摘要： 传统意义上的TPM(可信任平台模型)的建立都基于固化在主板之上的安全芯片，这就使没有安全芯片的主机无法获得面向终端安全的“可信计算”。文章提出了一种利用USB 插口的智能卡代替安全芯片作用的主机可信赖平台建立方案，以扩充主机可信赖平台的实现途径。

Abstract: The traditional method for establishing a TPM system is based on a security chip fixed on the main-board, so the PC without a security chip can’t obtain the “trusted compute” objecting terminal. This paper raises a scheme to establish a “TPM” system without a security card by using an intelligent card (USB), and this scheme will spread the approach to realize a trusted platform based on PC
