Vehicular ad hoc network (VANET) is an emerging type of networks to allow vehicles on roads to communicate for driving safety. An vehicle can broadcast messages (e.g. accident information) to other vehicles. These messages may have impact on other vehicles as well as the traffic control system, so all messages must be signed and authenticated. On the other hand, privacy should be enforced while the real identity of the sender should be traceable by authorized party. In this poster, we first discuss the limitations of existing solutions. In particular, we describe an impersonation attack to one of the schemes, highlight the problem of communications overhead, and effectiveness of the message verification procedure. Then, we present the main ideas of our proposed scheme which can be shown to be secure and more effective than existing schemes.

In this paper, we propose a navigation scheme that utilizes the online road information collected by a vehicular ad hoc network (VANET) to guide the drivers to desired destinations in a real-time and distributed manner. The proposed scheme has the advantage of using real-time road conditions to compute a better route and at the same time, the information source can be properly authenticated. To protect the privacy of the drivers, the query (destination) and the driver who issues the query are guaranteed to be unlinkable to any party including the trusted authority. We make use of the idea of anonymous credential to achieve this goal. In addition to authentication and privacy-preserving, our scheme fulfills all other necessary security requirements. Using the real maps of New York and California, we conducted a simulation study on our scheme showing that it is effective in terms of processing delay and providing routes of much shorter travelling time.

“…Most of the pseudonym updating schemes use the asymmetric 7,8 and symmetric cryptography, and identity-based cryptography method. 9,10 Since the pseudonym certificate is only valid during a short time, vehicle must request to CA for updating its pseudonym; the communication cost is not negligible. Although symmetric cryptography scheme [11][12][13] is more efficient, however, the key distribution is impractical in many network environment.…”

With the development of the vehicular ad hoc network, the security and privacy are now becoming vital concerns, especially when the attacker owns more and more resources. In order to address these concerns, a dynamic anonymous identity authentication scheme is proposed using Elliptic Curve Discrete Logarithm Problem and blockchain method, which guarantees the security and fast off-line authentication for vehicle-to-infrastructure. Specifically, a dynamic pseudonym key is generated using tamper proof device (TPD) for off-line authentication and anonymity when a vehicle roams among different roadside units' (RSUs) communication ranges. Even if all RSUs are compromised, vehicle's identity is still privacy. Moreover, two additional design goals are more suitable for the practical environment: (1) the reduced assumption of TPD;(2) certification authority can trace vehicle under the authorization by law. KEYWORDSblockchain, dynamic anonymous authentication, ECDLP, VANET | INTRODUCTIONWith the development of the transportation industry, unmanned technology has received more and more attention from the academic and technical field; however, sometimes its safety is questioned. In particular, on 22 March 2018, a serious accident occurred that Uber's self-driving car crashing into a pedestrian in Tempe, Arizona. Especially, the most common accidents are due to that the in-vehicle sensors are not able to perfectly identify pedestrians, vehicles, and static obstacles and the low range of vehicle sensors cannot give the vehicle enough reaction time. For example, in May 2016, the Model S hits the truck that was turning in the auto-driving state. Because the truck body was reflective, the camera did not recognize the opposite truck. With the development of wireless technologies and the intelligent transportation systems, vehicular ad hoc network (VANET) is being gradually applied to the unmanned vehicle, the vehicle enters VANET as a single node to share data such as weather, traffic conditions, driving trajectory, etc. VANET shares the information for all vehicles, which can greatly reduce the traffic accidents caused by a sensor failure; therefore, VANET is a feasible solution to improve the road safety and reduce traffic accidents of the urban traffic.Vehicular ad hoc network mainly consists of certification authority (CA), roadside units (RSUs), and vehicles. CA is mainly responsible for the entire system. RSUs are placed on the roadside, broadcast the service information from CA to vehicles within the communication area, and accept the requesting messages or traffic condition from vehicles. Usually, the communication in VANET can be divided into two types: vehicle-to-vehicle and vehicle-to-infrastructure (V2I), which are built according the basic standard, such as dedicated short range communication. Since these communications are over open channel, the security requirements play an important role. 1-3
