METHOD FOR A PUBLIC-KEY INFRASTRUCTURE FOR VEHICULAR NETWORKS WITH LIMITED NUMBER OF INFRASTRUCTURE SERVERS

摘要

A system, and method related thereto, for providing a vehicular communications network public-key infrastructure. The system comprises a plurality of communications infrastructure nodes and a plurality of vehicles each having a communications component. The communications component provides vehicle to vehicle (V2V) communications, and communications via infrastructure nodes. A communications security component in each of the plurality of vehicles provides security for the communications between the plurality of vehicles using a plurality of security modules. The security modules include a certificate management module. A public key interface module may include a public key, a private key, an anonymous key and a management key. The system further includes a detection and response module for attack detection and attack mitigation. The communications security component assigns and installs at least one security key, a certificate of operation, and a current certificate revocation list. The communications component provides secure communications between the plurality of vehicles.
