In order to solve the problem of the establishment of network trust, this paper brings up a trusted network model based on Trusted Platform Module(TPM) security chip, which is based on the theory of trusted computing and trusted network access technology. This model describes the establishment of trusted chain and expands the trusted chain to the network, then gives the model structure and information flow analysis, and makes the trust of metric computation. Through performance analysis, results show that the network model has a strong robustness and high credibility.%针对网络中可信模型的建立问题,在现有可信计算理论、可信网络接入技术基础上,提出一种基于可信平台模块安全芯片的可信网络模型.该模型从终端建立可信链并将其传递到网络中,给出模型的架构及信息流分析,对信任度的度量进行形式化计算.性能分析结果显示,该网络模型具有较强的健壮性和较高的可信度.
