vehicular networks security privacy safety vehicular ad hoc networks (VANET) wireless Security and Privacy of Vehicular ad hoc Networks Supporting Revocation Hu, Yih-Chun Hu, Yih-Chun Borisov, Nikita Kumar, P.R.

Haas, Jason J. 2010-08-20T17:57:15Z 2010-08-20T17:57:15Z 2010-08-20T17:57:15Z 2010-08 In vehicular ad hoc networks (VANETs), vehicles communicate with other vehicles or fixed infrastructure, called road-side units (RSUs). One of the main goals for VANETs is to improve vehicle safety. Work has begun on defining and implementing VANET safety applications. VANET security services will be standardized in IEEE 1609.2. Safety application message broadcasts will include reports of vehicles’ positions, velocities, and accelerations. Vehicles will use these messages as the basis for presenting warnings to drivers. An insecure, distributed, wireless, easily accessible vehicular safety system could easily be taken advantage of and actually result in poorer vehicular safety. VANET safety messages need to be secured to mitigate falsified reports from malicious actors and to detect erroneous reports generated by malfunctioning vehicles. Concretely, safety messages must be authenticated to a vehicle, and a malicious or malfunctioning vehicle (i.e., one that creates falsified or erroneous messages) should have its credentials (i.e., its certificate or certificates) revoked. In the eyes of government agencies and of automobile manufacturers, a deployable VANET must not only be built on secure safety applications but must also protect a user’s privacy. Specifically, consumers may be averse to the privacy implications of using a vehicle that broadcasts highly accurate reports of its location. This work addresses VANET security and privacy in the following ways. It investigates how specific authentication mechanisms affect network performance. Next, it provides a scheme for the swift access to time-sensitive security information. This work evaluates what user privacy is obtainable based on sharing authentication keys. Further, this work evaluates VANET network-layer and application-layer performance in the broader context of safety application communication requirements. Additionally, it studies providing enhanced privacy to VANET users through identity obfuscating radios.
