Abstract: Cloud storage is the most demanded feature of cloud computing to provide outsourced data on-demand. However, users are in a dilemma to trust over the cloud service providers regarding whether privacy is preserved, integrity is maintained, and security is guaranteed, towards the outsourced data. Therefore, it requires developing an efficient auditing technique to provide confidence upon the data present in cloud storage. We propose a peer-to-peer (P2P) public auditing scheme to audit outsourced data using a dynamic-hash-table (DHT) to strengthen the users' trust, and availability over the data. Each DHT maintains the information of outsourced data, which helps the auditors to provide safety and integrity while auditing them. Moreover, these auditors are organised into a structured P2P to accelerate the auditing along with the auditor's availability. Thus, the proposed scheme overcomes from a single point of failure, and found to be computational less as compared with the existing methods.
