“…CRL distribution is of central importance and it is the final and definitive line of defense [1], [4], [8], [8], [25], [30]: only the VPKI can ''ultimately'' revoke a vehicle by including its unexpired certificates' serial numbers in a CRL. The literature proposes distribution of the CRL via RSUs [19] and car-to-car epidemic communication [15], [16], [18], with enhancements on the distribution of pieces [20], [21] evaluated in [31]. A naïve solution would be to digitally sign the entire CRL and broadcast it; however, it imposes difficulties in downloading a large CRL file and exchanging it over short contact period (with an RSU or a peer).…”

“…A main concern, relevant to all proposals in the literature [15], [16], [18], [19], [20], [21] is efficiency and scalability, essentially low communication and computation overhead even as system dimension grows. Consider first typical operational constraints: the average daily commute time is less than an hour (on average 29.2 miles and 46 minutes per day) [10], [22], [23] while the latencies for the dissemination of a full Certificate Revocation List (CRL) can exceed the actual trip duration [24].…”

“…Nowatkowski [20] proposed two protocols to optimize the CRL distribution overhead. The first is Most Pieces Broadcast (MPB).…”

“…This paper examines only MPB. Reducing the number of OBUs contending for the channel will increase the number of CRL pieces successfully received by the OBUs in the VANET [5]. This research combines aspects of the approaches from EPFL, Laberteaux, Haas and Hu, and UCLA to develop a better solution for distributing CRLs and other large files in a VANET environment.…”

“…This paper discusses the details, modeling, and simulation results of a new method for CRL distribution in a VANET environment. This method was first introduced in [5], which was based only on preliminary results. This paper provides a much more detailed examination of the method, entailing an ns-3 [6] simulation of the distribution of a 1 megabyte CRL file using realistic vehicle mobility trace files [7].…”
