| 摘 要： | 讨论了基于角色的访问控制策略在多域安全应用中的互操作问题，提出了多域应用环境下角色映射的概念，建立了一个基于角色的组合层次关系的多域授权管理模型，通过约束条件和授权步给出了跨域用户的授权访问控制策略，实现了多域环境的安全互操作．该模型不仅使授权机制易于实现，而且可以灵活地适应应用中安全需求的变化。

| Abstract: | This paper discussed the secure interoperability in multi-domain application. Based on RBAC access control model, a concept of role translation within multi-domain application environment was proposed. A multi-domain authorization management model of combined hierarchy based on RBAC was established and User-Role assignment over cross-domain was given through constraints and authorization steps. This model is not only easily realized, but also is flexibly adapted to the change of security requirement in applications. |
