摘　　要：教育资源网格的动态性、开放性等特点为其带来了很多的安全隐患,本文基于模糊理论提出了一个教育资源网格信任模型。模型中信任分为直接信任和间接信任,在教育资源网格信任模型的基础上改进了信任值的计算,可以得出更有效的信任度,提高交易的成功率。实验结果显示了模型的有效性。Educational Resource Grid has a lot of security risks because of its being dynamic,open and so on.Therefore Trust Model of Educational Resource Grid based on fuzzy theory is brought out.Trust has been divided into direct trust and indirect trust in the model.Improve the calculation of trust value on the basis of Trust Model of Educational Resource Grid to get more valid trust value and improve the success rate of transactions.Experimental results show the validity of the model.
