Towards comprehensive provable data possession in cloud computing

Abstract

To check the remote data integrity in cloud computing, we have proposed an efficient and full data dynamic provable data possession (PDP) scheme that uses a SN (serial number)-BN (block number) table to support data block update. In this article, we first analyze and test its performance in detail. The result shows that our scheme is efficient with low computation, storage, and communication costs. Then, we discuss how to extend the dynamic scheme to support other features, including public auditability, privacy preservation, fairness, and multiple-replica checking. After being extended, a comprehensive PDP scheme that has high efficiency and satisfies all main requirements is provided.
