The Research And Design Of Remote Attestation Based On Cloud Computing Environment

Along with the development of information technology, the computer world appearedmore and more novel and practical technologies, one of which is cloud computingtechnology. Cloud computing applies a large number of the virtualization technology, whichwill cause two problems: first, the introduction of virtualization technology produces somespecific security risks, and the major difference between cloud computing and the traditionalsafety is how to solve the security problem of virtualization aspects; Second, cloudcomputing stands for a new transformation of service methods. For the server, network andclient security needs are changed, the traditional security means already cannot adapt to thesecurity needs for cloud computing. At present, in solving cloud computing security issues, alot of methods and ideas has sprung up. Applying the credible technique to solve the securityproblem of cloud computing and providing cloud service in a reliable way has been a hotspotin cloud security research field.This topic was based on the background of rapid development of cloud computing andtrusted computing technology, and research for applying the trusted computing remoteproof technology into the cloud computing and combining with virtualization technology inorder to solve the cloud computing IaaS environment between virtual domain securityproblems. This paper studies the trust defects between virtual domain under cloudcomputing IaaS environment, then in-depth research a kind of IaaS platform-XCP platform.Based on the problem of trust defects, we research the trusted computing relatedtechnologies, especially the remote proof technology. In the virtual domain based on the XCPplatform, we complete the set up and integration of vTPM and trusted computingcomponents (IMA, TDDL, TSS), which can lay the foundation of software and hardware forrealizing reliable remote proof in XCP platform. Then, we design and realize remoteattestation scheme between different virtual domain in the XCP platform, and solve thebinary remote proof for the presence of version update problem. The main work is asfollows:Research the cloud computing of IaaS environment characteristics and securityproblem;Research the relevant technology of the trusted computing,Research the mainstream remote proof technology; Research the vTPM and trusted components (IMA, TDDL, TSS) structures andintegration;Design and realized a kind of identity authentication scheme based on vTPM;Design and realize the cloud computing IaaS environment of remote proof plan;Design the binary remote proof version update scheme.
