摘要：Cloud computing is the delivery of computing and storage capacity as a service to a community of endrecipients. Cloud computing entrusts services with a user's data, software and computation over a network. It is an emerging computing model in which resources of the computing communications are provided as services over the internet. Cloud storage enables users to remotely store their data and enjoy the ondemand high quality cloud applications without the burden of local hardware and software management. The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost. 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. Considering the cloud data are dynamic in nature, the proposed design further supports secure and efficient dynamic operations on outsourced data, including block modification, deletion, and append. Analysis shows the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server scheming attacks. It propose some services for data security and access control when users outsource sensitive data for sharing on cloud servers.
