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.

Post-Quantum TLS without handshake signatures
We present an alternative to TLS 1.3, by authenticating using only Key-Encapsulation Mechanisms. This allows us to get rid of handshake signatures, as post-quantum signature schemes are expensive, both in bytes and computation times.
