摘要

The Cloud storage service allows data owner to outsource data storage at the Cloud which introduces security challenges requiring an auditor to check the integrity of stored data. This paper proposes an efficient auditing scheme for checking the integrity of dynamic data outsourced at un-trusted Cloud storage. This scheme based on the Boneh and Boyen signature enables a third-party auditor to audit the client's data while preserving the privacy of the data. The scheme is found to be secure in the standard model. Complexity analysis shows the proposed scheme is efficient when compared to existing schemes.
