Research And Implementation Of The Trust Mechanism In Virtual Trusted Cloud Computing Platform

Cloud Computing Model provides the IT service which can meet people's needs with a flexible,cost-effective and reliable way for many small or medium enterprises and individual.However,even if the Cloud Computing provides the good quality service,as users,they have to face the worry about the data and applications which be trusteed and can not obtain their authorities.For the most Cloud Computing provider,they rarely publish the platform situation of running for users.So it will bring the crisis of trust between users and providers.And this crisis is a big block in the way of developing the Cloud Computing.With these problems of security trusted aspect.,this thesis will give some solution in cloud security study and research.Thesis will introduce some knowledge and technology about these topic and work in the trusted Cloud Computing,and then design and implement the environment of Cloud Computing Platform using Trusted Platform Model(TPM)which be virtualized.The whole of Cloud Computing utilizing the virtualization abstraction mechanism,makes the single physical machine can run multiple virtual systems.In the virtual environment,using the trusted computing technology,which was defined by Trusted Computing Group(TCG)that can be implemented by the physical chip called TPM,It can build the trusted mechanism in the Cloud Computing Platform.In this thesis,the research process is divided into two phases.In the first part,I will use the virtualization to virtualize the TPM to Guest OS.The way of virtualization is para virtualization and it can create a trust chain to complete the trusted mechanism.The second part is using the open-source cloud computing platform to finish the trusted mechanism.It will have the trust attestation to the single physical node.At the end of this thesis,there is the test for this environment of trusted cloud computing.The result also shows that in the cloud computing platform,it can establish a complete chain of trusted and to a single physical system node,the start consuming impact less.In summary,this study design for cloud computing security has some practical significance.
