Answer by Mark for Why did post-quantum key exchanges go extinct?
As others have mentioned, in lattice-based key exchange the derived secret is a function of contributions of both parties.In fact, the standardized algorithms are very "diffie-hellman-like" in practice...

I do not see any post-quantum key exchange that creates a shared secret with the contributions of both parties, like in Diffie-Hellman.Actually, in Kyber, the shared secret is a function of...

Principally because NIST did not make key exchanges a necessary part of the process. If we look at the NIST PQC FAQ"NIST provided APIs and security definitions for Public Key encryption, KEM, and...

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...
