“…Accurate and up-to-date membership views are needed in platoons for two main reasons, (1) reliable group communication (2) for the leader to make safe and appropriate driving decisions. The key challenges to implementing accurate membership for vehicular environments are the unreliable nature of wireless communication, the high level of dynamism in vehicle movements, interaction with non-automated vehicles [22], and the increased security risks associated with external communication interfaces.…”

Abstract-Cooperative vehicular systems have the potential to significantly increase traffic efficiency and safety. However, they also raise the question of to what extent information that is received from other vehicles can be trusted. In this paper we present a novel approach for increasing the trustworthiness of cooperative driving through a model-based approach for verifying membership views in vehicular platoons. We define a formal model for platoon membership, cooperative awareness claims, and membership verification mechanisms. With the help of a satisfiability solver, we are able to quantitatively analyse the impact of different system parameters on the verifiability of received information. Our results demonstrate the importance of cross validating received messages, as well as the surprising difficulty in establishing correct membership views despite powerful verification mechanisms.

Abstract-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.Index Terms-Vehicular ad-hoc networks (VANETs), security model, trust.

“…As the deployment of VANETs will be gradual, in early-stage VANETs, only a small fraction of the vehicles on the road will be smart vehicles with the capability to participate in the network [3] [20]. In such a system, neighboring-based Sybil attack defense [9][16] [27] may not be applicable.…”

Abstract-In this paper, we propose two certificate mechanisms for preventing the Sybil attack in a vehicular ad hoc network (VANET): the timestamp series approach and the temporary certificate approach. We focus on an early-stage VANET when the number of smart vehicles is only a small fraction of the vehicles on the road and the only infrastructure components available are the roadside units (RSUs). Unlike previously proposed schemes, which require a dedicated vehicular public key infrastructure to certify individual vehicles, in our approach the RSUs are the only components issuing certificates. The vehicles can obtain certificates by simply driving by RSUs, without the need to pre-register at a certificate authority (CA).The timestamp series approach exploits the fact that due to the variance of the movement patterns of the vehicles, it is extremely rare that the two vehicles pass by a series of RSUs at exactly the same time points. The vehicles obtain a series of certificates signed by the RSUs, which certify their passing by at the RSU at a certain timepoint. By exploiting the spatial and temporal correlation between vehicles and RSUs, the Sybil attack can be detected by checking the similarity of timestamp series.In the temporary certificate-based approach, an RSU issues temporary certificates valid only in a particular area for a limited time. To guarantee that each vehicle is assigned only a single certificate, at the issuance of the first certificate it is required that the RSU physically authenticate the vehicle. When driving by the subsequent RSUs, however, the certificate can be updated in chained manner. By guaranteeing that each vehicle is issued a single certificate in a single area, the Sybil attack is prevented.We provide mathematical analysis and simulation for the timestamp series approach. The simulation shows that it works with a small false-positive rate in simple roadway architecture.
