RT Journal Article T1 Security models in Vehicular ad-hoc networks: a survey A1 Fuentes, José María de A1 González-Manzano, Lorena A1 González-Tablas, Ana Isabel A1 Blasco Alís, Jorge AB The security and privacy issues of vehicular ad-hoc networks (VANETs) must be addressed before they are implemented. For this purpose, several academic and industrial proposals have been developed. Given that several of them are intended to co-exist, it is necessary that they consider compatible security models. This paper presents a survey on the underlying security models of 41 recent proposals. Four key aspects in VANET security are studied, namely trust on vehicles, trust on infrastructure entities, existence of trusted third parties and attacker features. Based on the survey analysis, a basic mechanism to compare VANET security models is also proposed, thus highlighting their similarities and differences.
