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 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 comparable software-based solutions, e. g. secure monitors implemented to run in ARM TrustZone. At the same time, the group investigates and develops a new kind of second-factor authentication (2FA) device and works on the corresponding protocols. Finally, the group also prototypes 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 cooperation with the German national metrological institute "Physikalisch-Technische Bundesanstalt" (PTB). Its activities are integrated into the department 9.4 "Metrology for Digital Transformation" [1], where the results and demonstrators of the group are directly applied to further PTB's digitalization efforts in legal and industrial metrology. Beyond its research activities, the group is offering one course per semester, which can be found here [2]. Students interested in writing their Bachelor and Master thesis with us can find further information here [3].
