Abstract

Integrity verification can effectively protect cloud data. Currently, users entrust third-party auditors to verify the integrity of their outsourced data. Unfortunately, multiple auditors participate in the integrity verification, which increases the risk of data privacy disclosure. Therefore, more users expect a specific verifier to check the files in cloud storage. We proposed a scheme with a designated verifier, which can effectively protect data privacy when auditing. In the process oey generate tags. In the evidence generation, bilinear results of data blocks and tags are directly calculated to realize privacyf tags generation, we utilize the designated auditor public k protection. Based on the computational Diffie– Hellman assumption in the Bilinear Maps, we prove the security for our scheme.
