To meet the demand of the delegation service during multi-domain authorization in grid computing,the dele-gation negotiation process is presented to realize the authorization delegation of role and permission based on the RBDM and RT model through the introduction of trust levels.
针对网格计算环境下跨域授权过程的委托服务需求,在现有的RBDM和RT模型基础上,结合主观信任机制对委托过程进行信任协商,实现角色和权限的授权委托过程,并给出了细粒度的授权委托策略,最后对委托过程中的主观信任机制进行仿真,证实了使用信任度实现对委托过程控制的有效性。
