An improved vTPM migration protocol based trusted channel

Abstract

One of the most important benefits of virtualization is Virtual Machine (VM) migration. While the performance of live VM migration is well explored, the security aspects have received very little attention. The extension of trusted computing to virtual systems using vTPMs allows applications in the VM to use the vTPM for secure storage and reporting platform integrity. In this paper, we propose an improved secure vTPM migration protocol using a trusted channel and property-based attestation of destination platform to assure the security requirements of the vTPM migration.
