Our Christiane Kuhn winning the best paper award at PETS 2019

Our Christiane Kuhn, scholar in the research training group RoSI, wins this year's Best Paper Award at the top privacy conference PETS 2019. She is awarded for her presentation and our paper "On Privacy Notions in Anonymous Communications", which is a collaboration of Christiane, Martin Beck, Stefan Schiffner, Eduard Jorswieck, and Thorsten Strufe.
The paper aims to formalize and directly compare the different privacy goals that TOR, ANON, DC Networks, and similar anonymous communication systems claim to, and actually achieve. It integrates both differential privacy-based formalizations, like Anoa, and game-based formalizations. Both previously have been hard to compare. It shows that simple security goals, like "sender anonymity", have been interpreted entirely different by various systems and analysis methods, and rigorously defines an entire hierarchy of notions that can be achieved. The paper has been commended for its strict formalization of privacy goals as notions, and for its comprehensive and rigorous comparison of the different privacy notions by the awards committee. It was filling a methodical gap in literature and facilitated the simple formalization and actual evaluation of the privacy that different systems actually provided.
PETS, the Privacy Enhancing Technologies Symposium, is the primary conference for practical privacy. It was first held in 2000, and all relevant contributions towards anonymity and privacy enhancing technologies have been published, here.
