VANET-Based Secure and Privacy-Preserving Navigation

Abstract

IGV² put forward an idea of a real time navigation system that uses the online road information collected by a vehicular ad hoc network (VANET) .The proposed scheme has the advantage of guiding the drivers to desired destinations in a distributed manner using real-time road conditions to compute a better route and at the same time, the information source can be properly authenticated.It presents a framework for vehicle to vehicle communication for effective grouping of vehicles by providing a unique id for every vehicle.The communication between the vehicles is developed with much concern about the privacy and security of the system, for the ease of effective communication between vehicles with a reduced computational overhead.

Existing System

The basic application of a VANET is to allow arbitrary vehicles to broadcast safety messages (e.g., vehicle speed, turning direction, traffic information) to other nearby vehicles (denoted as vehicle-vehicle or V2V communications) and to RSU (denoted as vehicle-infrastructure or V2I communications) regularly such that other vehicles may adjust their traveling routes and RSUs may inform the traffic control center to adjust traffic lights for avoiding possible traffic congestion. As such, a VANET can also be interpreted as a sensor network because the traffic control center or some other central servers can collect lots of useful information about road conditions from vehicles. It is natural to investigate how to utilize the collected real-time road conditions to provide useful applications. Communication messages in vehicular ad hoc networks (VANET) can be used to locate and track vehicles. While tracking can be beneficial for vehicle navigation, it can also lead to threats on location privacy of vehicle user. The problem of mitigating unauthorized tracking of vehicles based on their broadcast communications is addressed, to enhance the user location privacy in VANET. Compared to other mobile networks, VANET exhibits unique characteristics in terms of vehicular mobility constraints, application requirements such as a safety message broadcast period, and vehicular network connectivity.

Proposed System

We propose a new application VANET based secure and privacy-preserving navigation (VSPN), which makes use of the collected data to provide navigation service to drivers. Based on the destination and the current location of the driver (the query), the system can automatically search for a route that yields minimum travelling delay in a distributed manner using the online information of the road condition. In addition of driving guidance, the navigation results can also be used for other purposes. One common approach to resolve possible privacy leakage is to use a different authenticable, but unrelated pseudo identity to communicate with a different RSU. Thus, collecting all messages between a vehicle and all RSUs cannot link the messages together to reconstruct the driving routes or analyze the driving habit of a driver. However, to protect the system.
