P2P Routing Algorithm

[Abstract]
In P2P system, the message delivery function is needed to provide some services. But Considering operation of P2P system at an open network like Internet, the adversary can get a lot of nodes to attack easiry, due to the absence of authentication mechanism. When adversary nodes mediate messeage deliveries, message deliveries may be failed. And the failure of message deliveries invoke depression of system availability. To prevent such attack, secure routing algorithm, which improve the provability of successfull message deliveries, should be used. Then, the proposition of secure routing algorithm and the evaluation of security level for routing algorithm are important.
