| 摘 要： | 明确给出了网格环境下信任的定义，详细分析了信任属性。根据网格的特点，提出了以域为单位的两层信任模型，包括域间信任关系和域内信任关系，着重介绍了域间信任的计算模型。在信任计算模型中，信任评估采用基于贝叶斯评估方法；对信任的推荐采用基于PageRank技术的全局推荐信任计算。最后给出了应用中综合评估信任度的策略。

| Abstract: | Gives a definition of trust for grid computing and analyses properties of trust. A two layers trust model that takes domain as unit is presented. This trust model includes trust relationship between domains and trust relationship in domain. This paper mainly discusses the trust relationship between domains. In this model, trust valuation that bases on Bayesian approach is presented. For trust recommendation, this model uses PageRank technology to computing global reputation. At last, this paper gives a kind of policy that how to make decision in grid application. |
