PhD in Cryptography

Title: Cryptanalysis of post-quantum hardness assumptions/nStart date: 1 October 2026/nDuration: 3.5 years/nLocation: University of Surrey, Surrey, United Kingdom/nFunding source: EPSRC/nFunding information: Fully-funded studentship opportunities covering home and international university fees, additional research training, travel funds and UKRI standard rate (£21,805 for 2026/27 academic year)./nProject objective: The objective of this project is to study the concrete security of new cryptographic assumptions proposed to build practical advanced functionality in PQC. The candidate will work with the primary and secondary supervisors to design new attacks targeting the gaps between the new and prior assumptions. The student will also work on new constructions using these assumptions, applying the results of their cryptanalysis to the problem of designing secure systems.
