Abstract
AbstractWe propose a new privacy-enhancing beacon scheme in Vehicle-to-Everything (V2X) communication systems and evaluate its effectiveness based on a simulation. With this scheme, vehicles dynamically adjusts their periodic transmission of Cooperative Awareness Message (CAM) and Basic Safety Message (BSM) messages based on the observation of surroundings and transmit these messages only when it is necessary. This new scheme addresses the gap in standards where continuous transmission of broadcast-based unencrypted vehicle information is assumed but may not be needed under certain circumstances. Our beacon message does not convey any privacy-linking information. This way, this new scheme enhances privacy protection of vehicle owners by limiting the transmission of information that can be linked to a particular vehicle. The complexity of its processing in both transmitting and receiving ends is kept at minimum and is simpler than CAM and BSM processing. Our simulation result indicates that this new scheme is highly effective if the density of vehicles with V2X technology is limited.KeywordsV2XVehicle communicationPrivacy protectionPseudonymPseudonym usageBeacon message
