SEER4US, Secured Energy Efficient Routing for UAV Swarms

Abstract

This article introduces SEER4US a secured routing protocol designed for UAV swarm networks. SEER4US is the first protocol providing integrity of routing messages and authentication of their sender with low energy consumption for battery preservation. SEER4US prevents the UAV swarms from usual routing attacks enabled when routing messages are modified or replayed by nodes external to the swarm. SEER4US is an extension of the pro-active routing protocol OLSR designed for mobile ad-hoc networks. SEER4US is also inspired from TESLA, a protocol designed for stream signature allowing authentication of stream messages sender. After specifying SEER4US, we evaluate here the energy requirements of this protocol and we show that the use of lightweight cryptography allows a significant energy saving compared to traditional cryptographic schemes.
