We are based on the work of Hülsing, Ning, Zimmermann, Weber and Schwabe and in contact with the group. I havn't heard about kuedlki; the slides seem to refer to a reimplementation of the 2020 paper and the go implementation has been stale for two years. They also seem to use a tweaked krystals implementation which I would not trust. The link to the blog post they refer to dis dead.

The Rosenpass protocol builds on the 2020 paper but also adds security against state disruption attacks (CVE-2021-46873). The implementation is actively maintained, written un Rust not in go. We use Classic McEliece and Kyber from the OQS library.
