The Cryptography group at University of Vienna is searching for a motivated PhD candidate to join our team. We develop new security definitions which match practical applications, explore complexity-theoretic relations, develop novel, sophisticated proof techniques, and design schemes that provably satisfy strong security guarantees. Hence, strong mathematics skills are advantageous and arguing by formal mathematical proofs is essential.

Besides research (including attendance and presentation at workshops and conferences), the candidate will be involved in a small amount of teaching, according to the university regulations.

The position is fully funded for 4 years with a competitive salary and available from September 2025; the exact starting date is negotiable. For eligibility, an MSc degree in Computer Science or Mathematics (or a related field) is required. Applications must contain all requested documents and be done exclusively through the linked job portal at University of Vienna.

University of Vienna is located centrally and public transport is extraordinarily good. Also internationally, Vienna is very well connected by train, plane and bus. There are several cryptography research groups in and around Vienna and we encourage regular exchange through a joint reading group.

The Jean-Monnet University (UJM) at Saint-Etienne in France is now seeking excellents candidates for tenure-track (Associate Professor) position starting in november 2025.

This is a special position in France, as it is a first 5-year contract, and if the indicators are met the position automatically becomes that of a Full Professor. For 5 years, the person recruited is only required to carry out 64 hours of teaching per year, with dedicated financial resources. It's a research-oriented position in one of Europe's leading hardware security teams (the SESAM team at Laboratoire Hubert Curien).

The objective of this position is to ensure the long-term security of embedded systems by developing countermeasure mechanisms that can defend against sophisticated attacks at the intersection of software and hardware, starting from the design phase. This will result in new protection concepts being proposed that take into account the evolving cyber threat and the complexity of attack paths that exploit vulnerabilities in both software and hardware.

We are therefore looking for excellent candidates with at least 5 years' post-doctoral experience and an excellent list of scientific contributions and publications in the field of hardware security.

I am looking for a PhD student in the 6-year project CAVE, funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) through the Emmy Noether Programme.
