摘要
平衡性和相关免疫性是函数的两个重要密码特性 ,但目前对两者之间的关系还没有得到很好地研究 .本文拟对布尔函数的平衡性和相关免疫性之间的关系作一些探讨 ,引进相对平衡性的概念 ,讨论相对平衡与通常的平衡概念的关系 。
Both balancedness and correlation immunity is one of the most important cryptographic characteristics of a Boolean function to which have gotten many researches respectively. But there has not been a good discussion for the relationship between them. In the present paper, we introduced the idea of relative balanced functions, probed into the relationship of that and the normal balancedness, and then got a characterization of correlation immunity by relative balancedness.
