For routing and lookup efficiency, DHT-based overlay network has been developed. The representative DHT-based overlay networks are Kad, Chord, Pastry and CAN. And Several applications such as file sharing, distributed storage system have been developed on the DHT-baed overlay network. But there exist several security attacks on the DHT-based overlay network: Peer ID attack, Attacks on message routing, Rapid join/leave attack, DoS arrack and so on. In this paper, we propose secure routing mechanism against message routing attacks for DHT-based overlay network. The proposed mechanism ensures that when a normal peer sends a lookup messages using a key, the messages delivered to the peer which is owner of the key with very high probability.
