Post-Quantum

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.

More efficient post-quantum KEMTLS with pre-distributed public keys
We make KEMTLS more efficient in scenarios where the client already has the server’s long-term public key, for example through caching or because it’s pre-installed.
