Abstract :
Road side infrastructures with certification and service aid are important in secure vehicular communication. Few road side infrastructure issues have been addressed in former studies. Lacking trusted certification, scalability, efficiency and intrusion detection in vehicle-only network causes various attacks. In this paper we propose an autonomous road side infrastructure network approach. Some road side infrastructures are preselected administratively and the others gather towards the formers autonomously. Road side infrastructures in the same autonomous network cache and forward certificates, which are invisible to other autonomous network. In our approach, CA cluster in different regions comply with corresponding scalability strategy and regional policy. A distributed IDS system integrated with the CA database provide further security protection from malicious vehicles with legal certificates. The certificate caching and forwarding schema accelerates authentication. In our analysis, our approach has a better efficiency, scalability and security guarantee than former road side infrastructure designs.
