    • A system and method to support platform firmware as a trusted process. Measurement of a trusted portion of original firmware are measured by a core root of trust measurement (CRTM). The measurement is stored in a secure manner during pre-boot. During operating system (OS)-runtime, requests are made to access an unqualified current version of firmware corresponding to a secure execution mode. A portion of the current firmware analogous to the trusted portion is measured. The measurements of the trusted original portion and unqualified current portion are compared to verify they match. If they match, it indicates that the current portion and the trusted portion are one in the same. Thus, the current portion of firmware is trustworthy. Accordingly, the firmware may be executed as a trusted process. Embodiments employ locality to enforce the trusted process. The use of locality prevents unqualified users (i.e., software) from accessing data stored by trusted firmware.
    • 将平台固件支持为可信过程的系统和方法。 原始固件的受信任部分的测量是通过信任测量(CRTM)的核心根来测量的。 在预引导期间,以安全的方式存储测量。 在操作系统(OS) - 运行时期间,请求访问对应于安全执行模式的不合格的当前版本的固件。 测量与可信部分类似的当前固件的一部分。 比较可信原始部分和不合格的当前部分的测量结果,以验证它们是否匹配。 如果它们匹配,则表示当前部分和可信部分是相同的。 因此,固件的当前部分是值得信赖的。 因此,固件可以作为可信过程来执行。 实施例采用本地来强制可信过程。 使用本地防止不合格用户(即,软件)访问由可信固件存储的数据。
