Security Hardened and Privacy Preserved Vehicle-to-Everything (V2X) Communication

Abstract

Vehicle-to-everything (V2X) communications have recently gained concentration of researchers for both, academia as well as industry. In the V2X system, the information is communicated from vehicle sensors to other vehicles, infrastructure, pedestrians, and mobile network cloud through high-bandwidth reliable links [1–4]. &e technology may greatly improve the driver’s awareness of imminent hazards, thereby reducing the severity of accidents, fatalities, or possible collisions with other vehicles. &e V2X technology brings efficiency through creating warning alerts for drivers, imparting the information of alternative routes for avoiding possible traffic congestions and pinpointing available parking spaces. Such critical situations might become problematic if the security and privacy of V2X communication system is compromised [5–8]. &us, V2X vehicles along with efficiency, reliability, and safety parameters require more secure and robust communication protocols to meet the upcoming security challenges. Moreover, the wireless nature of the system might become challenging in affording secure and ubiquitous connectivity to the V2X network [9–13]. &is is crucial to create a fail-safe infrastructure of modern traffic scenario regarding smart cities since security and privacy issues are quite prevalent in our daily lives.
