碩士 === 國立臺灣科技大學 === 電子工程技術研究所 === 83 === Traditional access control policy is based on entity (i.e. ject). For a large dynamic system, the access control mechanism an immense mutable access control matrix because of the fact that ntity of entity is immense; (2) the subject, object, and access ated very often. In this dissertation, we will solve the above problem based on policy. By role classification, we classify all entities intoch have the properties of less quantity and more stable. Role-based change original access control mechanism into a more simplified access control matrix to provide a more efficient and simple mangement. In this dissertation, we also propose a role-based hierarchy improve the traditional user hierarchy authorization policy. The new hierarchy structure is role instead of user. Role hierarchy more simplified and stable than the conventional user hierarchy thermore, by the following authorization rules: (1) upper levelin- ate lower level role; (2) authorization from low to up level;
