Design of security functionality for V2X networks

The rapid development of edge computing, internet-of-things (IoT), as well as 5G communication stimulates the progress of vehicular ad hoc networks (VANET). In the upcoming era of Intelligent Mobility (IMob), when every single vehicle has an independent and powerful computation capacity, it is crucial to guarantee secure and reliable information exchange in vehicle-to-everything (V2X) communication.

Regardless of the automobile manufacturer’s preferred communication technology – C-V2X or DSRC - secure data sharing should be a serious consideration.

This project aims to tackle the security and privacy challenges of the V2X communication from three different aspects by implementing block-chain and other cryptographic theories. First, to explore the block-chain technique with the characteristics of immutability and verifiability, based on which, a novel authenticaton method that can be constructed. Secondly, combining block-chain and differential privacy organically to address the driving data sharing and information dissemination security needs. Finally, to develop a trust model for the platoon scenario, where communication security can be guaranteed.

To meet the security demands in V2X scenarios, the research will analyze the potential risks in the cyberspace of VANETs. In this project, a framework, consisting of security schemes from different aspects, will be designed to tackle security and privacy issues in data sharing and ridesharing for intelligent mobility.

The outcome of this project will be a block-chain based secure communication prototype system which will have two types of potential economic impacts – direct and indirect.

Firstly, with an increasing number of vehicles on the road, traffic congestion becomes a serious drawback which affects the global economy because it has been an indiscriminate phenomenon all around the world. To solve this problem, intelligent mobility has been considered, in which secure and reliable V2X communication is the most crucial aspect. It is predicted to be a huge market.

Lastly, without privacy protection, neither the reliability of V2X communication nor the privacy of an individual can be guaranteed. The situation may exacerbate in the case of autonomous driving, where vicious misleading information may result in a serious traffic disaster. As such, this research focuses on prevention of possible potential hazards and attempts to develop corresponding solutions.
