A new remote data integrity checking scheme for cloud storage

Cloud storage services enable user to enjoy high-capacity and high-quality storage with less overhead, but it also brings many potential threats, for example, data integrality, data availability and so on. In this paper, we propose a new remote integrality and availability checking scheme for cloud storage. This new scheme can check mass file\u27s integrality and availability with less storage, computation and communication resource. The new scheme also supports data dynamic update, public verifiability and privacy preserving
