| 抄録: | Cloud Computing is a service by which clients can outsource their data to reduce the burdens of data storage and maintenance. However, cloud providers are untrustworthy, which therefore introduce several security challenges: data integrity, data availability and data confidentiality. Since integrity and availability are prerequisite conditions for the existence of a system, researchers focus on these before confidentiality. To ensure integrity and availability, network coding-based POR (Proof of Retrievability) schemes have been proposed to enable the client to check whether the distributed data stored in the cloud servers is intact or not. However, most existing schemes have not achieved exact-repair feature and efficiency. In this paper, we propose a new POR scheme named SW-POR (Slepian-Wolfbased Proof of Retrievability) to address these gaps. Our scheme supports exact repair in which the repaired data is the same as the original corrupted data. Our scheme also can reduce the storage, computation, communication overheads and the size of a coded block. We proposed SW-POR based on Slepian-Wolf data compression code. We prove our security using entropy theory and implement SW-POR to show the costs. |
