Disruption Tolerant Networks (DTNs) utilize the quality of nodes and also the opportunist contacts among node for information communications. Because of the limitation in network resources such as contact opportunity and buffer space, DTNs are at risk to flood attacks within which attackers send as several packets or packet replicas as possible to the network, so as to exhaust or overuse the restricted network resources. In this paper, there is a rate limiting to defend against flood attacks in DTNs, such that every node has a limit over the amount of packets that it will generate in every time interval and a limit over the amount of replicas that it will generate for every packet.
