The design and realization of security model for P2P network

Because JXTA has outstanding performance in support and secure part of the P2P network, so the network security model is designed and realized on JXTA platform. Classified by function implementation, security model can be divided into the peer group part and the node part. Through the JXTA platform, the peer group member part of creating module, authentication module, module, search method of node part get peer group membership module and intra group node communication protocol module and other parts can get the design and implementation of more efficiency. Through the interaction of each module, and create a safe environment which is relatively stable in the network.
