Abstract
With growing of cloud computing, security of virtual machines also increases due to malicious insiders and external attackers. Virtual machines (VMs) in cloud computing need to be protected, since they are hosting critical data. In this paper, we propose trusted model for VM security in cloud computing. In our model, we encrypt the VM image and store in cloud, and it stops inside attackers from violating the confidentiality. Then, trusted third party (TTP) keeps on monitoring the VMs in cloud for integrity of VMs. Further, we are improving the availability of virtual machines using snapshot technique. Snapshot is very useful when VM is lost. Through security analysis, we prove confidentiality, integrity, and availability of VM. We evaluate the performance of our scheme in performance analysis.
