Secure Geographic Based Routing Protocol of Aeronautical Ad Hoc Networks

Aiming at the problem that routing security for Geographic information cannot be guaranteed, a Secure Geographic based Routing Protocol of Aeronautical Ad hoc Networks (S-GRP) is proposed. Through identity-based public key cryptosystem, it makes authentication for neighbor node and establish a shared secret in the neighbor discovery phase, and then makes signcryption for data in the data forwarding phase. When in the next hop selection, it makes an integrated assessment for node location-speed factor and trust factor, selecting the optimal next hop. Security analysis and performance analysis for S-GPR show that the algorithm is effective and feasible.
