Context Our team develops pre-silicon analysis tools to: 1) identify exploitable vulnerabilities at the software level based on these interactions between a software and a microarchitecture, or 2) formally prove the security, for a given attacker model, of a system embedding hardware/software countermeasures against fault injections. These tools implement a methodology that has shown to be successful to find microarchitectural vulnerabilities and/or prove the robustness, for a given fault model, of various RISC-V based processors [1]. For instance, we have formally proven the security of OpenTitan's processor to single bit-flip injections [2].

In this PhD trajectory you will be exploring ways and developing protocols and primitives that enhance the security, functionality, and efficiency of secure computation technologies (e.g., multiparty computation – MPC), when designed for particular application scenarios, such as private machine learning use-cases.

In this 4-year PhD trajectory, you are expected to:

Conduct original and novel research in the field of Secure Computation Technologies;

Design novel protocols for privacy-preserving (machine learning) applications;

Publish and present scientific articles at international journals and conferences;

COSIC is looking for a motivated researcher who fit into the following profile: PhD candidate to work on Hardware implementations secured against physical attacks.

Job Description : The position is funded by Flemish Research Funds (FWO). The PhD candidate will work in collaboration with the research group of Prof. Amir Moradi from University of Darmstadt. The research program is defined in a joint research project jointly funded by FWO (Belgium) and DFG (Germany). The title of the project is MatSec – Maturing Physical Security Models in Realistic Scenarios. The PIs of the project in COSIC are Dr. Svetla Nikova and Prof. Vincent Rijmen.

Security models for side-channel analysis and combined attacks for HW implementations exist, but they often make unrealistic assumptions or are inaccurate in modeling physical effects. This results in countermeasures that are either overdesigned, unnecessarily increasing the costs, or still vulnerable to attacks when deployed. The main objective of this project is to provide security models that accurately abstract attacks against cryptographically secured physical devices and that allow for the creation of efficient countermeasures on hardware guaranteeing security in practice.

We are looking for people to work on the following topics: (1) Realistic side-channel models capturing the circuit’s real behavior and achieving a balance between security and efficiency and providing improved countermeasures. (2) Security models and randomness generation: to develop procedures for constructing masked HW/SW implementations with low randomness requirements (3) Combined security models extending known fault/combined adversaries.

Specific Skills Required: For the PhD position: The candidates should hold a master’s degree in Engineering, Mathematics or Computer Science with very good grades, very good knowledge and experience with programing with C/C++ and Verilog/VHDL. Preferably to have passed courses in Cryptography and/or Computer Security.

Who we are: IOG is a technology company focused on blockchain research and development. We are renowned for our scientific approach to blockchain development, emphasizing peer-reviewed research and formal methods to ensure security, scalability, and sustainability. Our projects include the Cardano blockchain, as well as other products in the areas of decentralized finance (DeFi), governance, and identity management, aiming to advance the capabilities and adoption of blockchain and Web3 technology globally.

What the role involves: As a Research Fellow at IOG, you will be responsible for conducting high-quality research, combining your well-developed research skills with a passion for collaborating in innovative research projects. We are looking for someone who is interested in blockchain technologies specifically to conduct research on post-quantum cryptographic solutions for enhancing the security and scalability of decentralized ledger technologies, and potentially harnessing quantum computation to develop novel, future-proof cryptographic protocols. You will join our team of research fellows contributing directly to our diverse development efforts.

Further information: For additional information as well as submitting your application, follow the link in the ad title.

The research group for Cryptographic Protocols located at the University of Luxembourg is looking for one PostDoc as well as one PhD student working on cryptographic primitives and protocols enabling privacy, accountability, and transparency.

A background in post-quantum cryptography and secure multi-party computation is expected, demonstrated by corresponding publications for the PostDoc or successfully attended courses or a master’s thesis on the subject for the PhD student.

The candidates will be based at the University of Luxembourg but also profit from regular visits at the KASTEL Security Research Labs at KIT, Germany. Their research will be dealing with the design and implementation of privacy-enhancing cryptographic protocols in the scope of the EU Q-FENCE project (https://www.uni.lu/fstm-en/research-projects/q-fence/).

If you are interested in joining our group, please send an email including your CV, transcripts, and two references to andy.rupp@uni.lu. The starting date for both positions is November 2025. Your application will be considered promptly.

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.
