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.
