摘　　要：TCG MTM规范的发布,确保了移动终端的安全性,但MTM芯片的推广导致移动终端通信方式的改变,从而提出移动互联网下可信移动平台(带有MTM芯片的移动终端,TMP)的接入机制,该机制在服务域中引入策略决策者管理本域的TMP及Internet服务提供商,定义了移动互联网下TMP的2种访问模式──本域服务和跨域访问,并详细介绍各模式的具体工作流程,其中将跨域访问模式定义为漫游服务和资源请求2种场景,重点描述TMP接入机制的可信性认证体系。运用通用可组合安全模型对TMP的2种访问方式进行安全性分析,分析表明,该机制可安全实现移动互联网下TMP的可信接入,同时具有实用、高效的特点。The publication of TCG MTM standard ensured the safety of mobile terminal and its promotion results in the changes of communication on mobile terminals.An access mechanism to trusted mobile platform（mobile terminals with MTM chips,TMP） was proposed on mobile Internet.This mechanism defined an extended service set as a service field,introduced TMP and Internet ISP of strategy decider management field,and defined two visit mode of TMP on mobile Internet,self field service and cross field visit.The progress of each mode was described in details.Cross field visit mode was defined as roaming service and resource request.The trusted evaluation system of TMP access mechanism was specifically described.Universal combinational safe mode was used to analyze the safety of the two TMP access.The analysis shows that this mechanism brings about trusted TMP access on mobile Internet and is safe,practical and high efficient.
