Cloud computing has been envisioned as the on-demand self-service, ubiquitous network access, location independent resource pooling, rapid resource elasticity, usage-based pricing and transference of risk. Today, technical research works focus on Remote data possession Checking protocols permit to check that a remote server can access an uncorrupted file with the help of third party verifiers. In this paper, Seb´e et al.’s protocol is adapted to support efficient remote data possession checking in critical information infrastructure 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 remote 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.
