It's really strange that this topic gets so less attention.

I am sorry, information is very hard to find on Google. Here are two
links, how to set up authenticated NTP as a client.
https://ntp3.sp.se/howto.html
http://support.ntp.org/bin/view/Support/ConfiguringAutokey

What I have not found yet, is a free, public NTP server, not to speak
about a whole list. Only a few servers in the NTP pool do support it. This
is probable not going to change, if we do not discuss it.
