摘要：Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. This work studies theproblem of ensuring the reliability of data storage in Cloud Computing. In particular, we consider the task of allowing aThird party assessor, on behalf of the cloud client, to verify the reliability of the dynamic data stored in the cloud. Theintroduction of Third party assessor eliminates the involvement of the client through the assessing of whether his datastored in the cloud is indeed together, which can be important in achieving economies of scale for Cloud Computing. Thesupport for data dynamics via the most general forms of data operation, such as block modification, insertion and deletion,is also a significant step toward practicality, since services in Cloud Computing are not limited to archive or backup dataonly.While prior works on ensure isolated data reliability often lacks the support of either public review capability ordynamic data operations, this work achieves both. We first identify the difficulties and possible protection problems ofthrough extensions with fully dynamic data updates from prior works and then show how to construct the seamlesscombination of these two most important features in our procedure design.
