Welcome to the webpage of the System Security research group

Our research focuses on system security, network security, and applied cryptography. Our know-how made major cont­ri­bu­ti­ons to the dis­co­very of critical se­cu­ri­ty flaws like DROWN, ROBOT, and Efail. We sys­te­ma­ti­cal­ly ana­ly­ze these vul­nerabi­li­ties and de­ve­lop tes­ting tools to iden­ti­fy and fix them. One example is a tool for flexible analyses of TLS libraries: TLS-Attacker.
