International Association
for Cryptologic Research

We are looking for a bright, ambitious, and motivated PhD student to join the cryptography group in the Cybersecurity Engineering Section at DTU Compute in the Copenhagen region of Denmark. The 3-year PhD position will preferably start on 1 November 2024 (or according to mutual agreement). The goal of the PhD project is to improve the state of threshold post-quantum cryptography. You will join the growing cryptography team at DTU and be able to work with researchers in- and outside of the Copenhagen region and Denmark.

Responsibilities and qualifications
Your main task will be to design new threshold cryptographic algorithms with post-quantum security.
You will investigate distributed alternatives to existing post-quantum algorithms such as Dilithium, Falcon and Picnic, and the long-term security of threshold cryptography, in particular with respect to proactive and post-quantum security. To succeed in this research effort, you will gain familiarity with:

• post-quantum cryptographic primitives such as signatures or OPRFs
• threshold cryptographic techniques such as secret sharing and multiparty computation
• cryptographic foundations of post-quantum cryptography such as lattices, MPC-in-the-head, FHE and similar tools

In addition to the research project, you will conduct a limited amount of small-class teaching during your PhD period.

As formal qualification, you must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. Furthermore, to ensure a smooth start into the project, it is preferable that you have previous experience with either threshold or post-quantum cryptography.

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years. The position is a full-time position and the starting date is 1 November 2024 (or according to mutual agreement).
