About the Project

This project aim will design a secure and efficient V2X communication where each party has guarantees on the trustworthiness of their interaction.

Project Description

The project aim is to design a trustworthy, secure and efficient Vehicle-to-anything communication. We can model this as a set of statements/attributes that each party must satisfy. Existing research in this area: attribute-based encryption [DaKW2021], attribute-based signature [DrGM2018] and verifiable credentials [VC-W3C2019, CaDD2017] propose partial solutions, and do not consider simultaneously: complex policies with public, private, self-made, and issued attributes, and trustworthy relationships over the entire network. There are numerous challenges, but the most critical one is on incorporating self-made and private attributes without negatively affecting the trust of the entity using these types of attributes.

Other potential research directions (but not limited to): electronic voting, applied cryptography provable security, privacy-preserving technologies, and formal verification.

How to Apply

It is October 2023 start.

Applications should be submitted via the Computer Science PhD programme page. In place of a research proposal you should upload a document stating the title of the projects (up to 2) that you wish to apply for and the name(s) of the relevant supervisor. You must upload your full CV and any transcripts of previous academic qualifications. You should enter ’Faculty Funded Competition’ under funding type.
