International Association
for Cryptologic Research

Join our team as a PhD student in post-quantum cryptography at the Department of Digital Security, Radboud University, The Netherlands. Two open positions within the PQ-HINTS project of Simona Samardjiska funded through the NWO VIDI Talent program, the first one starting in spring 2026, and the second around a year later. The goal of the project is understanding the impact of learning partial information on the private key in post-quantum cryptography. Determining how much leaked information is enough to mount a successful attack is of great importance both in evaluation and protection of post-quantum crypto implementations. You will be working on providing a strong mathematical framework for partial key exposure and using it to improve the efficiency of digital signatures and their implementations while offering strong security guarantees. You will pursue your PhD in a vibrant international research environment. At DiS and Radboud we value diversity, so we particularly encourage candidates with diverse backgrounds, cultures, and perspectives to apply. Requirements: A master degree in mathematics, computer science or a relevant discipline; Solid programming skills and excellent knowledge of algebra and combinatorics; good command of spoken and written English; ability to work in a team. To react to this post, please send your CV and a short motivation to simonas@cs.ru.nl. Don't hesitate to contact me if you have any questions, for example job conditions and environment. The call is open until the positions are filled (expected early 2026).
