摘要
相关免疫函数在密码通信、计算机安全等诸多领域有着广泛的应用 .自TSiegen thaler提出该概念以来 ,找到简便易行的构造相关免疫函数的方法一直是一个十分活跃的研究领域 .本文用级联的方法 ,从低阶相关免疫函数来构造高阶的相关免疫函数 ,由此得到几种构造任何阶相关免疫函数的简便方案 ,推广了文献 [4。
Correlation immune functions have many applications in cryptology and computer security practices.Finding methods for easy construction of correlation immune functions has been an active research area since the introduction of the notion by T Siegenthaler.In this paper,we study a concatenation method by which we get higher order correlation immune function from two lower order ones,and therefore extend the results in references[4,5].
