SUPER PEER BASED PEER-TO-PEER NETWORK SYSTEM AND PEER AUTHENTICATION METHOD THEREFOR

摘要

A super peer based P2P network system and a peer authentication method for the same are provided to limit a service use time according to each user by using a valid time of a ticket. A peer A(110) transmits a connection request message to a super peer A(130)(S310). The super peer A transmits an authentication information request message to the peer A(S320). The peer A provides interface to user(S325). The peer A transmits an authentication information message to the super peer A(S330). The super peer A transmits an authentication request message to an authentication server(150)(S335). The authentication server performs authentication about a corresponding user and the corresponding peer(S340). The authentication server generates a disposable session key(S345). The authentication server transmits an authentication success message and the disposable session key to the super peer A(S350). The super peer A adds the peer A to a connection allowable peer list(S355). The super peer A transmits a connection allowable message to the peer A(S360).
