摘　　要：研究了3种网格环境下的信任模型,比较了它们的建构思想、优越性和局限性,提出了定义身份权、使用身份权进行信任初始化、将信任推荐作为交易上下文环境的一种、扩大节点信任自主权以及建立独立信任管理层等改进想法,并在此基础上提出了改进后的新模型的框架.We firstly analyze three trust models in grid environment, compare their constructs, advantages and disadvantages, then bring forward some advice such as defining identity weight, realizing authentication in the initialization, regarding trust recommendation as one type of trade context, enhancing self - determination of grid entities and establishing trust management layer, and based on the former analysis develop framework of a novel grid trust model.
