摘要
计算机单机的安全问题已经非常重要,而BIOS的安全直接影响着计算机的安全。本文首先分析了PC机中BIOS的安全问题,对EFI/UEFI做了简述,分析了国内外研究现状,阐述了可信UEFIBIOS的定义,针对BIOS的安全问题提出一种利用可信平台控制模块(TPCM)在统一可扩展固件接口(UEFI)中建立信任链的方案,并对可信UEFIBIOS执行流程及信任链传递流程进行了分析,解决了BIOS信任链传递过程中遇到的各类安全问题。
The security of personal computer become more and more important,the security of BIOS affect the security of computers.This paper firstly analyzes the PC BIOS issue of security,describes something about EFI/UEFI,analyzes the research situation about UEFI BIOS,puts the definition about trusted UEFI BIOS,to the questions of BIOS security,bring forward a method of build trusted chain in UEFI and based on a trusted platform module（TPCM）,analyzes the implementation procedures of UEFI BIOS and transfer process of trusted chain,solves the security problems in trusted chain transmission of BIOS.
