摘要:The integrity of data is ensured by the technique called Provable Data Possession (PDP) in storage outsourcing. In our paper, wedeal with the construction of PDP scheme which is efficient for distributed cloud storage. This supports the scalability of service and datamigration where we consider that the clients’ data is stored and maintained by the multiple cloud service providers. We introduced CooperativePDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy. The security of our scheme is provedbased on multi-prover zero-knowledge proof system. This system satisfies the properties like completeness, knowledge soundness, and zeroknowledge.Besides we study the performance optimization mechanisms for our scheme, and particularly we present a method, to minimizethe computation costs of clients and storage service providers, which is efficient for selecting optimal parameter values. We show with ourexperiments that our solution introduces lower computation and communication overheads in comparison with non-cooperative approaches
