“…VANET has gone through ample amount of research to provide drivers and consumers with safe, reliable, and infotainment-rich driving experience. Nevertheless, automobile companies are still reluctant to deploy VANET in full scale due to security and privacy challenges [1]. Since VANET is directly related to human lives, security and privacy issues are of paramount importance and have been addressed for a considerably long time by the academia and industry [2][3][4].…”

Abstract-Over the last couple of years, traditional VANET (Vehicular Ad Hoc NETwork) evolved into VANET-based clouds. From the VANET standpoint, applications became richer by virtue of the boom in automotive telematics and infotainment technologies. Nevertheless, the research community and industries are concerned about the under-utilization of rich computation, communication, and storage resources in middle and high-end vehicles. This phenomenon became the driving force for the birth of VANET-based clouds. In this paper, we envision a novel application layer of VANET-based clouds based on the cooperation of the moving cars on the road, called CaaS (Cooperation as a Service). CaaS is divided into TIaaS (Traffic Information as a Service), WaaS (Warning as a Service), and IfaaS (Infotainment as a Service). Note, however, that this work focuses only on TIaaS and WaaS. TIaaS provides vehicular nodes, more precisely subscribers, with the fine-grained traffic information constructed by CDM (Cloud Decision Module) as a result of the cooperation of the vehicles on the roads in the form of mobility vectors. On the other hand, WaaS provides subscribers with potential warning messages in case of hazard situations on the road. Communication between the cloud infrastructure and the vehicles is done through GTs (Gateway Terminals), whereas GTs are physically realized through RSUs (Road-Side Units) and vehicles with 4G Internet access. These GTs forward the coarse-grained cooperation from vehicles to cloud and fine-grained traffic information and warnings from cloud to vehicles (subscribers) in a secure, privacy-aware fashion. In our proposed scheme, privacy is conditionally preserved wherein the location and the identity of the cooperators are preserved by leveraging the modified location-based encryption and, in case of any dispute, the node is subject to revocation. To the best of our knowledge, our proposed scheme is the first effort to offshore the extended traffic view construction function and warning messages dissemination function to the cloud.

“…First, a secure boot-up process exists through which the appropriate Authority (e.g. a Certification Authority, CA) installs all cryptography-related materials into vehicles, particularly in a secure cryptographic device called Hardware Security Module (HSM) [8]. This material contains the public-private keypairs along with the corresponding pseudonym-based public key certificates (referred to as Cert E(t) ).…”

There are traffic situations (e.g. incorrect speeding tickets) in which a given vehicle's driving behavior at some point in time has to be proved to a third party. Vehicle-mounted sensorial devices are not suitable for this matter since they can be maliciously manipulated. However, surrounding vehicles may give their vision on another one's behavior. Furthermore, these data may be shared with the affected vehicle through VANETs. In this paper, a VANET-enabled data exchange mechanism called WEVAN is presented. The goal of this mechanism is to build and verify evidences based on surrounding vehicles (called witnesses) testimonies. Due to the short-range nature of VANETs, the connectivity to witnesses may be reduced with time -the later their testimonies are requested, the lower the amount of witnesses may be. Simulation results show that if testimonies are ordered 5 seconds later, an average of 38 testimonies may be collected in highway scenarios. Other intervals and road settings are studied as well.
