TVMCM: A trusted VM clone model in cloud computing

In recent years, cloud computing becomes more and more popular and the technology of rapid cloning VMs is widely used to implement the fast instantiation of VMs to meet the need of bursting computational request. However, the security issue of VM cloning technology is not considered in current approaches. This paper proposes TVMCM, Trusted VM Clone Model. TVMCM is consisted of two individual models TCVMM and TCVDM where TCVMM ensures the security when cloning the memory of VM and TCVDM ensures the security when cloning the disk of VM. TVMCM resolves three problems: the identities verification of involved servers; the attestation of source VM and destination VM; the protection of integrity of transmitted data.
