TL;DR: An analysis of the anonymity and unlinkability properties of the method is provided and it is demonstrated that it rapidly reduces the number of vehicles using unique certificates to increase privacy.
Abstract: This paper presents and analyzes a method for enhancing the privacy of vehicles that use the public-key infrastructure (PKI) to secure communications. In particular, it examines the privacy limitations of a PKI system, where certificates are shared among multiple vehicles using a combinatorial certificate scheme. Such a system was implemented in the U.S. Vehicle Infrastructure Integration (VII) proof-of-concept trial to secure vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication and preserve vehicle privacy. The analysis shows that, in low vehicle densities, there is a high probability that a vehicle may have a locally unique certificate that is not shared by other vehicles. Vehicles using unique certificates may be vulnerable to being tracked or identified. This paper proposes a vehicle-based certificate-selection method for enhancing the privacy of vehicle communications. In our method, a vehicle monitors the certificates in use by neighboring vehicles and identifies those certificates that it also possesses. The vehicle then selects a certificate already in use to secure its own communication. This allows a vehicle to ldquoblend inrdquo to its environment but without substantially increasing an attacker's ability to evade exposure. We provide an analysis of the anonymity and unlinkability properties of the method and demonstrate that it rapidly reduces the number of vehicles using unique certificates to increase privacy.

10 Mar 2016TL;DR: It is shown that the proposed distributed solution to block virus spreading over a VANET by initiating a negating spreading process that informs vehicles for the presence of infected nodes can significantly limit the percentage of vehicles infected by the virus.
Abstract: The propagation of software viruses over a vehicular network where vehicles communicate via V2V links can have disastrous effects for the vehicles themselves and the ad hoc network. Here, we propose a simple distributed solution to block virus spreading over a VANET by initiating a negating spreading process that informs vehicles for the presence of infected nodes. We evaluate the proposed approach via simulations using established simulators, and show that the method can significantly limit the percentage of vehicles infected by the virus.

01 Nov 2012TL;DR: This work shows how to exploit vehicles which go around collecting data about their current communication conditions and transfer the data to a central server database and describes the process of establishing such a Connectivity Map including the necessary steps to collect the data and to predict network properties to support vehicular application with additional context information.
Abstract: Vehicular communication using cellular networks is an increasingly important issue and provides additional functionality as well as services with highly topical information. Due to the mobility of vehicles, network coverage or current utilization, frequent changes in the communication properties occur, for example spontaneous significant changes in the available bandwidth. Not all applications can handle such delays or interruptions very well. Moreover, the communication scheduling is not optimal because communication changes come without any prior warning. In many cases it would be helpful if additional knowledge about the future properties is available. In this work we show how to exploit vehicles which go around collecting data about their current communication conditions and transfer the data to a central server database. On the server side we can make predictions about the future connectivity by taking into account various influences and the network dynamic. The vehicles can simultaneously request predictions for their surrounding area and benefit from the historical network data of other vehicles. Finally, the different vehicular applications are provided by such predictions and can be used in different ways. We describe the process of establishing such a Connectivity Map including the necessary steps to collect the data and to predict network properties to support vehicular application with additional context information. Thereby, we also investigate the accuracy of our Connectivity Map in an experimental evaluation scenario.

TL;DR: In this paper, a road-to-vehicle communication system using different frequencies for an outgoing channel from the base station to the mobile station and the reverse incoming channel is utilized while using the communication frame arranging the road tovehicle control/communication slot.
Abstract: PROBLEM TO BE SOLVED: To enable vehicle-to-vehicle communication between mobile stations by using the same frequency by utilizing a road-to-vehicle communication system for performing communication by using different frequencies for outgoing communication from a base station to the mobile station and incoming communication in the reverse direction while using a communication frame arranging a road-to-vehicle control/ communication slot. SOLUTION: The road-to-vehicle communication system using different frequencies for an outgoing channel from the base station to the mobile station and the reverse incoming channel is utilized while using the communication frame arranging the road- to-vehicle control/communication slot. By using the same frequency, the vehicle-to- vehicle control communication slot of incoming channel of slots 1 and 2 is provided with a frame control signal SYNC, link request signal REQ, communication data MDC and delivery confirm signal ACKC. While using these respective signal and data, a present station requests communication to the other station, the reference time of the communication frame is reproduced, the mobile station is identified and communication is enabled between vehicles without overlapping a frame control signal FCMC.
