中文摘要：

可信网络连接是面对传统的网络信息安全系统的不足而提出的,采取了主动的防御保护措施。可信度的评估是可信网络的一个重要环节,提出了基于可信度的层次化评估模型,将可信度按照不同的影响因素进行分层,并使用层次分析法（AHP）对可信度进行量化分析。首先建立可信度的层次化评估模型,然后对提出的可信度层次评估模型进行量化分析,最终经过分析计算出各因素对可信度的具体影响数值。根据数值分析,对可信度进行评估。

英文摘要：

Face of the shortage of the traditional network information security system,we put forward the conception of Trusted Network Connect.We take the initiative of the defense protection measures.The assessment of the credibility is an important part of the trusted network.In this paper,we propose the model of assessment based on credibility of the hierarchy,and credibility is divided by different factors.We measure and analyze the credibility by AHP.First,we should establish the model of assessment based on credibility of hierarchical.Second,we should measure and analyze the model.Finally,we must calculate all number which is affect by all credible factors.According to the numerical analysis,the credibility is accessed.
