Abstract: In vehicular ad hoc network, vehicles can share traffic/emergency information. The information should not be modified/manipulated during transmission without detection. We present two novel approaches to provide reliable traffic information propagation: two-directional data verification, and time-based data verification. The traffic message is sent through two (spatially or temporally spaced) channels. A recipient vehicle verifies the message integrity by checking if data received from both channels are matched. Compared with the popular public-key based security systems, the proposed approaches are much simpler and cheaper to implement, especially during the initial transition stage when a mature VANET network infrastructure does not exist.

Keywords: VANET; vehicular ad hoc networks; initial deployment; secure data propagation; data security; information sharing; data verification; message integrity; information security; vehicle communications.
