Third Party Public Auditing Scheme for Security in Cloud Storage

Abstract

By means of cloud storage, users can distantly store their data and enjoy the on-demand high-quality applications and services from a shared group of configurable computing resources, without the burden of local data storage and maintenance.However, the information that users no longer have physical ownership of the outsourced data makes the data integrity protection in cloud computing a difficult task, particularly for users with constrained computing resources.Moreover, users should be able to just use the cloud storage space as if it is local, without worrying about the need to verify its integrity.Thus, to enable public auditability for cloud storage is of serious importance so that users can rely on a third-party auditor (TPA) to verify the integrity of outsourced data and be worry free.To securely introduce a well-organized TPA, the auditing process should bring in no new vulnerabilities to user data privacy, and introduce no additional online burden to user.However; we propose a secure cloud storage system supporting privacy-preserving public auditing and monitoring.We additional would extend our result to enable the TPA to perform audits for multiple users simultaneously and efficiently, also integrity of data in cloud.Extensive security and performance analysis show the future schemes are provably secure and highly well-organized.Our beginning tryouts would be conducted on Amazon EC2 instance additional demonstrating the fast performance of the design.
