Better key negotiations

There exists a secure protocol(Diffie-Hellman) with 2 modular
exponentiation operations for negotiating a key with no
authentication. There exists a secure protocol(SPEKE, SRP, EKE..)
with 2 exponentiations for negotiating a key with mutual
authentication. Doesn't this suggest the existence of a 2
exponentiation protocol for authenticating only one side? Does one
exist? It would be an improvement over what's now used with three
exponentiations by the server.
