摘要 网格由广域分布的、异构的计算资源组成,将任务分配给远程节点执行常会引起多种安全问题,因此需要有效的任务管理机制保证任务和资源的安全性和可靠性。提出一种基于多步直接传播的网格信任模型,模型根据用户和资源间已有执行经验对信任值的影响,采用多步直接传播方式计算节点信任值,实现了信任值的分布式计算,有效解决因网格动态性引起的信任值计算开销问题。 Grid resources are heterogeneous, geographically distributed and dynamically available. A job dispatched to a remote site may fail due to experiencing some infections or malicious attacks, and therefore a judicious job management mechanism is needed to engage in the security and privacy concerns. In this paper, a trust computing model based on the multi-step propagate mechanism is proposod. The trust value is ealculated according to the execution experiences between users and resources, and the distributed ealeulation of the trust value is implemented, therefore the overhead brought by the dynamics of the Grid is decreased.
