Abstract: -Cloud Computing has been envision as the next-generation structural design of IT Enterprise. It moves the purpose software and databases to the centralized large data centers, where the organization of the data and services may not be fully reliable. This unique paradigm brings about many new protection challenges, which have not been well implicit. This work studies the problem of ensuring the integrity of data storage in Cloud Computing. In particular, we consider the task of allowing a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data store in the cloud. The beginning of TPA eliminates the association of client through the auditing of whether his information stored in the cloud is indeed intact, which can be significant in achieving economies of scale for Cloud Computing. The support for data dynamics via the most universal forms of data operation, such as block modi?cation, addition and removal, is also a signi?cant step toward expediency, since services in Cloud Computing are not incomplete to archive or backup data only. While prior works on ensuring remote data reliability often lacks the support of either public veri?ability or dynamic data functions, this paper achieves both. We ?rst identify the di?culties and potential protection problems of direct extension with fully dynamic data updates from prior works and then show how to construct an elegant verifcation method for seamless integration of these two salient features in our protocol design.
