    摘要: 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.

    摘要: 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.

    摘要: 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.
