摘要:

为实现访问控制中客体对主体预授权的准确和及时,针对基于信任的访问控制信任和权限的映射问题,将成功交互的实体授权信息作为用于知识发现的数据决策信息表,结合访问控制的授权规则,提出了一种基于粗糙集的授权规则知识发现方法,实现授权规则中的属性约简、知识决策规则的提取.最后,通过算例分析验证了基于粗糙集的授权规则知识发现方法的有效性.

关键词: 访问控制, 粗糙集, 知识发现, 属性约简, 授权规则

Abstract:

To achieve accurate and timely pre-authorization of access from a subject to an object in access control, a method on knowledge discovery of authorization rules was proposed based on rough set theory to reduce knowledge attributes and to extract decision rules. According to the main characteristics of mappings between trust levels and access rights in trust based access control and combined with access authorization rules, this method makes successful use of the interactive entity authorization information as the data decision information table for the discovery of knowledge. Analysis shows that both the knowledge discovery method and the rough set based authorization rules are effective.

Key words: access control, rough set, knowledge discovery, attribute reduction, authorization rule
