关于具有最大代数免疫性的$2k$ -变量对称布尔函数$k$

On $2k$-Variable Symmetric Boolean Functions with Maximum Algebraic Immunity $k$

Hui Wang, Jie Peng, Yuan Li, Haibin Kan

摘要:

布尔函数$f$的代数免疫定义为非零$g$使得$fg=0$或$(f+1)g=0$的最小次数.给定一个正偶数$n$,发现任何具有最大代数免疫度的$n$变量对称布尔函数$\frac{n}{2}$的权重分布都由$n$的二进制展开决定。在此基础上,构造了所有具有最大代数免疫度的$n$变量对称布尔函数.金额为$(2\wt(n)+1)2^{\lfloor \log_2 n \rfloor}$

英文摘要:

Algebraic immunity of Boolean function $f$ is defined as the minimal degree of a nonzero $g$ such that $fg=0$ or $(f+1)g=0$. Given a positive even integer $n$, it is found that the weight distribution of any $n$-variable symmetric Boolean function with maximum algebraic immunity $\frac{n}{2}$ is determined by the binary expansion of $n$. Based on the foregoing, all $n$-variable symmetric Boolean functions with maximum algebraic immunity are constructed. The amount is $(2\wt(n)+1)2^{\lfloor \log_2 n \rfloor}$
