DISTRIBUTION METHOD FOR CERTIFICATE INVALIDATION LIST, TRANSMISSION NODE USED THEREFOR, AND RELAY NODE

摘要

PROBLEM TO BE SOLVED: To provide a distribution method for certificate invalidation list that effectively distributes a certificate invalidation list through vehicle-to-vehicle communication even under a highly dense environment of vehicles, and to provide a transmission node used therefor and relay node.

SOLUTION: The transmission node codes a certificate invalidation list received from the authentication station using random network coding, and distributes coded data by broadcasting through vehicle-to-vehicle communication. The relay node recodes the received coded data for each fixed interval for broadcasting through vehicle-to-vehicle communication.
