I'm working on a project where I need to scope out NTP with authentication and encryption. Does anyone have some expertise on NTPv4 with this auto-key authentication? I am assuming it follows similar principles as SSH and PGP...?

Yes. NTPv4 uses both symmetric and public key cryptographic algorithms. The scheme of the second (public) is used in SSH and PGP.
