What is Inter-Vehicle Communications?
Recent developments in mobile computing devices enable us to increase the vehicles’ safety on highways. This can be realized through inter-vehicle communication (IVC) by exchanging safety related information among the nearby vehicles. These include braking data from the cars ahead, road-conditions sensed by the surrounding cars and the data from other sensors in a vehicle.
What is Highway Safety Messaging?
In order to achieve improved road safety and significantly reduce the number of road fatalities, local sensors alone are not sufficient. If we transmit sensor information and information about the maneuvers among the neighborhood vehicles, we can achieve the goal of improved road safety. If a front vehicle suddenly applies emergency brakes, our idea helps the rear car driver to apply early brakes which in turn will prevent rear end collision.
Why do we need secure IVC?
Wireless communications, especially in the case of vehicular network, is normally prone to more security threats than their wired counterparts. Several kinds of attacks can be launched to interfere and destroy the communication due to the unique characteristics of IVC, such as size of the network, speed of vehicles, and dynamic network topology, etc. Thus, security becomes one of challenging issue. For example, it is necessary to make sure that life-critical information cannot be inserted or modified by any attackers. At the same time privacy of the drivers and passengers must be protected.
