Safran VersaSync User Manual page 147

NOTES:
Duplicate key IDs are not permitted. NTP requests received by that do not con-
tain an authenticator containing a valid Key ID and MD5 message digest pair will
be responded to, but no authentication will be performed. An NTP request with
valid authenticators results in a valid NTP response with its own valid authen-
ticator using the same Key ID provided in the NTP request.
You may define the trusted Symmetric Keys that must be entered on both Ver-
saSync, and any network client with which VersaSync is to communicate. Only
those keys for which the "Trusted" box has been checked will appear in the drop-
down menus on the NTP References screen.
