A cloud storage system consisting of a collection of storage server. In cloud, storing data in a third party causes serious concern on data confidentiality. The user stores the encrypted data in the multiple storage servers and with a key. The encryption scheme supports encoding operations in the encrypted message. Forwarding operation performs by the re-encryption key. Each storage server uses the re encryption key to re encrypt its word symbols. The user sends a request to key server for retrieve a message. The key server randomly chose the storage servers to get code codeword symbols and decrypted codeword symbols to get a message.
