摘要：Cloud storage service is collection of storage servers, its provide storage service on internet. In third party cloud server stored data may cause serious concern. There is some limit of functionality of storage service as to save data confidentially use encryption scheme but few operations are supported over the encrypted data. Distributed storage system which have no centralized author their using is very challenging. We define proxy re-encryption scheme with erasure code help for secure data. To store data secularly and for easily retrieval distributed storage system support efficiently and the user can forward data to another user without retrieving back. Proxy encryption scheme support encoding operation over encrypted massage and it was main technical operation as well as forwarding data as encrypted massage. We suggest to determine copies of massage which is send to the storage server, distributed storage service stored data on storage server and key server which is work independently. These define parameters allow more flexibility adjustment between number of storage server and robustness
