A Privacy Preserving Communication Scheme for VANETs

Abstract:

In this paper, we propose a privacy preserving communication scheme for VANETs, combining ring signature and an identity based encryption. In our scheme, all the messages which needn't keep secret but provide authenticity is signed by employing a ring signature scheme, and it provide good anonymity. And we propose a approach that collecting and disseminating pks by the help of RSU. The vehicle encrypt its pk with the RSU's identity by using a IBE scheme and send it to the nearest RSU, the RSU collect pks and form a ring, and then broadcast it to the vehicles. All vehicles in this ring can sign messages with this the same ring.
