However, when there are large amount of users try to access the files, the server will cost much more bandwidth and decrease the transfer efficiency, users have to wait much more time to download the files. When server was intruded and exposed all the files. We propose a Secure Information Distribution System based on Trusted P2P, the user will have to pass the authentication to publish and download files. In our system, we use a number of Block Storage Servers (BSSs) with BSS Agents to deploy a Distribution File Block Storage Server. The BSS Agent will be constructed as Trusted P2P network and support file space for authenticated information publishers to store their files. Our System will divide the file into several blocks and each block will be backup on a number of different BSS to supply the Fault Tolerance property. According to the file divide, distribution, backup and merge, our system will achieve the file backup, decrease the traffic flow and solve the problem when single BSS Agent was intruded and expose all the files. The BSS Agent will use the Chord to build the P2P network. When BSS Agent try to transfer block to other BSS Agents, they will arrange a dynamic group and share a one-time group key to protect the secrecy of block.
