Abstract

To protect the members of the vehicular networks from malicious users and malfunctioning equipments, certificate revocation list (CRL) should be distributed as quickly and efficiently as possible without over-burdening the network. The common theme among existing methods in the literature to reduce distribution time is to reduce the size of the CRL, since smaller files can be distributed more quickly. Our proposal has been concerned with the problem of how to reduce the size of CRL effectively. We propose a regional CRL distribution method that introduces partitioned CRLs corresponding to certificate authority (CA) administrative regions. A regional CRL includes only neighbouring vehicle’s revoked certificates and distributed to vehicles within one CA region. Consequently, since there is no need to process full CRLs by all vehicles, the method can reduce computational overhead, long authentication delay, message signature and verification delay, and processing complexity imposed by full CRL distribution methods.
