================
Xen的虚拟TPM接口
================
作者:Matthew Fioravante (JHUAPL), Daniel De Graaf (NSA)
本文档描述了用于Xen的虚拟可信平台模块(vTPM)子系统。假定读者熟悉
Xen和Linux的构建和安装,并对TPM和vTPM概念有基本的理解。
介绍
----
这项工作的目标是为虚拟客户操作系统(在Xen中称为DomU)提供TPM功能。这使得
程序能够像与物理系统上的TPM交互一样,与虚拟系统中的TPM进行交互。每个客户
操作系统都会获得一个唯一的、模拟的软件TPM。然而,vTPM的所有秘密(如密钥、
NVRAM 等)由vTPM管理域进行管理,该域将这些秘密封存到物理TPM中。如果创建这
些域(管理域、vTPM域和客户域)的过程是可信的,vTPM子系统就能将根植于硬件
TPM的信任链扩展到Xen中的虚拟机。vTPM的每个主要组件都作为一个独立的域实现,
从而通过虚拟机监控程序(hypervisor)提供安全隔离。
这个mini-os vTPM 子系统是建立在IBM和Intel公司之前的vTPM工作基础上的。

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
