Securing a Janus-Based Flooding Routing Protocol for Underwater Acoustic Networks

In this paper, a secure-capable multi-user network protocol proposed which uses the Janus standard in a hybrid cellular/ad hoc topology. In a cellular topology, a self-organized ad hoc mode employing a flooding routing protocol is utilized as a backup when the local gateway-sink node is unreachable. Employing an optimized flooding routing protocol to relay packets in an underwater network increases the packet delivery ratio, and decreases latency. This protocol is applied to a 40node network in an area of 100 square kilometers. For the scenario defined, each packet is forwarded 71 times for it to be received by the destination. This is 29% less than for the common flooding routing protocol, which means notable energy savings in the network. However, adopting a collaborative distributed architecture with multi-hop relaying nodes enhances security threats over the network. This is particularly true when external relay nodes collaborate in the routing mechanism. We investigate vulnerabilities of the Janus-based flooding routing protocol in a self-organized ad hoc topology. We suggest the Elliptic-curve Diffie Hellman (ECDH) key agreement and applying a light weight data encryption on the application layer to protect the communications between the source and destination nodes against eavesdropping and data tampering. As will be demonstrated, applying a security suite on the protocol will impose considerable overhead on the network, since it requires additional handshaking for key exchange, as well as the transmission of large-sized encrypted packets.
