Accepted paper at PETS 2020

The work "T0RTT: Non-Interactive Immediate Forward-Secret Single-Pass Circuit Construction" by Kai Gellert (together with Sebastian Lauer, Robert Merget, and Jörg Schwenk from the Ruhr-Universität Bochum and Tobias Handirk from Paderborn University) was accepted for publication in the Proceedings of the Privacy Enhancing Technologies Symposium (PoPETS 2020).

 

The research paper deals with secure communication in the internet, for example via anonymization services such as Tor (Tor Onion Routing). It provides more efficient security against attacks on network nodes.
