Job Description The automotive industry is on the brink of a transformative shift with the rise of Ethernet in zone-based E/E architectures. This evolution not only enables innovative use cases, but also introduces new security challenges. Software-defined networking (SDN), a cornerstone of the Software-defined Vehicle, brings new fundamental requirements, such as dynamic network reconfiguration during runtime and enhanced performance for cryptographic protocols due to increased communication load of ADAS functionalities. It also requires robust security configurations for the network due to the increasing complexity of communication streams. We are seeking a highly motivated PhD candidate with a strong background in embedded security and cryptography. During your assignment, you will conduct in-depth analysis of key agreement protocols, with a particular focus on embedded shared media applications. Also, you develop novel approaches for peer authorization and create tools to efficiently derive security configurations for (automotive) Ethernet networks. Last but not least, you publish, present as well as discuss research findings in top-tier journals and at leading conferences.
