基于智能卡的主机可信赖平台的建立

Establishment of Trusted Platform of PC Based on Intelligent Card

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。

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 terlninal. 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 misted platform based on PC.
