Abstract: A trusted agent with using Platform Configuration Register（PCR） in trusted computing specifications is introduced into our architecture.The hierarchy of the agent in the whole software and hardware system is pointed out，which consists of three main modules.This method explains the content of exchange protocol in order to build trust in mutual system platform.Also give a statement of the enhancement of the security of peer-to-peer network computing.An approach of constructing network trusted path in secure operating system is addressed.Point out some related future research fields at last.

摘要： 基于可信计算技术提出了一个具有时间自校验功能的信任代理模块，并将它引入到提出的框架中。给出了它在系统中的层次位置，同时指出了该模块包括的3个主要部分以及它们的功能。框架可以保证平台协议交换的可靠性，并能保证检测环境提供信息的可靠性。指出了该算法如何加强平台访问控制和应用程序的安全性，并说明了该算法如何增强对等网络计算的安全性以及设计安全操作系统的网络可信路径方法，最后提出了一些相关的未来研究方向。
