A Provable Data Possession Protocol in Cloud Storage Systems with Fault Tolerance

To maintain the availability and durability of data, data owners (DOs) usually store their mass data in remote cloud, which is namely called cloud storage. Cloud storage is one of the most important applications of cloud computing. Through the technique of cloud storage, DOs can enjoy the services and benefits of cloud computing. However, while bringing the convenience and efficiency, there must be some security issues like data corrupted threatened in the process of using cloud storage services. Through many provable data possession (PDP) protocols has been presented to deal with these threats, most of them don not consider the problem that how should the protocol proceed when the corrputed data was found. In this paper, we propose a provable data possession protocol with fault tolerance including corrupted data locating and recovering utilizing Cuckoo Filter and Reed-Solomon codes respectively. Finally, we illustrate the security and performance of the proposed schemes, which shows the practicability of the proposed protocol.
