7元旋转对称2-弹性函数的构造
Concrete constructions of 2-resilient rotation symmetric Boolean functions with 7 variables
【摘要】 基于旋转对称轨道的数对分布矩阵的性质,给出了所有7元旋转对称2-弹性函数的具体构造。结果表明,在F27上有且仅有280个非线性旋转对称2-弹性函数。进一步地,对于任意的奇数k,在F27k上至少有280个非线性旋转对称2-弹性函数。
【Abstract】 Based on the properties of the 2-tuples distribution matrix of the rotation symmetric orbits,all 7-variable2-resilient rotation symmetric Boolean functions were constructed concretely.The results show that there are only 280nonlinear 2-resilient rotation symmetric Boolean functions overF27.Furthermore,there are at least 280 nonlinear2-resilient rotation symmetric Boolean functions over F27k for any odd number k.
