Secure road side infrastructures play an important role in vehicular communication of IoT environment, but few related efforts have been made. Lacking trusted certification, scalability, efficiency in vehicle-only network causes various attacks. In this paper, the authors build a secure and scalable infrastructure system, in which distributed CA, log infrastructures and road side infrastructures are deployed autonomously, certification and logging improve the system security. To build autonomous networks, gateways are preselected, other nodes gather afterwards, new gateway are generated automatically when network scale increases.
