A trusted measurement model based on dynamic policy and privacy protection in IaaS security domain

In Infrastructure as a Service (IaaS) environments, the user virtual machine is the user’s private property. However, in the case of privacy protection, how to ensure the security of files in the user virtual machine and the user virtual machine’s behavior does not affect other virtual machines; it is a major challenge. This paper presents a trusted measurement model based on dynamic policy and privacy protection in IaaS security domain, called TMMDP. The model first proposed a measure architecture, where it defines the trusted measurement of the user virtual machine into the trust of files in the virtual machine and trusted network behavior. The trusted measure was detected through the front-end and back-end modules. It then describes in detail the process of the trusted measurement in the two modules. Because the front-end module is in the guest virtual machine, it also describes the protocol to ensure the integrity of the module. Finally, the model proved to address security challenges of the user virtual machine in IaaS environments by a security analysis.
