And this is all joined together into a page where an X25519 key exchange for TLS is explained: «Hands-on: X25519 Key Exchange: Let's exchange a secret to start a secure conversation.»

Excellent stuff anyone interested in #TLS and/or #ECC should always have handy. Wow!

Matthew Green's got a great blog post up talking about how Schnorr signature schemes and identification schemes (aka key agreement) work: https://blog.cryptographyengineering.com/2023/10/06/to-schnorr-and-beyond-part-1/

Part 2 is going to talk about Dilithium, one of my favourites from NIST's post-quantum cryptography competition.

To Schnorr and beyond (Part 1)

Warning: extremely wonky cryptography post. Also, possibly stupid and bound for nowhere. One of the hardest problems in applied cryptography (and perhaps all of computer science!) is explaining why…

Why post-quantum key exchanges went extinct?

On July 5, 2022, NIST chooses one KEM (Key Encapsulation Mechanism) as a PQC standard and 4 KEMs as four-round candidates. Why aren't there any key exchanges? Similarly, KEMs are usually studied in...

A good article on post-quantum cryptography (featuring Kyber and Dilithium, along with explanations of other promising schemes).

NIST’s pleasant post-quantum surprise

On Tuesday, the US National Institute of Standards and Technology (NIST) announced which post-quantum cryptography they will standardize. We were already drafting this post with an educated guess on the choice NIST would make.

ECDH or DH sharing using onion routing

I have come up with a new ECDH sharing method, where I give the common key to dozens of people in advance and then randomly select about 8 people to share the ECDH with whom I want to talk by relay...
