Making protocols post-quantum
2022-02-23
Post-quantum key exchange and signature algorithms come with different trade-offs that we’re not used to. How do we handle that when updating protocols, and is this an opportunity to revisit the status quo?...
KEMTLS: Post-quantum TLS without signatures
2021-01-15
The TLS 1.3 protocol has been around for quite some time, but it will be broken once quantum computers arrive. What can we do? In this blog post, we will examine a technique for achieving full post-quantum security for TLS 1.3 in the face of quantum computers: KEMTLS....
