Document Type and Number:

WIPO Patent Application WO/2015/180396

Kind Code:

A1

Abstract:

Provided in an embodiment of the present invention are a virtual trusted platform module (vTPM) function realization method and management device. The method is implemented in an abnormal hierarchy EL3 of a processor employing ARM V8 architecture, and comprises: according to the requirements of one or more VMs, generating one or more vTPM instances corresponding to each VM, and storing the generated one or more vTPM instances in a preset safe space, each vTPM instance having a specified instance communication queue for the corresponding VM to use, and each instance communication queue being allocated with a physical address; interacting with the VMM and the VM to enable the VM to acquire the communication queue virtual address of the VM corresponding to the communication queue physical address of the vTPM instance in the virtual address space of the VM, and to enable the VM to communicate with the communication queue of the vTPM instance via the communication queue virtual address of the VM, thus reducing time delay and improving processing efficiency.
