| 摘 要： | 首先给出了网格计算中访问控制的特点和需求。现有的访问控制技术以及分布式授权模型,均不能满足网格计算中对访问控制的需求。通过建立实体间的信任关系,在CAS基础上,提出了基于信任度的访问控制机制。为了提高资源的利用率,提出了Ticket机制。最后给出模拟实验结果,验证有效性。

| Abstract: | This paper analyzed feature and requirement of access control for grid computing. Access control technologies and distributed authorization models that already had existed did not satisfy the requirement of access control in grid computing. By building trust relationship between entities, it put forward a trust based access control model for grid computing. In order to improve sharing of resource, introduced a Ticket method. At last, result of simulation experiments show that the trusted based access control mechanism can improve the rate of successfully accomplishing jobs. |
