Abstract— With the continuous growth in the cloud based applications and storage requirements on cloud, many commercial cloud based storage service providers are making the market more competitive with the advanced technologies and reduced cost. The advancement in technologies and high demand for fault tolerant storage solutions most of the cloud based commercial storage service providers are now equipped with Erasure based Reed – Solomon fault tolerance mechanism. However the additional cost for replication is still an overhead for service providers and customers. We propose a threshold proxy re-encryption scheme and integrate it with a decentralized erasure code such that a secure distributed storage system is formulated. The distributed storage system not only supports secure and robust data storage and retrieval, but also lets a user forward his data in the storage servers to another user without retrieving the data back. The main technical contribution is that the proxy re-encryption scheme supports encoding operations over encrypted messages as well as forwarding operations over encoded and encrypted messages. Our method fully integrates encrypting, encoding, and forwarding. We analyse and suggest suitable parameters for the number of copies of a message dispatched to storage servers and the number of storage servers queried by a key server. These parameters allow more flexible adjustment between the number of storage servers and robustness.
