removal of misbehaving insiders in anonymous vanets
Vehicular Ad hoc NETworks (VANETs), which provide vehicles with an easy access to exchange the up-to-date traffic status and various kinds of data, have become a promising application of mobile ad-hoc networks. In the life-critical VANETs, security issues are considered as a focal topic. One challenging problem among these issues is the insider misbehavior since it bypasses the traditional security mechanisms such as authentication. The existing works focusing on this problem do not take the privacy issue into account. Their presented solutions are paralyzed in the anonymous VANETs, where the drivers' real identity is protected. In this paper, we propose SLEP and PRP, two novel protocols to efficiently remove the misbehaving insiders from the anonymous VANETs. Through analysis and extensive simulations, we demonstrate that these two protocols can achieve high reaction speed and accuracy for both the local eviction and the permanent revocation to the misbehaving vehicles, at an acceptable cost.
