| Abstract(in English) | Cloud storage has been gaining in popularity as an on-line service for archiving or backup. However, due to the data outsourcing, cloud storage also introduces new security challenges, which require a data audit and data repair service to ensure data availability and data integrity in the cloud. In this paper, we present the design of a network-coding-based Proof Of Retrievability (POR) scheme, which achieves a lightweight data auditing and data repairing. In particular, we support ``direct repair'' mechanism in which the client can be free from the data repair process. Simultaneously, we also support the task of allowing a third party auditor (TPA), on behalf of the client, to verify the availability and integrity of the data stored in the cloud servers without the need of an asymmetric-key setting. The client is thus also free from the data audit process. |
