Service-oriented vehicular ad hoc networks (VANETs) are expected to support the diverse infrastructure-based commercial services, including Internet access, real-time traffic concerns, video streaming, and content distribution. The success of service-oriented VANETs depends on the underlying communication system to enable the user devices to connect to a large number of communicating peers and even...
Vehicular communications are envisioned to play a substantial role in providing safety in transportation by means of safety message exchange. However, the deployment of vehicular networks is strongly dependent on security and privacy features. In this paper, we present a Protocol for Anonymous Authentication in Vehicular Networks (PAAVE) to address the issue of privacy preservation with authority...
Location privacy is a main concern in vehicular communications where vehicles have to broadcast traffic routine information frequently. A promising approach to prevent a vehicle from been tracked suggests vehicle to change pseudonyms in regions called mix-zones, where the adversary cannot eavesdrop the vehicular communication. However, the deployment problem of mix-zones has not been well addressed...
In this paper, we propose a secure data downloading protocol with privacy preservation in vehicular ad hoc networks (VANETs). In the data downloading application, vehicles send requests, such as where is the nearest gas station, at a road side unit (RSU) and receive the corresponding responses from application servers via current or the following RSUs. It would be easy for eavesdroppers to get vehicles'...
Roadside Units (RSUs) aided distributed certificate service is a promising approach for ensuring security and privacy preservation in vehicular ad hoc networks (VANETs), where the existence of RSUs is critical for such a scheme in order to allow On-Board Units (OBUs) to update their short-time certificates on time. However, RSUs may only be deployed at some critical points along roads due to the cost...
Roadside units (RSUs) aided certificate service is a promising approach for ensuring security and privacy preservation in vehicular ad hoc networks (VANETs). In existing approaches, a vehicle can update certificate only when it passes by RSUs, however, this is impractical in many scenarios. Consequently, if there are no RSUs on the original driving trip, drivers have to adjust routes which means wasting...
