Enhancing Security and Privacy in Vehicular Networks

Autonomous vehicles are expected to avoid accidents and alleviate traffic congestions by communicating with each other and the infrastructure. The communication network needs to provide security, privacy, and availability. The Dedicated Short-Range Communication (DSRC) standard has been formulated to meet these needs. While at the application layer, DSRC adopts the successful Internet-based Public Key Infrastructure (PKI) framework to safeguard the vehicles, PKI alone cannot meet all of the security and privacy requirements. In year 1 of this research the research team will focus on security. The width of the Control Channel (CCH) and the type of the utilized authentication framework, limit the number of vehicles that could concurrently communicate; while some frameworks have lower communication overhead, others have better anonymity qualities. The team will investigate an alternating authentication scheme to match the situational neighborhood of vehicles; if a vehicle encounters a congested environment, it switches to the light-weight Identity Based Cryptography (IBC) authentication. If the vehicle witnesses a sparse vicinity, it switches to a highly anonymous Group signature (GS) authentication. The alternating authentications scheme exhibits better performance than the case of using a single authentication throughout the existence of the network. When analyzed, the proposed approach has proved to be secure, computationally fast, and preserves the vehicle's anonymity level. This work will be extended to test the scheme's performance and computational requirements for different cluster sizes, for a Poisson distribution of the vehicle arrival rate, and when the competition for the CCH channel is considered.
