You can associate a 
non-existing key with an NTP 
server. To enable NTP 
authentication, you must 
configure the key and specify it 
as a trusted key after 
associating the key with the 
NTP server. 

 

The procedure of configuring NTP authentication on a server is the same as that on a client, and the 

same authentication key must be configured on both the server and client sides.
