抄録(英) Since the amount of information is increasing quickly, the database owners have tendency to outsource their data to external service provider called Cloud Storage. In Cloud Storage, because the service provider may be not fully trustworthy, there are many challenges in securing the data stored on Cloud. We focus mainly on two challenges: data integrity and data availability. To ensure integrity and availability of such outsourced data, researchers proposed POR (Proof of Retrievability) scheme that enables servers on Cloud to demonstrate whether the client's data is retrievable or not. Although some schemes have been proposed based on POR, most of them neither minimize computation cost in repairing the corrupted data nor prevent against small data corruption attack. In this paper, we propose an efficient and secure POR scheme based on network coding approach that can reduce computation cost in repair phase when corruption is detected and Error-correcting code (ECC) approach that can protect against small data corruption.
