严格择多逻辑函数的密码学特征
CRYPTOLOGICAL CHARACTERIZATION OF THE STRICT MAJORITY LOGIC FUNCTIONS
-
摘要: 本文主要讨论了当n=2m+1(m1)时,n阶严格择多逻辑函数的代数正规形式中,所有的阶为k((n+1)/2kn-1)的非线性项都出现,从而从密码学角度来说,这种函数有好的密码学特征。

Abstract: It is proved that in the algebraic normal form of the strict majority logic function with order n= 2m+1(m1), all the nonlinear terms of k-th order, (n+1)/2kn-1, must appear. Threrfore, from the view of cryptology, such strict majority logic function has good characteristics. -
