PQ TLS and WebPKI (or: Are we PQ yet?)
In deze presentatie vertel ik over TLS en hoe het op dit moment gaat met de transitie naar post-quantum cryptografie. Post-quantum key exchange wordt al uitgerold, maar …
Post-Quantum TLS
I gave a guest lecture on TLS and the challenges and ongoing efforts to make it work with post-quantum primitives.
TLS: Are we PQ yet?
The TLS protocol (famous for `https://`) is perhaps the most-used cryptographic protocol. As such, it is extremely important that it gets migrated to post-quantum cryptography. …
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 …

Post-Quantum TLS
I gave an overview of the challenges for transitioning TLS to PQC, and highlighted a number of proposals to mitigate the impact of large post-quantum signatures.
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 …
Invited Lecture: TLS and Post-Quantum (Applied Cryptography, Radboud University)
Invited lecture about TLS, its history and making TLS post quantum. I also discuss KEMTLS.
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.

Implementing and Measuring KEMTLS
KEMTLS (CCS 2020) is a novel alternative to the Transport Layer Security (TLS) handshake that integrates post-quantum algorithms. It uses a key encapsulation mechanism (KEM) for …

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 …
