Abstract


With the rapid development of the computer and the Internet , the birth of many new technologies and applications , and also resulted in a large number of computing resources , storage resources , including idle and wasted . Peer-to-peer network , the DHT network development , and provides an effective integration of the technical means of the edge of the network resources . By building distributed secure storage system based on collaboration , like access to the machine 's resources transparently access storage resources on the network to be able to maximize the use of the computing power of the human society , era needs . In -depth study of the the DHT classic model based on the prototype of Chord improvements proposed and designed a DHT application model HSChord . Be applied to the paper design model HSChord HSCSS system , revised and improved routing lookup algorithm , the concepts of classification and security . The system to ease the structured P2P networks are vulnerable to malicious node attack , such as : Witch attacks and Byzantine attacks ; core node node ID allocation and signature enhance the robustness of the system ; in one million O ( 1 ) class lookup junction scale . On the other hand , in order to solve the inefficiencies in the near logical P2P overlay network node data migration and replication , Nankai assigned nearly 16,384 public IP address for the sample test and try a partial solution to the node topology awareness consistency problem; symmetric cryptography , public key cryptography and PKI system , smart card - based applications , offline CA mechanism for structured overlay network of the system design ; through research and improved Erasure coding techniques , file redundancy coding. In order to verify the theory study , based on Visual C development platform , implemented in the Windows XP operating system , a distributed security cooperative storage systems validation prototype HSCSS . Dedicated , high-speed design philosophy with the existing network storage systems , HSCSS positioned in the level of \, high reliability , disaster recovery, distributed storage system .
