中文摘要：

在对相关信任模型研究的基础上，提出了一个基于多Agent的信任模型，该模型采用在每个管理域设置多个Agent，每个实体和多个Agent关联的方式来管理网格环境中实体间的信任关系。实验和分析结果表明，与其它基于声誉的信任模型相比，这种模型不但缩短了交易响应时间，而且提高了作业成功率，从而能更加有效地解决网格环境中存在的安全问题。

英文摘要：

Based on the relate research, a new trust model is developed, which insists on multiple Agents in each aomaln.The entities are distributed across these Agents, with each of these entities being associated with more than one Agent. By doing this, the model can not only shorten the response time between entities, but also improve the success rate of transaction, thus can resolve security problems exist in grid environment more effectively, which is verified by simulated experiments.
