Welcome to the Safety-Security-Interaction Group!

The Safety-Security-Interaction group is concerned with the development of theoretically sound technologies for maintaining the security of IT systems in the context of safety-critical systems and the Internet of Things. The focus is on the development of security solutions that are tailored to the context-specific conditions and that take into account various types of user-interaction as well as the functional safety of the to-be-protected systems.

We are looking for motivated university graduates who would like to support our group and who are interested in doing a PhD with us (» job vacancies). If you'd like to know more, then please get in touch!

Our new approach to protect machine learning models from membership inference attacks got accepted at ACM AISec 2022!

Our paper „Repeated Knowledge Distillation with Confidence Masking to Mitigate Membership Inference Attacks” got accepted at ACM AISec 2022! In the paper, we describe a novel approach to protect machine learning models from membership inference attacks. Concretely, we combine the known defence mechanism of "knowledge distillation" with the masking of confidence scores. Our approach is much more flexible than existing defence mechanisms as it allows for the fine-tuning of parameters and as such can be used to achieve a tailored trade-off between the accuracy of the models and the attack protection.
