<shameless_plug> Check out fwknop, https://www.cipherdyne.org/fwknop/ It's one solution to this problem. Instead of answering with garbage, it allows for keeping the firewall closed/default drop stance. It's port knocking, but with real cryptography instead of just relying on hitting port numbers, and does it with just a single packet. </shameless_plug> Full disclosure: I'm one of the Fwknop devs.

Ssh does a fingerprint verification and establishes a secure channel before it does the password exchange. Avoiding replay attacks can be a challeng as well. Putting strong authentication in a single packet is deceptively nontrivial. It can be done, but at that point you'd be reimplementing Fwknopd. Additionally, Fwknop can protect more than just ssh, and do fancy things like providing access to a machine without a public IP address.
