基于TCM标准的可信计算平台,借鉴可信计算组织(TCG)的可信网络连接技术(TNC)规范,提出了一种可信网络接入认证模型,该模型在TNC三层模型上增加了一层系统恢复层,采用先评估再接入认证的方法,即客户端首先对自己进行评估,只有在认为自己可信的情形下才向策略决定点申请接入请求,提高了接入认证效率,同时对于TNC模型中拒绝接入的客户端采取了更柔性的策略,提高了网络的健壮性。
Based on the TCM standard trusted computing platform, Trusted Computing Group (TCG) Trusted Network Connection (TNC) specification, a trusted network access authentication model is proposed, which adds TNC three-layer model A layer of system recovery layer, using the first assessment of re-access authentication method, that is, the client first to evaluate themselves, only in the case of their credibility to the decision point to apply for an access request to improve the efficiency of access authentication , And at the same time, adopted a more flexible strategy for clients denied access in the TNC model to improve the robustness of the network.
