Abstract: 
Onion routing and mix networks have been developed to enable anonymous communication even under surveillance. Those networks remove the relationship between the message and its corresponding sender by forwarding the message over multiple proxies that modify it at each hop. To guarantee that the applied modification sufficiently unlinks the sender and message, formal proof strategies for onion routing and mix networks emerged.

In this talk, Christiane will provide an introduction to the field of provable privacy for onion routing and mix networks leading up to recent findings (IEEE S&P 2020, AsiaCrypt 2021): Multiple "provably private" state-of-the-art protocols, contain vulnerabilities that limit or even completely break their anonymity. Those vulnerabilities should not exist if privacy is proven correctly. Therefore analyzing the used proof strategy to find its flaws and suggest an improved, effective one instead.
