Disruption-Tolerant Networks (DTNs) deliver data to the collection of intermittently connected nodes. In traditional networks, malicious nodes within a DTN may try to attempt a data destruction or delay in transmit the data to its destination. In this paper, the flooding attack is focused and provides possible solutions for secure communication. Many existing algorithms for secure routing require security mechanisms like Public Key Infrastructure (PKI), which is difficult to deploy in a DTN. This paper proposes a secure communication model to transmit the packet from source to destination with PKI.
