Cloud computing aims to enable end-users to easily create and use software without a need to worry about the technical implementations and nitty-gritty's such as the software's physical hosting location, hardware specifications, efficiency of data processing. It moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. This unique paradigm brings about many new security challenges, which have not been well understood. This paper studies the 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.
