Abstract:
In at least one embodiment, a method for secured rollback of a virtual Trusted Platform Module (vTPM) that renders available functionalities offered by Trusted Platform Module (TPM) on a computer to a virtual machine (VM) is provided. The method includes taking and saving a snapshot of current state of a virtual machine as well as a snapshot of the corresponding vTPM, upon receiving a request for taking a snapshot of the virtual machine. The method further includes converting the snapshots into the current state of the virtual machine and the current state of the vTPM, respectively, upon receiving a request to roll back the virtual machine.
