考虑一个资源的访问策略,它只允许系统中拥有特定属性集的用户访问。具体来说,我们考虑这样的访问结构由某个单调函数(f:{0,1}^N)定义的情况 ightarrow {0,1}),属于某类函数(F)(例如合取、空间有界计算),其中N是可能属性的数量。
Consider an access policy for some resource which only allows access to users of the system who own a certain set of attributes. Specifically, we consider the case where such an access structure is defined by some monotone function (f:{0,1}^N ightarrow {0,1}), belonging to some class of function (F) (e.g. conjunctions, space bounded computation), where N is the number of possible attributes.
