Sabine Oechsner

I am a Postdoc in the Cryptography and Security group at Aarhus University, Denmark, hosted by Jesper Buus Nielsen. Previously, I was a PhD student in the Cryptography and Security group at Aarhus University under the supervision of Ivan Damgård. I hold an M.Sc. in Computer Science from Karlsruhe Institute of Technology, Germany.

In Fall 2017, I was a long-term visitor at NTT Secure Platform Laboratories, and in Spring 2018 at IDC Herzliya, visiting Elette Boyle.



I study cryptography and its intersection with formal methods. I am particularly interested in making the two worlds meet in what I believe is the right way: Instead of merely reproducing existing cryptographic proofs with tool support, my goal is to use formal verification as an opportunity to understand how to write better proofs with high assurance, both on paper and in a machine-checkable way. My current focus is on secure computation and similar protocols. I also study the security of secure computation protocols in general.
During my PhD, I worked on the design of efficient privacy-preserving cryptographic primitives, in particular zero-knowledge proofs and ring signatures.



Selected Talks

Aarhus Crypto Seminar

In 2019 and 2020, I organized the weekly seminar of the Cryptography group at Aarhus University. Here is the list of talks during that time.

How to pronounce my last name

The combination OE is an old spelling of the German letter Ö. The pronounciation is similar to the Scandinavian Ø or the French Œ, or the vowel in the English word learn. If you are in doubt, use O instead. The CHS in the middle of my name is pronounced like X or KS in English.
