V2X (Vehicle to Everything) system ensures safety by sending BSM (Basic Safety Message) including vehicle information and using the MBD (Mis-Behavior Detection) system which is able to classify abnormal or malicious vehicles. However, as vehicle information is exposed for safety, problems related to privacy and security inevitably arise. In particular, location and travel route privacy has been issued recently and many studies have been conducted to protect vehicle location privacy. The problem of conventional studies is that the privacy solutions did not consider V2X system including MBD. Therefore, this paper summarizes the conventional location privacy solutions and analyzes how MBD affects these solutions In addition, based on this analysis, we propose a location privacy solution with GPS position accuracy which is most suitable for the current V2X security system considering BSM and MBD.
