Vehicular Ad-Hoc NETwork (VANET) is an emerging area of wireless networks which allows vehicles to communicate enabling Intelligent Transportation System (ITS). Immense amount of research is going on both by industry and academia. In vehicular communication there occurs frequent handover because of the high speed of vehicles and hence there is always a requirement of secure and fast authentication for a seamless handover to take place. In this paper, the authors propose an authentication scheme that will not only provide security and privacy but also will reduce the storage and communication overhead increasing the efficiency.
