In this paper proposed a problem of ensuring the integrity of data storage in Cloud Computing. In particular, the authors consider the task of allowing a Third Party Auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data stored in the cloud. The introduction of TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud are indeed intact, which can be important in achieving economies of scale for Cloud Computing. The support for data dynamics via the most general forms of data operation, the services in Cloud Computing are not limited to archive or backup data only.
