The Improvement Of Virtual Machine

Trusted Platform ; cloud security

With cloud computing booming, cloud security arises. The distrust between cloud providers and cloud users greatly influenced the development of cloud computing. While trusted cloud platform has been put forward , the cloud security issues were preliminarily solved. In the basic model , the trusted third coordinator authenticate the built-in trusted chip TPM and then manage the active list of trusted services and participate in virtual machine (VM) migration of dynamic and virtual machine starting. Trusted chip can ensure the security of virtual machines running in a cloud computing environment. This paper will be based on the TCCP model to improve it, using the active validation method to replace the passive validation, the node transitions can reduce the time when establishing trust in a certain extent. Meanwhile, By using two-way authentication instead of one-way authentication, the platform of the node and PCA have played an important role in the real-time supervision and increase the security of the platform.
