摘要 通过对网格环境中实体之间的信任关系进行分析,提出了一种信任值计算模型。该模型能根据用户和资源间已有执行经验计算节点的信任值,实现了网格环境下信任值的分布式计算,有效解决了网格动态性引起的信任值计算开销问题。 A trust value computation model is proposed based on the analysis of trust relationship in Grid. The trust value is computed according to users and resources experiences in this model and the distributed calculation of the trust value is implemented, therefore the overhead brought by the dynamics of the grid is solved.
