An Efficient User-to-User Authentication Scheme in Peer-to-Peer System

摘要：

In peer-to-peer environment,information is directly exchanged between nodes instead of forwarding by a central server,hence user-to-user authentication becomes a critical security issue in such environment.Existing solutions are based on public-key cryptosystem.The main concerns in a public-key cryptosystem include authenticity of the public key and lack of efficiency.A trusted third party is also involved in a public-key environment.This paper proposed an efficient one-way hash function based user-to-user authentication scheme with smart card in peer-to-peer system.In the proposed scheme,the system and peers do not have to maintain verification tables,and a trusted third party is not needed in the run time.The proposed scheme achieves mutual authentication at very low computational cost,but also provides good security strength.
