Abstract :
P2P network is short of authentication, so the CPK (Combined Public Key) authentication mechanism and DHT (Distributed Hash Table) algorithm in P2P network are researched, and CPK authentication is used in structure P2P network for its security. At point, the series-Hash method combines both DHT algorithm of structure P2P network and peers´ authentication. Then base on cluster partition P2P network, a multi-field key manage method is brought forward, which combined public key and cluster extend public key. At last, security problems of this authentication system are discussed.
