Abstract:

A vehicular ad hoc network (VANET) allows vehicles to share traffic information and to alert each other of emergency events. To achieve this goal, a security mechanism must be designed to guarantee that no malicious vehicles can intercept, manipulate, or modify the traffic information without being detected. In this paper, we present two novel approaches to provide reliable traffic information propagation in a VANET: two-directional data verification, and time-based data verification. The two-directional data verification approach uses vehicles in both driving directions of a two-way road as two separated media channels. A traffic message will be transmitted through both channels. A recipient vehicle verifies the message integrity by checking if data received from both channels are matched. This approach exploits the fact that it is difficult and costly to have two collaborative vehicles on both driving directions in the same region. The time-based data verification approach uses vehicles in the opposite driving direction to propagate a traffic message by issuing the message to those vehicles twice with certain time delay. It relies on the time delay between these two messages and the mobility of vehicles to cause two separated groups of vehicles on the opposite direction carrying and propagating the message. 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.

      A vehicular ad hoc network (VANET) allows vehicles to share traffic
      information and to alert each other of emergency events. To achieve this
      goal, a security mechanism must be designed to guarantee that no malicious
      vehicles can intercept, manipulate, or modify the traffic information
      without being detected. In this paper, we present two novel approaches to
      provide reliable traffic information propagation in a VANET:
      two-directional data verification, and time-based data
      verification.
      The two-directional data verification approach uses vehicles in both
      driving directions of a two-way road as two separated media channels. A
      traffic message will be transmitted through both channels. A recipient
      vehicle verifies the message integrity by checking if data received from
      both channels are matched. This approach exploits the fact that it is
      difficult and costly to have two collaborative vehicles on both driving
      directions in the same region. The time-based data verification approach
      uses vehicles in the opposite driving direction to propagate a traffic
      message by issuing the message to those vehicles twice with certain time
      delay. It relies on the time delay between these two messages and the
      mobility of vehicles to cause two separated groups of vehicles on the
      opposite direction carrying and propagating the message. Compared with the
      popular public-key based security systems, the proposed approaches are
