Geolocation-Based Trust for Vanet´s Privacy

Research in vehicular ad hoc networks (VANETs) has evolved considerably over the last years. Security and privacy in VANETs have recently appealed special interest in the research community. In this paper we overview the main privacy concepts and explain why this concept is fundamental for wide adoption of VANETs. A set of privacy requirements for VANETs are established and studied, towards proposing a novel mechanism beyond the use of pseudonyms. In particular, this research demonstrates that there are still several challenges concerning privacy which solution is feasible to be extrapolated from highly demanding environments like e-Health. This paper reports our work in progress mainly describing the basis of a privacy mechanism that uses an authorization paradigm based on a Mandatory Access Control model and a novel mechanism that propagates trust information based on a vehicle´s geolocation.
