Project Description

This project aims to study lattice-based attribute-based encryptions (ABE) with enhanced security guarantees, including revocation and traceability. In an ABE system, users’ decryption keys and ciphertexts are associated with descriptive attributes. The decryption keys can decrypt ciphertexts if there is a match between the attributes of the ciphertext and a user’s decryption key. The ABE system requires revocation, meaning the users’ decryption keys can be revoked periodically. Traceability is also necessary for ABE systems, especially in ABE-based commercial applications. For example, a decryption device contains a set of decryption keys being sold on eBay for financial gain. Due to the nature of ABE, no one can track the malicious users who built such a decryption device using their decryption keys.

How to Apply

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.

Funding

The studentship will provide a stipend at UKRI rates (currently £17,668 for 2022/23) and tuition fees for 3.5 years. An additional bursary of £1700 per annum for the duration of the studentship will be offered to exceptional candidates.
