Abstract: Cloud storage is a storage service offered by Cloud Service Provider (CSP) to data client, where the data is outsourced to distributed servers in cloud, while data client has to pay upon usage. As integrity and availability are the pre-conditions for the existence of a cloud storage system, Proof of Retrievability (PoR) is introduced to cloud storage. Recently, Slepian-Wolf Based Proof of Retrievability (SW-PoR) was introduced that provides costefficient and time consistent exact repair mechanism for erroneous outsourced data. However, the encoding process of SW-POR requires a certain amount of computation time, which considerably long compared to conventional storage method involving replication. Hence, this paper proposed an extension work to SW-PoR, named Partial Binary Encoding for SW-PoR (PBE-SW-PoR) to address the limitation. Simulation was conducted to evaluate the performance of the proposed work by means of comparison to the original SW-PoR scheme in term of computation time. In our simulation, result obtained has shown a significant performance improvement in computation time for PBE-SW-PoR compared to original SW-PoR.
