographic properties of Multi-output Functions

首先对处理布尔函数的Ｗａｌｓｈ变换进行了修改，使其能应用于多输出函数ｆ（ｘ）：ＧＦ，（１≤ｍ≤ｎ）；其次对多输出函数的退化性、线性结构、非线性性和相关免疫性等密码学性质进行了讨论。

Firstly,the walsh transform that deal with Boolean functions is modified in order to deal with multi-out -put function f(x):(1≤m≤n); Secondly,the degeneration,linear structures,nonlinearityand correlation immunity of multi-output functions are discussed.
