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 availability, data integrity, and data confidentiality. Security of data confidentiality consists of cryptographic approach and information-theoretic approach. For availability, integrity and information-theoretic confidentiality, network coding-based POR (Proof of Retrievability) schemes have been proposed to allow the client to check whether the data stored in the servers is available and intact. In this paper, we propose an extremely simple network coding-based POR, named S-POR (S-POR: Simple network coding-based Proof of Retrievability). The implementation shows that the S-POR incurs very low computation cost for both client-side and server-side. Due to its simplicity, the S-POR is the most practical network coding-based POR for a real system, to the best of our knowledge. |
