摘要：A system and method for assigning certificates and reducing the size of thecertificate revocation lists in a PKI based architecture for a vehicle wireless
communications system that includes separating a country, or other area, into geographicregions and assigning region-specific certificates to the vehicles. Therefore, a vehicle needonly process certificates and certificate revocation lists for the particular region that it istraveling in. Vehicles can be assigned multiple certificates corresponding to more thanone region in the vehicles vicinity as advance preparation for possible travel or
transmission into nearby regions. Further, the expiration time of certificates assigned tovehicles corresponding to a given geographic region can be tailored to be inverselyproportional to the distance from a registered home region of the vehicle. A scalabledesign for a back-end certifying authority with region-based certificates can also beprovided.
