Description: TOPIC: SEGMENTED VIRAL DISTRIBUTION OF CERTIFICATE REVOCATION LISTS (CRL) FOR THE SECURITY CREDENTIAL MANAGEMENT SYSTEM (SCMS)
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A
ABSTRACT:
Connected Vehicles technology facilitates communication among vehicles to increase road safety by broadcasting Basic Safety Messages (BSMs). While communication increases traffic awareness to avoid collisions, it also creates a new attack surface, requiring a mechanism to secure Vehicle-to-Vehicle (V2V) communication. Vehicular Public Key Infrastructure (V-PKI) manages security credentials for vehicles, ensuring BSM integrity and maintaining V2V availability while protecting car users privacy. The leading V-PKI implementation is the Security Credential Management System (SCMS), which allows vehicles to authenticate each other using certificates. Efficient distribution of the Certificate Revocation List (CRL) plays a critical rule in SCMS to evict misbehaved vehicles from the communication system. However, the CRL distribution method has not been defined yet.
This research focuses on efficient CRL distribution. Novel cooperative mechanisms reduce overhead in V2V communication and increase speed of CRL dissemination while maintaining integrity of the entire list. Specifically, Segmented Viral Distribution breaks down the CRL into versioned segments that can be independently verified with SCMS without the need to verify the sender. Simulations, using VEINS, SUMO, and OMNeT++ with models coded in C, validate that this segmented viral method distributes CRL quickly and preserves availability of V2V communication while maintaining CRL integrity. This research increases the trust-level of SCMS. Future work includes experiments in V2V test sites before introducing to the standard.
