Certificate Revocation Management in VANET

Abstract — Vehicular Ad hoc Network security is one of the hottest topics of research in the field of network security. One of the ultimate goals in the design of such networking is to resist various malicious abuses and security attacks. In this research new security mechanism is proposed to reduce the channel load resulted from frequent warning broadcasting happened in the adversary discovery process – Accusation Report (AR)- which produces a heavy channel load from all the vehicles in the road to report about any new adversary disovery. Furthermore, this mechanism will replace the Certificate Revocation List (CRL), which cause long delay and high load on the channel with Local Revocation List (LRL) which will make it fast and easy in the adversary discovery process
