在UC框架下,研究了可信网络连接(TNC)协议.首先,设计了TNC理想函数F_(TNC),EAP认证理想函数F_(EAP)以及EAP-TNC理想函数F_(E-PA),构造了通用可组合的可信网络连接安全模型.其次,在(F_(EAP),F_(E-PA))-混合模型下提出了通用可组合安全的TNC协议TK-TNC.然后,通过安全性分析,得出D-H PN协议不能实现理想函数F_(E-PA).最后,使用Twin DH交换技术设计了TD-H PN协议.通过证明分析,结果表明TK-TNC在(F_(EAP),F_(E-PA))-混合模型下安全实现F_(TNC);基于CDH假设,TD-H PN可以在(F_(REG),F_(CERT))-混合模型下安全实现F_(E-PA).
Under the framework of UC, the Trusted Network Connection (TNC) protocol is studied.Firstly, TNC, EAP and E_PA are designed, and TNC, F_ (E-PA) A universal combinable trusted network connection security model is proposed.Secondly, a universal combinable secure TNC protocol TK-TNC is proposed under (F_ (EAP), F_ (E-PA) (E-PA) .Finally, TD-H PN protocol was designed by using Twin DH exchange technology. The results show that TK-TNC has a good performance in F_ (EAP), F_ (E-PA) -Mixed model, F_ (TNC) can be safely implemented based on the hybrid model. Based on the CDH assumption, TD-H PN can safely implement F_ (E_ PA) .
