The primary duties of the doctoral student position are to perform research and teaching within the computer security area. The research is devoted to researching security for dynamic resource allocation in next-generation mobile networks. Dynamic task execution in future networks will require careful verification of target resources and new principles and protocols for execution target verification are needed. In addition, different protected execution environments for dynamic execution, such as Intel TDX and AMD SEV, have different isolation properties and side channel risks. Side channel attacks on dynamically allocated confidential tasks are within the research scope of the positions. Furthermore, the resource allocation functions can be subject to attacks, and identifying attacks and countermeasures is expected to be studied. The research method will be a combination of system studies, simulations, and experimental research. The research project is a collaboration with Linköping University.

We are seeking to recruit a researcher for an interdisciplinary project on notions of "explainability" in the context of side channel evaluations (considering technical approaches used in both FIPS style as well as CC style evaluations).

The project will run up to three years. It will require a mix of technical skills (we wish to propose and evaluate novel approaches to gather evidence for/against security of implementations given access to side channels) as well as an interest in developing social science research methodologies (we plan to engage with evaluation labs but also vendors to research useful notions of "explainable leakage").

The project will be co-supervised by Prof. Elisabeth Oswald and Prof. Katharina Kinder-Kurlanda; both situated in the interdisciplinary Digital Age Research Centre at the University of Klagenfurt (Austria).

We seek applicants with a mathematical/technical background. For applicants wishing to pursue a PhD, we expect that they have done a MSc/Bsc thesis on side channels/faults with a practical focus. For applicants who already possess a PhD, we expect a strong track record in applied cryptography with some publications in the area of side channels/faults in top venues.

The post holder will be expected to work in Klagenfurt (Austria), and to be able to do short term visits to evaluation labs/vendors throughout Europe.

In order to apply, please send a short CV, including your scientific outputs (e.g. papers, talks, seminars, open source artefacts, etc.), as a single pdf file to Elisabeth.Oswald@aau.at. If you have questions, or wish to discuss informally, please contact Elisabeth Oswald.

Confidential Inference and Explainability: Toward Self-Diagnosis via Imaging

This PhD topic aims to jointly address privacy and explainability of decisions obtained through image analysis using a neural network. In the context of a classification task performed on a remote server, the goal is to develop approaches that ensure the confidentiality of the explanation as well as that of the input (and output) data. Preserving the privacy of data while ensuring the transparency of the model is a crucial challenge, particularly in domains such as healthcare. The objective aligns with the emerging regulatory framework on AI at the European level (AI Act). While these issues are the subject of significant research individually - whether in applied cryptography or machine learning - the combination of explainability under privacy constraints represents a new research problem. The project will seek to identify local explainability methods based on visual information or concepts that can be adapted to a privacy-preserving mode. Confidentiality may be approached through secure multi-party computation and/or homomorphic encryption. Thanks to a collaboration with the Saint-Etienne University Hospital (France), it will be possible to fine-tune the secure AI system and conduct supervised experiments on health data, aimed at enabling self-diagnosis. The experimentation may also extend to ethical and legal dimensions, through a partnership with the University of Ottawa.

PhD Location: Laboratoire Hubert Curien (LabHC), Université Jean Monnet, Saint-Etienne, France (regular meetings at the CITI Laboratory, INSA Lyon, Villeurbanne, France).

Starting date: 01/10/2025.

Expected profile: Candidates holding a degree from an engineering school or a Master 2 from a university in applied mathematics or computer science, with training in cryptography and machine learning, and proficiency in a programming language and one or more reference development libraries in one of these fields.
