Vehicular Ad-hoc NETworks (VANET) can provide communications between vehicles or infrastructures. It provides the convenience of driving and the secure driving to reduce accidents. In VANET, the security is more important because it is closely related to accidents. Additionally, VANET raises a privacy issue because it can track the location of vehicles and users' identity when a security mechanism is provided. In this paper, the authors analyze the problem of an existing solution for security requirements required in VANET, and resolve the problem of the existing method when a key management mechanism is provided for the security operation in VANET. Therefore, they show suitability of the Long Term Evolution (LTE) in VANET for the solution of this problem.
