A Trusted VM-vTPM Live Migration Protocol in Clouds

Abstract

Security has been regarded as one of the greatest problems in the development of Cloud Computing. The trusted computing provides the hardware-based protection for cloud computing security based on TPM. While vTPM using in cloud environment still faces technical challenges, among which VM-vTPM live migration has been unsolved yet. In this paper, the trusted VM-vTPM live migration scene in clouds and its security and performance requirements are analyzed. Furthermore, a trusted VM-vTPM live migration protocol and its detailed design are presented. At last, the protocol was evaluated from the aspects of security and performance. As far as we know, the trusted VM-vTPM live migration protocol based on the pre-copy is firstly proposed in this paper.
