A Design and Realization of Traffic Information Security Scheme based on GPS

摘要

The traffic information based on GPS/COMPASS is widely used in the intelligent transportation system. The security of traffic information transmission has many challenges that are presented in the paper. It designs a security scheme for message transmission between the vehicle and the data a collection server and between the data collection server and the traffic management center. It indicates the realization of the security scheme. The security scheme ensures the integrity of the data and implements mutual authentication among the vehicle, the data collection server, and the traffic management center using X.509 certification.
