A data processing system features a hardware trusted platform module (TPM), and a virtual TPM (vTPM) manager. When executed, the vTPM manager detects a first request from a service virtual machine (VM) in the processing system, the first request to involve access to the hardware TPM (hTPM). In response, the vTPM manager automatically determines whether the first request should be allowed, based on filter rules identifying allowed or disallowed operations for the hTPM. The vTPM manager may also detect a second request to involve access to a software TPM (sTPM) in the processing system. In response, the vTPM manager may automatically determine whether the second request should be allowed, based on a second filter list identifying allowed or disallowed operations for the sTPM. Other embodiments are described and claimed.

Methods and apparatus supporting access to physical and virtual trusted platform modules

The present subject matter is related to trusted computing, and more particularly to migration of virtual trusted platform module keys that are rooted in a hardware trusted platform module. Some embodiments include a trusted platform virtualization module that may perform one or more of inbound and outbound trusted platform module key migrations. Such migrations may be performed between a virtual trusted platform module and either a hardware or a virtual trusted platform module.

Virtual TPM key migration using hardware keys

The present subject matter related to trusted computing, and more particularly, to virtual trusted platform module keys rooted in a hardware trusted platform module. Some embodiments include a trusted platform virtualization module operable to capture virtual machine trusted platform module calls and operates to generate, maintain, and utilize hardware trusted platform module keys on behalf of the one or more virtual machines. Some embodiments include virtual trusted platform module keys having a public portion on top of an private portion including an encrypted hardware trusted platform module key.

Virtual TPM keys rooted in a hardware TPM

A processing system with a trusted platform module (TPM) supports migration of digital keys. For instance, an application in the processing system may create a first configuration key as a child of a TPM storage root key (SRK) when the processing system has a first configuration. The application may also create an upgradable root user key associated with an upgrade authority as a child of the first configuration key. The application may also create a user key as a child of the upgradable root user key. When the processing system has a second configuration, the application may create a second configuration key as a child of the SRK. The application may request migration approval from the upgrade authority. In response to receiving the approval from the upgrade authority, the application may migrate the root user key to be a child of the second configuration key. Other embodiments are described and claimed.

Methods and apparatus for providing upgradeable key bindings for trusted platform modules

A data processing system isolates a virtual trusted platform module (vTPM) manager in the processing system from other management software in the processing system. In one example process, the processing system launches a virtual machine monitor (VMM) that includes a memory-mapped input/output (MMIO) trap. The processing system also launches a vTPM manager in a first virtual machine (VM). In addition, the processing system launches a second VM to contain virtual machine management programs other than the vTPM manager and the MMIO trap. Other embodiments are described and claimed.

Methods and apparatus for creating an isolated partition for a virtual trusted platform module

Systems, methods and machine readable media for configuring virtual platform modules are disclosed. One method includes launching a virtual machine monitor, and determining, with the virtual machine monitor, whether a configuration policy that defines a configuration for a virtual trusted platform module is trusted. The method further includes configuring the virtual trusted platform module per the configuration policy in response to the virtual machine monitor determining that the configuration policy is trusted. The method also includes launching, via the virtual machine monitor, a virtual machine associated with the virtual trusted platform module.
