Abstract
We introduce a model for provable data possession (PDP) which allows a client that has stored data at an untrusted server to verify that the server possesses the original data without retrieving it. In a previous work, Ateniese et al. proposed a remote data integrity checking protocol that supports data partial dynamics. In this paper, we present a new remote data possession checking protocol which allows an unlimited number of file integrity verifications and efficiently supports dynamic operations, such as data modification, deletion, insertion and append. The proposed protocol supports public verifiability. In addition, the proposed protocol does not leak any private information to third-party verifiers. Through a specific analysis, we show the correctness and security of the protocol. After that, we demonstrate the proposed protocol has a good performance.

Summary
Many works focus on providing remote data integrity checking protocols. Because storing data in the cloud has become a trend and an increasing number of clients store their important data in remote servers in the cloud, without leaving a copy in their local computers. Using a remote data integrity checking protocol, the client might be able to periodically verify that whether the data stored on the server side is complete. Ateniese et al [2] first defined the notion of PDP, which allows a client to verify the integrity of its data stored at an un-trusted server without retrieving the entire file. Their scheme is designed for static data and used public key-based homomorphic tags for auditing the data file. After that Wei Xu et al [8] proposed a remote storage integrity checking protocol based on homomorphic hash function, but the disadvantage of this protocol is losing feature of public verifiability.
