Recently, the focus of smart vehicles that relied on sensors has changed due to advances in the Internet of Things (IoT) and networks.Various information can be exchanged while applying IoT technology to automobiles, which allows drivers to pursue convenience.The Internet of Vehicles (IoV) is a technology that combines Intelligent Transportation Systems (ITS) and IoT, and vehicular ad-hoc network (VANET), the current communication, is being developed into IoV [1].IoV allows autonomous vehicles to communicate with other autonomous vehicles or various road infrastructures to understand road conditions.Autonomous vehicles recognize the road environment with sensing techniques such as cameras, radars, and riders, and identify road topography using High-definition (HD) maps [2] and the Global Navigation Satellite System (GNSS) [3].*Author for correspondence Furthermore, autonomous vehicles communicate with objects on the road using the Vehicle to Everything (V2X) communication, collect information, and plan routes based on it [4].Autonomous vehicles collect various situational information, such as road control areas caused by accidents and roads where rush hour occurs through V2X communication.Using this information, automatic vehicles can avoid road congestion and navigate and drive on roads that allow for the shortest travel time [4].V2X communication that can collect information is a necessary technology for autonomous driving, and the stability of the network must be ensured while the vehicle is communicating.This is because such information can be sent and received in real time to cope with the situation.Therefore, for autonomous driving, a high network transmission speed must be guaranteed and data must be protected from attackers [5].An attacker infiltrates networks used by autonomous vehicles to delete or forge data.Accidents occur because autonomous vehicles receive forged data or fail to Research
