Trust has been recognized as an important factor for scheduling in Grid. With a trust-aware model, task scheduling is crucial to achieving high performance. In this paper, a trust model adapted to the Grid environment is proposed and a scheduling algorithm based on the trust mechanism is developed. In the trust model, trust value is computed based on the execution experiences between users and resources. Based on the trust model Min-min algorithm are enhanced to ensure the resource and application security during the scheduling. Simulation results indicate that the algorithm can remarkably lessen the risks in the task scheduling, improve the load balance and decrease the completion time of tasks, therefore it is an efficient scheduling algorithm in trust aware Grid system.
