网格计算环境的一种基于信任度的授权委托机制
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。
Abstract
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.The fine-grain authorization delegation policy is given.Finally
the simulation is given to prove the feasibility of the delegation model with trust level.
