A cloud storage system provides long-term storage services over the Internet and consisting of a collection of storage servers. Storing data in a third party's cloud system causes serious concern over data confidentiality. Data confidentiality can be provided in the general encryption techniques; however, there is limited no. of functionalities. Constructing a secure storage system that supports multiple functions is challenging when the storage system is distributed and has no central authority. Previously, a threshold proxy re-encryption scheme and integrate it with a decentralized erasure code such that a secure distributed storage system is formulated.
