Dr. Andy Rupp studied Computer Science at Saarland University where he did his Diploma Thesis in the field of Network Security with Prof. Anja Feldmann. In 2008, he received his PhD degree in the area of Applied and Theoretical Cryptography under the supervision of Prof. Christof Paar at the Horst-Görtz Institute of IT-Security. After a period as Postdoctoral Researcher and Security Engineer both in Academia as well as Industry (UMass Amherst, TU Darmstadt, KIT, AGT International), he was appointed as head of the independent Junior Research Group "CyPhyCrypt" at the Karlsruhe Institute of Technology. Andy's research aims at bridging the gap between novel cryptographic theory on the one hand and security and privacy mechanisms suitable for real-world application scenarios such as Mobile Payments, Smart Traffic, etc. To this end, he develops dedicated security models, crypto primitives, and protocol building blocks which are then composed very carefully to obtain provably secure, yet practical systems. His current focus is on Privacy-Preserving Payment Systems.
