Year 4 Student - 2020 Intake – Cohort 2 I’m from a mathematics and software engineering background, with an integrated masters from the University of Warwick (MMATH). I’m interested in aspects of both theoretical and applied cryptography, particularly post-quantum. My research project, supervised by Dr. Chloe Martindale, contributes to the cryptanalysis of isogeny-based post-quantum cryptography. My work aims to break the underlying hard problems of SIDH/SIKE, CSIDH, SQISign, and other related schemes, or instead prove their security. I closely follow the progress of NIST’s post-quantum standardization efforts. Additionally, I have experience working with both start-ups and enterprise on a range of topics including confidential computing, blockchain, privacy-preserving techniques, and machine learning. |

Cryptanalysis of Isogeny-Based Post-Quantum Cryptography Large-scale universal quantum computers could emerge anywhere within the next 10 to 30 years, threatening to break public-key cryptography in use today. Progress is being made to establish new post-quantum secure cryptographic standards. This project will contribute to the cryptanalysis of these new schemes, initially focusing on isogeny-based schemes, by studying the underlying hard problems mathematically. Results will feature new attacks or proofs of security against them, considering attack feasibility and potential mitigations. Discoveries made could inform standardisation efforts, and protocol design. Supervisors: Dr Chloe Martindale (Bristol) and Dr Jonathan Bober (Bristol) |
