Abstract: The properties of Boolean functions such as resiliency order,algebraic immunity,algebraic,nonlinearity,and the relationships among them are still small.The satured Best Boolean functions are important in stream ciphers,in this paper,it is demonstrated that the 5-variable satured Best Boolean functions are 2-order algebraic immunity,which are given in lemma 8 of reference [1],based on this result,it is improved.

Key words: Boolean function, satured Best functions, annihilator, algebraic immunity

摘要: 关于布尔函数的代数免疫性与弹性、代数次数、非线性度之间的关系的结果至今仍然很少,饱和最优布尔函数在流密码领域具有较高的理论价值,通过计算证明文献[1]中命题8给出的5元最优布尔函数都是2阶代数免疫函数,并在此基础上对这个结果做了进一步推广。
