Abstract: A trust valuation model has been presented.In order to reduce additional grid overhead caused by conventional safety mechanisms,a resource selection strategy has been proposed which incorporates trust relationship as a safety evaluation criterion into grid environments.TRM-schedule,a resource selection algorithm has been also presented.Simulation experiment has proved that the algorithm is reasonalble and valid.

Key words: tust, resource selection, computational grid

摘要： 提出一个信任评估模型。为了减少资源调度过程中使用传统安全措施带来的网格开销,提出把信任关系作为安全衡量标准融入网格环境下的资源调度策略中。设计了一个融入信任关系的资源映射算法TRM-Schedule,仿真试验证明了算法的合理性和有效性。
