E-导数在研究布尔函数的密码学性质中的应用

Applicatons of E-derivative in the study of cryptographic properties of Boolean Function

为了更好地揭示布尔函数的密码学性质,文章将引入布尔函数的导数这一定义,它能和导数一起全面揭示布尔函数的密码学性质和结构的关系。文章主要对关系密码系统安全性能的平衡布尔函数的相关免疫性以及E-导数的密码学性质进行了研究。

In order to better reveal the eryptographie properties of Boolean Function, e-derivative is introduced to fully reveal the relationship between eryptographie properties and structure . This paper mainly studies the correlation-immunity of balanced H Boolean Functions as well as its cryptographic properties in cryptographic system.
