Shared access to a trusted platform module by a hypervisor and a guest operating system

摘要

Examples relate to a hardware hypervisor that facilitates shared access to a Trusted Platform Module ("TPM") by the hypervisor and a guest operating system ("OS"). In some examples, the hypervisor implements machine readable instructions that cause the hypervisor to: access the TPM prior to boot of the guest OS; obtain a software encryption key stored at the TPM; determine, using the software encryption key, the software identity from an external storage; and leave the TPM in a state compatible for the guest OS.
