Due to the dynamics and uncertainty of grid environment,trust problem in grid environment is an important topic in currently grid research.This paper proposed a trust evaluation model based on entity behaviors in grid environment,it discriminated the trust relationships between entities in the same autonomous domain and in different domains.The model also led into cheat punishment mechanism,guaranteed the security of the entity in grid.The simulation result shows that it can evaluate the trust relationships between entities more precisely,thus can resolve security problems existed in grid environment more effectively.
