PhD/Doctoral Studentship - Post-post Quantum Cryptography

Royal Holloway, University of London - Information Security Group

September 2017 - End Date: September 2020

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 www.epsrc.ac.uk/skills/students/help/eligibility). 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.

Applicants should have or be expecting to obtain a first class honours degree or a masters degree in Computer Science, Mathematics, Physics or a closely related subject. The ideal applicant would have some existing knowledge of cryptography and quantum information theory.

Prospective applicants should first make informal enquiries to Prof. Ruediger Schack (r.schack@rhul.ac.uk).
