Abstract: The paper proposes a grid trust model that deduces and synthesizes the values of trust with the subjective logic theory. It designs a kind of scheduling algorithm of task security level matching resource security level for resolving the problems of grid task scheduling algorithm at present. The algorithm screens resources with the security requirements, and makes it meet the earliest finish time. Simulation results indicate that the algorithm increases the task success ratio and reduces the job finish time. Therefore it is an efficient scheduling algorithm for scheduling in grid environment.
