Post-Quantum TLS with KEMs

We investigate alternate ways to bring TLS into the post-quantum age. Notably, we try to get rid of the expensive signature schemes in the online handshake, by authenticating using only KEMs.

Using (post-quantum) KEMs in TLS 1.3

The new TLS 1.3 standard [1] does not yet provide any support for post-quantum algorithms. In this blog post we’ll be talking about how we could negotiate a post-quantum key exchange using a (post-quantum) Key Encapsulation Mechanism (KEM). In the NIST Standardisation effort [2], many KEMs are currently under consideration.

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.
