%X <p>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.</p>
