  • Methods and apparatus supporting access to physical and virtual trusted platform modules
    Patent number: 8584229
    Abstract: 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 For Creating An Isolated Partition For A Virtual Trusted Platform Module
    Publication number: 20120030676
    Abstract: 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.

    Abstract: 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.
