Abstract: Cloud storage is a model of networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Organizations cite data confidentiality as their serious concern for cloud computing, with uncrypted data stored on third party’s cloud system, The functionality of the storage system is limited when general encryption schemes are used for data confidentiality. With this consideration, we propose a new threshold proxy re-encryption scheme to form a secure distributed storage system. This distributed storage system also lets a user forward his data in the storage servers to another user without retrieving the data back 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 reencryption scheme supports encoding operations over encrypted messages as well as forwarding operations over encoded and encrypted messages.
Keywords: Distributed storage system, encoding, proxy re-encryption, uncrypted data.
