Abstract--Due to increase in traffic it is very necessary to enhance the efficiency and safety of road traffic. Vehicular ad-hoc networks which are created by applying the principles of mobile ad hoc networks (MANETs),whichallow vehicles to broadcast ad hoc messages to other vehicles and remind drivers to slow down their speed to avoid accidents or to change their routes. For securing vehicular networks, an authentication scheme is very important to ensure that messages are sent by authorized  vehicles and not corrupted during transmissions.. An attacker can easily disrupt the function of VANETs by  sending fake messages  to gain unfair advantage on the road or to cause serious accidents. Hence the sender vehicles should be authenticated by the receiver before taking any action based on the received safety message. Also there is a need to encrypt these messages. When it is about the security of the very important persons like the Prime minister, scientists, army Personals and many more  travelling on road. Their safety is of utmost importance. Most of the previously proposed schemes cannot support privacy preservation between roadside units (RSUs) and vehicles.  In this paper generation of token by a base station which is a Trusted Authority, is proposed for short communication .This trusted authority provides unique ids to special groups and registers the vehicles. for short communications it provides a temporary token to a nearest user and discards the generated token after the communication.
