通过对旋转对称Boolean函数抵制快速代数攻击能力的研究，得到旋转对称]~olean函数的快速代数免疫不能达到最优．同时，构造了一些抵制快速代数攻击的能力非常不好的旋转对称Boolean函数．

英文摘要：

The resistance of rotation symmetric Boolean functions against fast algebraic attacks has been investigated in this paper. And it is concluded that the fast algebraic immunity of rotation symmetric Boole- an functions cannot achieve the optimum value. The results also showed that some rotation symmetric Bool- ean functions are vulnerable to fast algebraic attacks,
