The research area focuses on the security and resilience of modern and future communication infrastructures, addressing the evolving threat landscape in decentralized and high-speed environments. Core activities include the investigation of Zero-Knowledge proofs for authorizing end-to-end encrypted application traffic in the infrastracture layer and the usage of delegated middleboxes to detect anomalous call flows in Function-as-a-Service interactions.
Particular attention is devoted to the use cases relevant for critical sectors such as energy, transport, financial, and health. We also investigate technologies that help companies comply to regulations in those sectors when using edge computing and 5G public and private networks.
We use programmable-data-plane technologies for high-speed networks such as eBPF and NVIDIA Smart NICs, where we develop algorithms for network intrusion detection at wire speed.
Furthermore, the research explores the integration of Quantum Key Distribution (QKD) into existing application and network protocols to ensure long-term cryptographic sovereignty and secure communication against quantum threats.
