Abstract:

For the application of cloud storage in the big data center, a user no longer possesses his files in his local depository. Thus, he is concerned about the security of the stored files. For data robustness, there are two concerns: service failure, and service corruption. In this paper, we propose an integrity check scheme for their system to enhance data robustness against storage server corruption, with which their storage system in the big data center can deal with not only the problem of storage server failure, but also the problem of storage server corruption. Furthermore, we adopt homomorphic integrity tags such that new integrity tags can be computed from old integrity tags by storage servers without involvement of the user's secret key or backup servers. In conclusion, we prove the security of our integrity check scheme formally.

Key words: integrity check scheme, cloud storage, big data center, data robustness, security
