NTP authentication

Hi,

what's is the function NTP authentication?

For example, I have a router configured as NTP MASTER, so I want that only routers that have the same authentication key can GET time from this server... but in my tests any device can GET time from my NTP MASTER...

If the authentication is used to prevent that invalid time sources can update the time of my device... I will need to configure authentication in my NTP clients?

Re: NTP authentication

Configuring NTP authentication is sometimes tricky. I am sure the following documents will help you understand NTP authentication better.
