TL;DR: This work proposes a VANET key management scheme based on Temporary Anonymous Certified Keys (TACKs), which efficiently prevents eavesdroppers from linking a vehicle's different keys and provides timely revocation of misbehaving participants while maintaining the same or less overhead for vehicle-to-vehicle communication as the current IEEE 1609.2 standard.

Abstract: Vehicular Ad Hoc Networks (VANETs) require a mechanism to help authenticate messages, identify valid vehicles, and remove malevolent vehicles. A Public Key Infrastructure (PKI) can provide this functionality using certificates and fixed public keys. However, fixed keys allow an eavesdropper to associate a key with a vehicle and a location, violating drivers' privacy. In this work we propose a VANET key management scheme based on Temporary Anonymous Certified Keys (TACKs). Our scheme efficiently prevents eavesdroppers from linking a vehicle's different keys and provides timely revocation of misbehaving participants while maintaining the same or less overhead for vehicle-to-vehicle communication as the current IEEE 1609.2 standard for VANET security.

TL;DR: A new type of signature for a group of persons, called a group signature, which has the following properties: only members of the group can sign messages; and if necessary, the signature can be "opened", so that the person who signed the message is revealed.
