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 arc much simpler and cheaper to implement. especially during the initial transition stage when a mature VAN FT network infrastructure does not exist.
