Welcome

on the website of the “System Security” group.

About Us

Our research and teaching focuses on system security, network security, applied cryptography, and censorship. Our expertise has contributed significantly to the discovery of critical security vulnerabilities such as DROWN, ROBOT and Efail. We systematically analyse these vulnerabilities and develop test tools to identify and fix them. One example is a tool for flexibly analysing TLS libraries: TLS-Attacker.
