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.
