摘要：A storage system consists of a collection of storage servers for the user data to be stored in the third party storage system having thousands of storage servers, but it causes serious concern over data confidentiality.Encryption schemes protect data confidentiality, but storage servers cannot directly forward a user's data to another user. In this paper, a threshold alternate re- encryption scheme is proposed for addressing the problem of forwarding data to another, by storage servers directly under the command of data owner. This method fully integrates encryp ting, encoding and forwarding. The distributed storage system not only supports protected 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 parameters regarding the number of copies of a message dispatched to storage servers and number of storage servers is analysed
