The NTP client of DES-7200 supports encrypted communication with the NTP
server by means of key encryption.
There are two steps to configure the NTP client to communicate with the
server by means of encryption:

Step 1, Authenticate the NTP client and configure the k
Step 2, Configure the trusted key for the NTP server.
To initiate the encrypted communication with the NTP server, you need to set
authentication key for the NTP server in addition to perfomring Step 1.
By default, the NTP client does not use the global security authentication
mechanism. Without this mechanism, the communication will not be encrypted.
However, enabling the global security authentication does not mean that the
encryption is used to im
and the NTP client. You need to configure other keys globally and an encryption
key for the NTP server.
