奇数元二阶相关免疫对称布尔函数的构造
Constructions of odd variables symmetric boolean functions with second-order correlation-immunity
【摘要】 n元m阶相关免疫对称函数的构造等价于方程sum Cn-2iXi from i=0 to (n-2)=sum Cn-2iXi+1 from i=0 to (n-2)在二元域上的求解。通过对该方程及其等价方程解的关系讨论,给出了构造奇数元二阶相关免疫对称函数的算法。
【Abstract】 Constructions of n-variable symmetric Boolean functions with second-order correlation-immunity is equivalent to solve the eqution sum Cn-2iXi from i=0 to (n-2)=sum Cn-2iXi+1 from i=0 to (n-2) in the binary field. By discussing the relationship between the solutions of the equation and its equivalent equation, an algorithm of constructing odd-variable symmetric Boolean functions with second-order correlation-immunity is proposed.
