摘　　要：针对可信网络,对其概念和性质进行了说明,并指出信任模型是可信网络研究的一大关键问题。对现有的各种信任模型进行了研究,详细阐述了各个信任模型的建模原理和建模过程,总结出了信任模型的研究方法和研究步骤。最后对比分析了各个模型的优缺点,指出了各个信任模型存在的局限性,为信任模型的完善和发展提供了意见,并提出需要根据不同的网络环境选择不同的信任模型,探讨了未来可信网络信任模型的改进与发展方向。Building an appropriate trust model for a network is an essential part in the research about trusted networks. The paper introduces the concept and properties of trusted networks,then focuses on the trust model.It analyzes six typical trust models in aspects of trust definition,clarification,calculation and propagation. With a comparison of these models,some important factors are found in building a trust model,which could help improve the performance of present trust models.It is also concluded that different models have different properties,andthe suitable model should be selected by considering the characteristics of the network.
