摘要
本文分析了重量为4k+2的相关免疫布尔函数的线性结构,证明了这类函数的退化性和线性结构是等价的,给出了重量为4k+2的非退化的相关免疫布尔函数的精确计数。
Based on the analysis of the linear structure of correlation immune functions for the case of weight 4k+2, the paper proves that the degeneration and the linear structure of such functions are equivalent, then gives the exact number of nondegenerated correlationimmune functions for the case of weight 4k+2.
