Abstract
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.

2.3 Security challenges of virtual machines in IaaS security domain Users’ virtual machines are their private property, just like the property stored in a safety deposit box in a bank, which cannot be accessed by any other person or authority
Summary
The application of cloud computing is becoming more and more popular. Cloud computing integrate separate information resources and supply on demand. Based on the trusted root, using the trust chain delivery mechanism, trusted computing technology implements integrity measurement to the local hardware and software layer by layer. Trusted computing technology gets rid of dependency on the central server for distributed nodes, directly through the TPM chip to build trust on the user’s machine, to create better scalability, higher reliability, availability, and enhanced security of distributed applications platform. In IaaS environment, the user virtual machine is a private property, the privacy protection is very important in the process of integrity measurement. We proposed a trusted measurement model based on dynamic policy and privacy protection in IaaS security domain that can implement the effective trust measurement and protect the privacy of user’s virtual machine.
