n元Bent函数的级联构造
Concatenation Construction of Bent Function of n Variables
摘要
Abstract
Combining the concatenation method, a construction of Bent function of n variables from k Bent function is proposed. After analyzing the cryptographic properties of the Bent function of variables, a new construction method which is different from the original method and the reconstruction method is presented. The necessary and sufficient conditions of Bent function of n variables are derivated and validated. Based on the linear invariance of Bent function of n variables, a new set of Bent function is constructed.关键词
