Secure and Trustworthy Network-Attached System Architectures

Our research group analyzes the technologies that are foundational to the creation of system architectures for complex (and often disparate) workloads without sacrificing safety or security. Research thus includes processor technologies like virtualization and execution of encrypted code (such as cryptographically protected virtual machines or the so-called enclaves), but also algorithms for distributed systems to establish trust relationships between cooperating nodes as well as the integration of platform components that can act as "trust anchors", such as the Trusted Platform Module (TPM) or firmware solutions based on ARM's TrustZone isolated execution environment. Finally, the group also prototypes pure software solutions and improvements to existing system libraries and applications in order to harden them against common attacks. More information regarding each area is available on our Research page.


The research group has been formed in conjunction with the German national metrological institute "Physikalisch-Technische Bundesanstalt" (PTB). It is integrated into PTB as the junior research group 8.55 "secure and trustworthy systems" - more information regarding its PTB-related activities can be found there. Beyond its research activities, the group is teaching one or two courses per semester - the list of current courses can be found here - and offers supervision of Bachelor and Master degree theses. Interested students can find further information here.
