摘要
定义单向粗关系并刻画它的结构,该结构保留了S-粗集的基本特性,而且粗集的等价类也被一般关系剖分的子块所替代。作为应用实例,设计了一个形式算法,实现对数据通讯的数字签章和认证。
A one-direction rough relations is defined and its structure is depicted which reserves the basic features of S-rough sets. The sub-blocks by divide relation are used to substitute the equivalent class of rough sets. The article designs a formalized arithmetic to realize the numeric signature and authentication on data communication.
