With the advent of cloud computing era, cloud security has become one of the core issues to focus on, especially the security risks caused by virtualization. This research combined with the trusted computing and cloud computing security, establish a credible system by using the authentication center (CA) and trusted platform module (TPM). The study take the CA as the root of trust cloud computing platform. The server uses the TPM module through the operations of acquisition, registration, certification for the certification, and the operations of new construction, launch, running, transfer and maintenance for the virtual machine (VM), we can design and implement the trusted ensure of the security. The study designed the trusted module which take the TPM chip as the core, the develop the VM complete credible system and measurement algorithm. VM authentication mechanism and the access user authentication mechanism of VM.
