摘要
Sarka等人在文献[1]中给出了弹性布尔函数的一种构造方法,利用该方法可以构造出非线性度、弹性阶和代数次数等密码学性质均较理想的奇数元弹性布尔函数。对其构造得到的弹性布尔函数的谱值分布进行了研究,分析了由该方法所构造得到的5元1阶和7元1阶弹性布尔函数的谱值,给出了这两类弹性布尔函数的谱值分布情形,并给出了相应谱值点的计数结果。
Sarka has given a construction of odd-variables resilient Boolean functions in [1],which have high nonlinearity, good resiliency and maximum possible algebraic degree.The Walsh spectrum distributing of these resilient Boolean functions is studied.The Walsh spectrum distributing of 5-variables 1-resilient and 7-variables 1-resilient Boolean functions which were constructed in [1] is analyzed.And the numeration of the Walsh spectrum is given.
