PhD positions in cryptographic design and engineering
Radboud University, Nijmegen, The Netherlands
We have multiple open positions for PhD students in the area of symmetric and post-quantum cryptography in the Digital Security group at Radboud University in Nijmegen. The positions cover different topics, ranging from the provable security of modes of use, design of primitives supported by cryptanalysis, post-quantum algorithms and implementations, and protection against implementation attacks based on power, electromagnetic side channel analysis, and fault attacks. For the symmetric crypto topic, we focus on cryptography based on permutations as in the sponge, duplex and farfalle constructions, especially suited for low energy consumption. For the post-quantum cryptography position, a suggestion is to work on isogeny-based crypto but this can be discussed based on a candidate’s background.

The Digital Security Group of Radboud University is one of the leading groups in computer security in The Netherlands and Europe, and one of the pioneers in permutation-based crypto and corresponding leakage-resilient modes.

The successful candidate should ideally have a master in Computer Science, Mathematics, or Electrical engineering. Applications will be considered until the positions are filled.

To apply, please send the following documents to dis-secr (at), with the subject "PhD position in cryptography":
- a motivation letter
- your cv
- your master diploma certificate (scanned)
- transcript of the courses you took (including grades)
- up to 3 references

To enquire about the positions you can contact: Joan Daemen, joan (at), Lejla Batina, lejla (at), and Bart Mennink, b.mennink (at)
