A wew remote data integrity checking scheme for cloud storage with privacy preserving

Cloud storage services enable users to enjoy high-capacity and high-quality storage with less overhead. However, the fact that users no longer have physical possession of the data makes the data integrity protection in cloud storage a very challenging and formidable task. In this paper, we propose a new remote integrality checking scheme for cloud storage that integrate correct checking, dynamic update and privacy preserving. The security and performance analysis shows that this new scheme is provably secure, and can check mass remote file´s integrality with constant storage and communication resource for cloud storage users.
