摘要
在探讨密码学中布尔函数性质的基础上,提出了一个具有高代数免疫阶布尔函数的构造方法,利用这种方法可以构造出一类具有高代数免疫阶的布尔函数,并给出了一个实例。
The currently known constructions of Boolean functions with high nonlinearities, high alge- braic degrees and high resiliency orders do not seem to permit achieving sufficiently high algebraic immunity. A construction of Boolean functions is proposed based on cryptograph properties of Boolean functions. A new class of functions are built by this method, and the constructed functions have the same algebraic immunity as the given function. In the end, applying this construction we obtain eight 3-variable functions with algebraic immunity 2(maximum possible algebraic immunity).
