Security and Privacy in Vehicular Ad-hoc Networks

People Involved

Project Description

The great leap forward in wireless communications technology drives the recent advancements of Vehicular Ad hoc NETworks (VANETs). As a key part of the Intelligent Transportation Systems (ITS) framework, VANETs offer active road safety, and traffic efficiency and management. However, they are not free of security and privacy issues by design.

This project aims to address three critical challenges of VANETs. 1) Protecting a vehicle's secret key from being physically stolen: A secret key is required for vehicle authentication and data security. The key is usually stored in Non-Volatile Memory (NVM) but threaten by physical acquisition. 2) Protecting vehicle route information from being leaked to other vehicles, roadside units and even certificate centres: Vehicle’s route information is drivers’ personal data needing to be protected in compliance with GDPR. 3) Protecting traffic trajectories from being exposed to a route planning server: It is critical to balance the usability and privacy of traffic trajectories as it is an important public resource and personal data of drivers. Therefore, the project seeks to overcome these challenges through PUF-based security authentication, as well as privacy protection in route planning and trajectory publishing.

Based on the vital roles of VANETs in life, economy, smart city, and society, the proposed project will promise to generate significant economic and societal impacts once it is completed and adopted by intelligent transportation infrastructure. Additionally, the research outcomes of this project will provide solid theoretical guidance for the further development of security and privacy in the VANETs.
