摘要：Cloud-based outsourced storage relieves the client’s weight for storage supervision and upholding byproviding a comparably low-cost, scalable, location-independent policy. However, the reality that clients no longer havephysical control of data indicates that they are facing a potentially formidable threat for missing or corrupted information.To keep away from the security threat, audit services are dangerous to ensure the integrity and accessibility of outsourcedinformation and to achieve digital forensics and reliability on cloud computing. Provable data control which is acryptographic method for verifying the integrity of information without retrieving it at an un-trusted server can be used torecognize audit services. In this paper, profiting from the interactive zero-knowledge proof scheme, we deal with theproduction of an interactive PDP protocol to avoid the fraudulence of prove and the leakage of verified information. Weverify that our construction holds these properties based on the calculation Diffie–Hellman statement and the rewind ableblack-box information extractor. We also suggest an efficient method with respect to probabilistic queries and interruptedverification to decrease the audit costs per confirmation and realize abnormal discovery timely. In addition, we present aresourceful method for selecting an most favourable parameter value to decrease computational overheads of cloud auditservices. Our investigational results demonstrate the usefulness of our approach.
