A PROTECTED DECENTRALIZED ELIMINATION CODE FOR DISPERSED NETWORK STORAGE
Gundrati Santosh Kumar, L.Ravi Kumar, G.Charles Babu
In recent years, many services are provided on the Internet such that users can use them from anywhere at any time as high-speed networks and ubiquitous Internet Cloud computing treats the resources on the Internet as a unified entity. There have been numerous proposals of storing data over storage servers. One way to make available data robustness is to replicate a message such that each storage server stores a copy of the message and it is very tough because the message can be retrieved as long as one storage server survives. An additional way is to determine a message of k symbols into a codeword of n symbols by elimination coding. In a proxy re-encryption system, a proxy server can convey a cipher text under a public key to a new one under another public key by means of the re-encryption key. The threshold proxy re-encryption method supports encoding, forwarding, and partial decryption functions in a dispersed way. The rigid integration of encoding, encryption, and forwarding constructs the storage system resourcefully meet the needs of data robustness, data secrecy, and data forwarding. The distributed storage system not only supports protected and vigorous data storage and retrieval, but also allows a user forward his information in the storage servers to an additional user devoid of retrieving the data back.
