Abstract: Due to the dynamics and uncertainty of grid environment,trust problem in grid environment is an important topic in currently grid research.Proposes a trust model,it discriminates the trust relationships between entities in the same autonomous domain and in different domains.The simulation results show that the trust relationships between entities can be evaluated more precisely,thus security problems exist in grid environment can be resolved more effectively.

Key words: grid, security, trust

摘要: 面对网格环境的动态性和不确定性,网格安全因素变得尤为重要。提出了一种基于信任度的模型来评估网格环境中实体之间的信任关系。仿真结果表明,这种信任模型能更加准确地评估实体之间的信任关系,从而更加有效地解决网格环境中存在的安全问题。
