Effective and Flexible Scheme for Secure Storage in Cloud Computing
The success of cloud computing has attracted attention for cost effective IT services with many signs for continuing spread out if not dominating in the coming years is reported recently. IT services in Cloud Computing face the overwhelming challenges to ensure the proper physical, logical and personnel security controls, especially when considering the fact that cloud computing moves the application software and databases to the large data centers. This work 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.
