“…Such policy threatens anonymity and may prevent drivers from joining the service. On the other hand, the recent work of [21] provides unconditional anonymity in the sense that it is impossible to trace the identity of any OBU. The protocol requires four interactive rounds between the OBU and the RSU in order to establish a session key which will be used for all data transmission during the session.…”

Unlike sensor and other ad-hoc wireless networks, vehicular ad-hoc networks (VANETs) are characterized by its high mobility which allows a very short communication interval among onboard units (OBUs) and between an OBU and road-side units (RSUs). This major characterization motivates the design of communication protocols that are noninteractive or at least require a very limited number of rounds between units. The challenging issue is that such protocols must satisfy a number of security services that could be complex by their nature. In secure VANETs protocols, anonymity and traceability are two important services, yet, achieving a satisfactory security level for both of them-with acceptable complexity-is not an easy task due to the contradicting requirements: anonymous transmission must not be traceable by any individual while if a transmission is traceable, then anonymity is threatened. Existing secure VANETs protocols for anonymous and traceable transmissions either, provide unconditional anonymity where traceability and revocation are impossible, or grant trust to a thirdparty not to reveal the identity of a unit unless there is a legal reason. In this paper, we propose the first secure VANET protocol that allows authenticated transmission among OBUs and RSUs and at the same time enjoys the following properties. (i) The transmission among OBUs and RSUs is noninteractive (i.e., a one-move transmission without any interactive setup requirements). (ii) The authenticated transmission between any pair of units is anonymous (i.e., no single authority knows any information about the identity of the communicating OBU). (iii) In serious road crimes (e.g., hit-and-run, road rage, etc.) and under court order, an OBU could be traced to its clear identity. We also show how our protocol could be used to setup a confidential session between any pair of units without relying on extensive number of interactive rounds.

“…From anonymity authentication in dynamic group [1] to VANET, protocol extension [2] is based on k-anonymity model, and OBU customizes its anonymity group size which is userspecific, also called adaptive. In further protocol extension [3], OBU can do probabilistic verification to save computation cost. However, previous protocols reflects privacy in VANET limited by the pitfall of k-anonymity model.…”

“…4) We define a process how to form a group efficiently from large scale of group members, customize a small anonymity set across Application Server-RSU-OBU 3-tier conceptually. All those work are based on cooperation among RSU and OBU, and we use fully trust model between RSU and OBU instead of zero trust model seen in previous work [3]. 5) Anonymity related attack and anonymity measurement in VANET are still fuzzy terms, but we advise to adapt anonymity models in data mining to help analysis in wireless ad hoc network.…”

Abstract-Data privacy in Vehicular Ad hoc NETworks(VANET) is a practical issue currently under the research and development. Privacy preserving anonymity authentication in network is a challenging topic combining anonymity, authentication, data privacy and network. Existing anonymity authentication in VANET are based on k-anonymity model, but K-anonymity model group selection may leak information due to absence of diversity in the sensitive attribute etc., and thus group selection is a problem left unresolved. In this paper, we would like to address anonymity authentication attack issues, how to improve efficiency and sustain anonymity service using cooperation instead of zero trust model, and flexibility of vehicular side group selection to adapt changing privacy-preserving concern. Therefore, we put together design of an anonymity authentication protocol with cooperation, data privacy, and privacy-preserving data publishing considerations. Through our extensive work, we demonstrated that privacypreserving anonymity authentication in VANET could be extended with more efficiency and cooperation plays a key role.

Vehicular ad hoc networks (VANETs) are planned to be deployed within the next decade to improve driver safety, prevent collisions, and provide traffic optimization. Recent years have witnessed an increasing interest in the security schemes for VANETs as this area was relatively less explored compared to other areas such as medium access and routing. In particular, efficient authentication of the messages in a VANET with other desirable security features have been heavily studied. However, there are still several issues to be addressed before such authentication mechanisms can be readily and widely used in real-life deployments. In this paper, we examine several proposed authentication solutions and categorize them based on certain criteria. We provide a comparison of the advantages and disadvantages of the proposed schemes identifying their suitability under various conditions. Finally, to foster further research in the area, we address some of the challenges that need to be tackled in the future in order to realize the deployment of VANETs.
