Security certificate revocation list distribution for vanet

ABSTRACT

In a VANET, a certificate authority issues keys and

certificates to vehicles. Each vehicle distributes these certificates to other VANET participants and subsequently signs messages against these certificates. If the certificate authority needs to revoke a certificate (e.g. due to a breach of trust), it universally distributes a certificate revocation list. We propose a method for car-to-car epidemic distribution of certificate revocation lists which is quick and efficient. Large-scale simulations based on realistic mobility traces show that this epidemic model significantly outperforms methods that only employ road side unit distribution points.
