Post-quantum TLS experiments
Recently, I have computed the sizes and measured the performance of post-quantum TLS (both PQ key exchange and post-quantum authentication). In these experiments, I have examined combinations of Kyber, Dilithium, Falcon, SPHINCS+-(sf), HQC and (custom versions of) XMSSMT.

hxp 2022 (2023) CTF writeup
After I found myself in a vacation rental with Bas and Joost, we thought it would be fun to have a go at a few of hxp’s 2022 2023 ctf challenges as team #RU (long story relating to Radboud University).

On the Practicality of Post-Quantum TLS using Large-Parameter CSIDH
We propose higher-security parametersets of CSIDH, and present highly-optimized implementations. We measure the performance when using these parameters in TLS, and show that the performance is likely not fast enough to consider using CSIDH with conservative parmeter sets.
