Managing Server Keys
Server keys are used to authenticate NTP communications and prevent tampering with NTP timestamps. When
using authentication, both the local and remote servers must share the same key and key identifier. Packets sent
to and received from the server/peer include authentication fields encrpyted using the key.
The following sections describe how to configure and manage server keys:
•
Section 5.12.13.1, "Viewing a List of Server Keys"
•
Section 5.12.13.2, "Adding a Server Key"
•
Section 5.12.13.3, "Deleting a Server Key"
