Robust secure data auditing in cloud computing

Cloud Storage allows users to store their data and use the cloud applications without the need of local hardware and software resources. Cloud Storage service possess many security risks against storage exactness. This paper presents a flexible distributed storage integrity auditing mechanism to achieve fast localization of data error with low complexity. The proposed design allows users to audit their data and it achieves dynamic data support to ensure the correctness and availability of user's data in cloud. i.e., it efficiently supports block modification, deletion, append.
