  • 摘要:Amongst many different communication paradigms, Vehicular ad hoc networks (VANET’s) are an areaof developing techniques. It has become an upcoming technology of this modern world in vehicular communications.The main reason of using VANET is to exchange live messages regarding traffic congestions. A Trusted authority (TA)is designed to provide authentication services for users and managing keys of several users. Like in any other networksin VANET also there is a necessity to maintain authentication and confidentiality among the users. To authenticate theusers the authority classifies users into primary, secondary and unauthorized users. First, a co-operative messageauthentication scheme is proposed by which the authentication burden of the TA is shared among the alreadyauthenticated primary users of the VANET. Second, a group key management technique is proposed by which anumber of users are grouped together and one key-pair is assigned to the whole group. This is also used to update/rekeythe key periodically instead of after every join/leave operations. Using these schemes the VANET users should be ableto send and receive messages to and from authority and users through the road side units (RSU’s) with a full of securedprocess.
