结果表明,n变量的布尔组合函数f(x)是mth-order相关性 - 免疫时,并且只有当它的walsh变换f(欧米茄)的所有欧米茄(Omega)消失,其锤子的重量在1和m之间消失,包括1和m。该结果用于扩展稍微siegenthaler的(IEEETrans。Comput。,vol。C-34,pp。81-85,1985年1月)的表征,对相关 - 免疫组合函数的代数正常形式的表征。 >
It is shown that a Boolean combining function f(x) of n variables is mth-order correlation-immune if and only if its Walsh transform F( omega ) vanishes for all omega with Hamming weight between 1 and m, inclusive. This result is used to extend slightly Siegenthaler's (IEEE Trans. Comput., vol. C-34, pp. 81-85, Jan. 1985) characterization of the algebraic normal form of correlation-immune combining functions. >
