EAP is a complete shit show. A cursory search shows at least EAP-PSK, EAP-GPSK, EAP-AKA and EAP-AKA' doing essentially the same thing, none of them particularly well. And I suspect you can do substantially the same thing with EAP-TLS and a PSK cipher suite. #EAP #crypto #authentication #KeyAgreement
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.
