In order to address the remote attestation issues in trusted computing

a new remote attestation framework which combines virtual machine and policy was proposed and implemented.This framework created a trusted virtual machine to provide a trusted executing environment for applications in the user platform.With the framework

the service provider could make and distribute flexible and fine-grained policies and the client could enforce these policies.So the behaviors of platform could be conformed to the expectation of the service provider.Analysis on the framework and experimental results showed that this architecture could accommodate more application in an open manner.And this framework can embody behavior’s conformance and possessed the properties such as real-time

dynamism and flexibility.
