Summary:
This paper proposes an efficient batch auditing technique to enhance the security of cloud computing systems. Through this technique, the cloud server computes proofs of audited files on the basis of the proposed auditing tree and sends them to a third-party auditor (TPA). The server uses the auditing tree to temporarily store the proofs during the batch auditing process. If an error message accompanies the batch auditing results, then the cloud server retrieves and sends auditing information from the auditing tree to the TPA without regenerating the auditing information. The TPA quickly and efficiently identifies erroneous files by using secondary information from the cloud server. The communication and computing costs of the proposed technique represent an improvement over similar schemes.
