A Data Integrity Verification Scheme with Secure Deduplication in Smart Grid Cloud Storage

Abstract

In order to solve the problem of data deduplication and data integrity in smart grid cloud storage, a data integrity verification scheme which can support security deduplication is proposed in the context of smart grid cloud storage. This scheme refers to an efficient and safe deduplication method based on the bloom filter, realizes the quick verification of the user s hash value and initialization value. In addition, the secure deduplication method is combined with S—PDP integrity verification mechanism, data segmentation and random sampling strategy, to realize the security deduplication and integrity verification of smart grid clients. By using erasure correction code, users can repair the damaged data. The analysis results show that this scheme can effectively reduce the computing cost and communication cost while ensuring that the cloud storage data of smart grid can be secure deduplicated and integrity verified.
