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

Abstract

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.
