Cloud Storage System has a collection of storage servers provides long-standing storage services over the internet. Data privacy becomes a major concern in cloud storage system because user stores his data in third party cloud system. Encryption schemes available for data privacy but it limit the number of functions done in storage system. Building a secure storage system that supports multiple functions is tough when the storage system is distributed and has no central authority. A new idea is proposed proxy re-encryption scheme for decentralizes erasure code for defending the distributed system. 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.
