Using Emoji in (pdf)LaTex
I recently wanted to use Emoji in a paper, but I did not want to force my contributors into using LuaLaTeX or XeLaTeX (in which you can just use fancy fonts).

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.

Post-Quantum TLS
Post-Quantum TLS

Ph.D. thesis on post-quantum cryptography in TLS. I investigate current proposals for post-quantum TLS, but more importantly we propose a more efficient TLS handshake that makes use of trade-offs presented by post-quantum cryptographic primitives (which were not as profound in pre-quantum primitives). This more efficient protocol we call KEMTLS. Benchmarks in several different settings for all variants of post-quantum TLS show that KEMTLS is efficient, and we also have an extensive analysis of the security of KEMTLS.

Optimizations and Practicality of High-Security 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.
