CRL DISTRIBUTION USING AN ALTERNATIVE COMMUNICATION MEDIA FOR VEHICULAR NETWORKS
Efforts on vehicular network security have been undertaken, with consensus on utilizing public key cryptography to secure communications. However, how to efficiently revoke nodes certificates represents a major challenge in vehicular networks. Certificate revocation lists (CRLs) should be distributed quickly to every vehicle within the networks to protect them from malicious users and malfunctioning equipment as well as to increase the overall security and safety of the vehicular networks. In this paper, we propose a Terrestrial-Digital Multimedia Broadcasting (T-DMB) aided distribution method for CRL distribution. The method can broaden breadth of network coverage and can get real-time delivery and enhanced transmission reliability using an alternative communication media thus, T-DMB data broadcasting channels. Even if road side units are sparsely deployed or, even not deployed, vehicles can obtain recent CRLs from T-DMB infrastructure. In addition, to broadcast CRLs over T-DMB infrastructure, we design a new Transport Protocol Expert Group (TPEG) CRL application followed by TPEG standards.
