One-Round authenticated Key Exchange (ORKE) is an established research area, with many prominent protocol constructions like HMQV and Naxos and many slightly different, strong security models. Most constructions combine ephemeral and static Diffie-Hellman Key Exchange (DHKE), in a manner often closely tied to the underlying security model. The authors give a generic construction of ORKE protocols from general assumptions, with security in the standard model and in a strong security model where the attacker is even allowed to learn the randomness or the long-term secret of either party in the target session.
