A Novel Privacy-Preserving Public Auditing For Secure Cloud Storage
Using cloud storage, users can remotely store data and enjoy the on-demand high-quality applications and services from a shared pool of configurable computing resources, without the requirement of local data storage and maintenance. Though the users no longer have physical possession of the outsourced data makes the data integrity protection in cloud computing a challenging task, especially for users with constrained computing resources. In addition users should be able to just use the cloud storage as if it is local, without having any concern about the need to verify its integrity. Thereby, the public audit ability of cloud storage can be of vital importance so that the users can infest to a third-party auditor (TPA) to check the integrity of outsourced data and be trouble free. To securely introduce an effective TPA, the auditing process should fetch no new vulnerabilities toward user data privacy, and introduce no additional on-line difficulty to user.
