| 摘 要： | 利用函数单向S-粗集(function one direction singular rough sets),给出粗规律的概念,粗规律是被w(x)-,w(x)-构成的规律对{w(x)-,w(x)-};因为函数单向S-粗集的属性集{α-,α-}发生变化,粗规律{w(x)-,w(x)-}也发生变化.利用椭圆曲线,给出粗规律锁住概念,提出粗规律锁住定理,并给出应用.

| Abstract: | By employing function one direction singular rough sets,this paper presents the concept of rough law,which is the law pair consisting of lawsand.Rough law will change if the attribute setof function one direction S-rough sets has changed.By employing elliptic curve,the concept of one direction security of rough law and the theorem of one direction security of rough law are put forward,and the applications are given. |
