Enabling Secure VM-VTPM Migration in Private Clouds

Free registration required

Executive Summary

The integration of Trusted Computing technologies into virtualized computing environments enables the hardware-based protection of private information and the detection of malicious software. Their use in virtual platforms, however, requires appropriate virtualization of their main component, the Trusted Platform Module (TPM) by means of virtual TPMs (vTPM). The challenge here is that the use of TPM virtualization should not impede classical platform processes such as Virtual Machine (VM) migration. In this paper, the authors consider the problem of enabling secure migration of vTPM-based virtual machines in private clouds. They detail the requirements that a secure VM-vTPM migration solution should satisfy in private virtualized environments and propose a vTPM key structure suitable for VM-vTPM migration.
