A Comprehensive Review of Authentication Schemes in Vehicular Ad-Hoc Network

Vehicular ad-hoc network (VANET) has been gaining importance due to the fast growing technology as well its requirements in intelligent transportation systems (ITS) and vehicular social (VSN). VANET facilitates vehicle (V2V) infrastructure (V2I) communication improves ride quality with value added services. The number of connected vehicles is expected grow a huge enormous exchange safety non-safety messages which are susceptible security privacy threat. To ensure secured communication, must implement an authentication protocol resist attack preserve privacy. In this paper, detailed discussion on taxonomy for schemes presented. have compared security, scalability requirement. use recent technologies such 5G, 5G-SDN, Blockchain design low cost, computational overhead discussed. Finally, paper concludes open challenges authentication. This new avenues researchers working domain VANETs.
