Abstract :
Vehicular ad hoc networks (VANETs) will enable new applications that increase safety and convenience of the passengers in the car. Most applications for VANETs use information provided by other cars, and road side units. Different complementary means exist to establish a trustworthy and privacy preserving system; they include certification, reputation systems, plausibility checking, and frequently changing pseudonyms. Often, these measures are tailored to specific aspects of the system and cannot easily be used by application developers, nor can they easily be combined. We present an architecture to integrate trust and privacy services for the use in vehicular environments. The main contributions of this paper are (1) an architecture for securing vehicular communications that can easily be used by application developers, (2) the principle of trust tagging including a model for trust establishment for the vehicular domain and (3) the context mix model for preserving location privacy of vehicles
