In order to enhance the security of vehicular ad hoc networks (VANETs). By dividing the roadside units (RSUs) into application-RSUs (AP-RSUs) and authentication-RSUs (AU-RSUs) in application layer, we give a new security scheme for VANETs. This functional division of RSUs makes VANETs more logically clear. AU-RSUs record vehicles' real identities and assign temporary certificates to them. The temporary certificates can help vehicles hide their real identities. Hence, the scheme not only can guarantee the vehicle anonymity, but also can realize the vehicle traceability.
