H A Dxen-tpmfront.rst7 This document describes the virtual Trusted Platform Module (vTPM) subsystem for
9 Linux, and a basic understanding of the TPM and vTPM concepts.
18 of the vTPM's secrets (Keys, NVRAM, etc) are managed by a vTPM Manager domain,
20 these domains (manager, vTPM, and guest) is trusted, the vTPM subsystem extends
22 major component of vTPM is implemented as a separate domain, providing secure
23 separation guaranteed by the hypervisor. The vTPM domains are implemented in
26 This mini-os vTPM subsystem was built on top of the previous vTPM work done by
