A Novel Application for Integrity Verification in Multi-Cloud Storage by using Provable data possession
Chandra Sekhar Golagana · 2013
Now a days for every data transfer between any sites we are using cloud data transfer instead of distributed data transfer. so we must concentrate on security. Provable data possession (PDP) is a technique which used for integrity of data in storage outsourcing. In this paper,we present a schema for the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and datamigration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients’ data. We present a cooperative PDP (CPDP) scheme based on verifiable response using cryptographic and hash index hierarchy. The security of our scheme based on multi-prover, zero-knowledge proof system, which can satisfy completeness,knowledge soundness, and zero-knowledge properties. We are using AES method for cryptographic. Our experiments show that our solution introduces lower computation and communicationoverheads in comparison with non-cooperative approaches.
