摘　　要：为了减少任务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任务调度策略中,并综合考虑任务、资源双方的安全需求和系统的负载平衡,设计了调度算法Trust-based Min-min,仿真试验证明了该算法是合理的和有效的.In order to reduce additional grid overhead caused by conventional safety mechanisms, the task scheduling strategy has been proposed which incorporates trust relationship as a safety evaluation criterion into grid environments. Meanwhile, considering the security request of both the task and the resource and the load balancing of the system, we presented a scheduling algorithm called Trust-based Min-min. Simulation experiment has proved that the algorithm is reasonable and valid.
