Overview of research on trusted attestation technology of cloud virtualization platform

Abstract

With the rapid development of cloud computing， the security issues of cloud platforms have also attracted much attention.Trusted computing is an essential supporting technology in the cloud computing security system.Trusted attestation is an important feature in trusted computing.The use of trusted attestation technology verifies whether the cloud virtualization platform is trustworthy， thereby providing a foundation for ensuring the security of the cloud platform.Now based on the definition of trusted attestation， the research progress of key technologies such as the root of trust virtualization， platform identity authentication， platform status certification， and trusted attestation framework for virtual machines were systematically sorted out， typical schemes were analyzed and compared.Furthermore， the limitations of existing work were discussed.Finally， the future research trend of this area were pointed out.
