A peer mutual authentication method on super peer based peer-to-peer network

In this paper, we suggest a peer authentication method that authorizes the peer which requests the other peer to use a service of it on super peer based peer-to-peer (P2P) network architecture. The proposed peer authentication method, at which one-time session-keys, public key certificate (PKC) and ticket authentication mechanism are applied, enables each peer to perform strong mutual authentication in P2P network. The peer mutual authentication is performed by getting authentication ticket, submitting it to other peer and verification it by the peer. Also, the lifetime of each ticket can be controlled by the peer providing services according to each service.
