we proposed a general model of Peer-to-Peer based Cloud Storage system named MingCloud

and constructed a prototype system based on Kademlia algorithm.Highlighting the system security and reliability of data

search and other cloud storage services.Results from our simulation experiment show that MingCloud system has high availability and performance

which can be actually applied to the Internet dynamic and open environment after improving and optimizing

and to provide higher quality of cloud storage service.
