Cloud computing aims to enable end-users to easily create and use software without a need to worry about the technical implementations and nitty-gritties such as the software's physical hosting location, hardware specifications, efficiency of data processing.Recently many works focus on providing data dynamics and/or public verifiability to the protocols checking the remote integrity with the help of third party verifiers.In this paper, Seb´e et al.'s protocol is adapted to support public verifiability and data dynamics without the help of a third party auditor.This design allows users to audit the cloud storage with very lightweight communication and computation cost.In addition, the auditing result not only ensures strong cloud storage correctness guarantee, but also simultaneously achieves fast data error localization, i.e., the identification of misbehaving server.The design further supports secure and efficient dynamic operations on outsourced data, including block modification, deletion, and append.Through a formal analysis, the correctness and security of the protocol is shown.The proposed scheme is highly efficient and resilient against the malicious data modification attack, server clouding attacks and failure.
