In its latest report, the United States National Highway Traffic Safety Administration (NHTSA) registered some 37,300 fatalities for the yearly victims of motor vehicle accidents in 2017. Vehicle-to-everything (V2X) is playing an important role in improving road safety, traffic efficiency and infotainment systems. With the growth of the connected vehicle technology, V2X is emerging as a key component in the rapid rise of this technology. Therefore, researchers think that development of robust wireless communication through efficient V2X technologies can significantly improve the vehicular environment. The highly dynamic environment and the mobility factor appear to be challenging for implementation of V2X technology. Similar to other wireless technology, the security issues are also key concerns in V2X.

In this survey, we highlight and discuss the main security issues of V2X. Particularly, the main objective of this …
