| 摘 要： | 在基于角色的访问控制RBAC模型中，通过角色将用户和权限相联系，极大降低了授权管理的复杂性，不失为一种灵活有效的安全措施。作为PKI技术新发展的X.509属性证书，提供了一种较好的机制来支持这一模型。首先对RBAC模型和属性证书的有关特性分别进行了介绍，而后就属性证书在RBAC中的应用进行了分析研究。

| Abstract: | By means of role,the access control model of role-based access control links an user with his permissions,which greatly reduces the complexity and cost of authorization managements.Attribute certificate,as a new development of Public Key Infrastructure(PKI),comes up with a potential mechanism to support the model.After introducing the properties of RBAC model and attribute certificate,this paper analyzes and discusses the application of attribute certificate in the RBAC. |
