Dynamic centered group key management for unmanned aerial vehicle networks with multibeam concurrent transmissions
Qian Mao, Fei Hu, Ji Qi · 2017
Current key management protocols involve high computational complexity and large-scale broadcast, which are inapplicable for Unmanned Aerial Vehicle (UAV) networks. This paper proposes a novel group key management protocol, which avoids high computation cost by employing a secret sharing algorithm based on Chinese Remainder Theory. Furthermore, the proposed scheme dynamically chooses the information source as the key distribution center and piggybacks the key management messages onto routing communications, which are suitable for UAV networks and build secure sessions in an efficient manner.
