摘要
多域环境下的访问控制是域间进行协作必须要解决的问题之一。本文对域间互操作的信任传播问题进行了分析,给出了自主策略、深度策略和角色策略。通过角色委托和角色映射,使角色的管理权和使用权分别传递。并对实现方案进行了讨论。
Access control in multi domain environments is one of the important issues of building coalition between domains. In this paper, the trust propagation issue for secure interoperability in multi domain environments is discussed. Then, the discretionary policy, depth policy and role policy are given. With role delegation and role mapping, the administrative and usage permissions of roles are transmitted separately. Finally, an implementation scheme is discussed.
