As the communications among the vehicles, the Road-Side Units ( RSU ) and the Edge Servers ( ES ) take place via wireless communication and the Internet, an adversary may take the opportunity to tamper with the data communicated among various entities in an Internet of Vehicles (IoV) environment. Therefore, it demands secure communication among the involved entities in an IoV-based Intelligent Transportation System (ITS) deployment. In this work, we design a new blockchain-enabled certificate-based authentication scheme for vehicle accident detection and notification in ITS, called BCAS-VADN. In BCAS-VADN, through the authentication process, each vehicle can securely notify accident related transactions to its nearby Cluster Head ( CH ), if an accident is detected on roads either by its own or neighbor vehicle(s). The CH then securely sends the transactions received from the vehicles to its RSU and …
