Using lattices/ring-LWE, there is Lattice Cryptography for the Internet (by me), which inherits from Ring-LWE encryption, and has been implemented by Bos et al. with further improvements by Alkim et al. The underlying mechanism is conceptually DH-like, but uses completely different mathematics. We start with a uniformly random $a \in R_q = R/qR$, which can ...

Ed25519 is well-defined and requires you to use SHA-512 as internal hash function along with the twisted Edwards version of Curve25519, hence there's no need for a KAC when it comes to questions about the parameters. As for the integrity of the public key, there's not yet a standard for Ed25519 based certificates so there would be a custom solution needed ...
