Abstract
In this paper, we propose a cloud storage scheme which simultaneously achieves security, reliability, and deduplication. Our scheme blends convergent encryption and perfect secret sharing method to achieve confidentiality of data and encryption keys. It also achieves fault tolerance by dispersing data to multiple storage servers using Reed-Solomon erasure code. We use Merkle hash tree to authenticate users by verifying Proof of Ownership (PoW) of data for carrying out secure deduplication. Both theoretical security analysis and experimental evaluation demonstrate that our scheme is provably secure and incurs only a small overhead compared to the existing systems.
