| 摘 要： | 提出了一个多安全域下基于角色的访问控制模型（MD-RBAC），该模型以基于角色的访问控制模型（RBAC）为基础，通过角色映射建立起访问控制要素间的关联，并引入有效性约束和基于有效性约束的边界策略对跨域访问的风险进行识别和防护。最后，将MD-RBAC模型与另一个多域环境下的访问控制模型I-RBAC 2000进行了比较。

| Abstract: | Mutil Domain-Role Based Access Control(MD-RBAC)model was proposed.MD-RBAC was based on Role-Based Access Control(RBAC)model,building relations between access control elements of different domains.Besides,the model introduced validation constrains and border policy,which was based on validation constrains,in order to identify and defense the risks that were brought in by inter-domain access.Finally,we briefly compared MD-RBAC model to another access control model I-RBAC 2000 which also aimed to solve access ... |
