摘要
给出了与文献[1]中所定义的有限域上多输出函数的非线性度不同的定义,并指出了它的密码学意义,也讨论了两者之间的关系,丰富了多输出函数方面的成果.
A new definition of the nonlinearity of multi-output functions over finite field is proposed,which is different from that in reference[1]. Its cryptographic significance is pointed out. The relationship between the two different kinds of nonlinearities is studied. The results about multi-output functions are enriched.
