A fully funded PhD/Doctoral Studentship is available at the Information Security Group of Royal Holloway (University of London) in the area of post-quantum cryptography.

The studentship is funded in part by the EPSRC Quantum Communications Hub and in part by Royal Holloway and is subject to EPSRC's eligibility criteria (see The funding will be for a period of 3 years and covers costs of university fees plus a stipend of £16,553 per annum (corresponding to the National Minimum Stipend plus London Allowance).

The ongoing development of quantum-computing technology poses a threat to the security of some widely used cryptographic schemes.

Post-quantum cryptography responds to this threat by designing and analyzing schemes that are immune to attacks by an adversary assumed to be in possession of a quantum computer. The more recent field of post-post quantum cryptography assumes in addition that the adversary has full access to a quantum implementation of the encryption and/or decryption device, which implies that the adversary would be able to carry out a quantum superposition attack. This project will address some of the many open questions in post-post quantum cryptography.

Possible directions for research include the development of formal security models and the cryptanalysis of a variety of cryptographic schemes under quantum superposition attacks. Another potential direction is the analysis of an in-between scenario where the adversary has full quantum-computing capabilities but only limited quantum access to the device, which is gaining importance with the increasing miniaturization of components.
