Identity-Based Distributed Provable Data Possession in Multicloud Storage

PROJECT TITLE :

Identity-Based Distributed Provable Data Possession in Multicloud Storage

ABSTRACT:

Remote information integrity checking is of crucial importance in cloud storage. It will make the shoppers verify whether or not their outsourced information is kept intact without downloading the full information. In some application scenarios, the clients need to store their information on multicloud servers. At the identical time, the integrity checking protocol should be economical so as to save lots of the verifier's price. From the two points, we have a tendency to propose a completely unique remote data integrity checking model: ID-DPDP (identity-based mostly distributed provable data possession) in multicloud storage. The formal system model and security model are given. Based on the bilinear pairings, a concrete ID-DPDP protocol is meant. The proposed ID-DPDP protocol is provably secure below the hardness assumption of the quality CDH (computational Diffie-Hellman) downside. In addition to the structural advantage of elimination of certificate management, our ID-DPDP protocol is also efficient and flexible. Primarily based on the client's authorization, the proposed ID-DPDP protocol will notice private verification, delegated verification, and public verification.
