摘要：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. Encryptio n 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 distrib uted 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
