摘要 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。 To meet the demand of the delegation service during multi-domain authorization in grid computing, the delegation 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. The fine-grain authorization delegation policy is given. Finally, the simulation is given to prove the feasibility of the delegation model with trust level.
