摘要：VANET is a subclass of MANET in which each vehicle acts as a node. In VANET Road Side Units(RSUs) are responsible for distributing group private keys and managing vehicles in a localized manner for every 100to 300 m. Then, use a Hash Message Authentication Code (HMAC) to avoid time consuming CRL checking and toensure the integrity of messages. Cooperativemessage authentication scheme is mainly used for reducing theauthentication burden. The scheme is more efficient in terms of authentication speed and privacy. Congestion controlscheme is introduced to monitor and regulate the traffic levels, So with the help of this approach whenever there is aproblem of congestion and emergency message occurs, the congestion control can reserve time slots by dynamicallypartitioning the beacon interval without the expense of beacons for reducing the traffic.
