A New P2P Identity Authentication Method Based on Zero-Knowledge Under Hybrid P2P Network

On the basis of analyzing the shortcomings of traditional authentication mechanism synthetically, the paper presents a new kind of P2P identity authentication model. In the new P2P Identity authentication model, it authenticates the identity of nodes by using a new Zero-Knowledge proof identification scheme which combines the advantage of RSA. Besides, during the process of validating nodes’ identity, CA (Center Authentication) doesn’t need to participate in. At last, Simulation results show that the new P2P identity authentication method can improve the safety of network effectively.
