| 摘 要： | 目前的可信计算研究方案,比较多地强调应用TPM模块,但对TPM模块自身的可靠性和稳定性等考虑的较少,若TPM发生故障,则整个系统就无法正常工作,同时用户的一些重要信息也不能恢复。文中提出了一种基于USB KEY和BIOS的安全解决方案,当TPM故障时,调用禁用TPM模块,使TPM进入功能禁用状态,不进行度量操作,计算机进入非可信工作模式;在启动过程中,利用USB KEY和访问控制模块,实现在BIOS层的身份认证;利用保存在USB KEY里的相关密钥,恢复用户的一些重要信息。

| Abstract: | At present, more and more attention has been given to trusted platform module in the trusted computing research projects while its security and stability are concerned less. If TPM is damaged, the whole system can not work normally and the users＇ important information can not be restored, too. In this paper, a secure solution based on USB KEY and BIOS is brought forward. Invoke forbidden TPM module to disable TPM so that the work of measurement will not be performed which can lead system into non-trusted mode. Besides, using USB KEY together with access control module to carry out access control. At the same time, use the related keys stored in TPM to recover the users＇ important information. |
