authentication-mode md5 value: Uses the MD5 algorithm for key authentication.
simple: Sets a plaintext authentication key.

Usage guidelines
In a network where there is a high security demand, the NTP authentication feature must be enabled for
a system running NTP. This feature enhances the network security by using client-server key authentication,
which prohibits a client from synchronizing to a device that has failed the authentication.
After you specify an NTP authentication key, use the ntp-service reliable authentication-keyid command
to configure the key as a trusted key. The key automatically changes to untrusted after you delete the key.
In this case, you do not need to execute the undo ntp-service reliable authentication-keyid command.
You can set up to 128 keys by executing the command.
The authentication key, set in either plain text or cipher text, is saved to the configuration file in cipher
text.
Examples
# Set a plaintext MD5 authentication key, with the key ID of 10 and key value of BetterKey.
<Sysname> system-view
[Sysname] ntp-service authentication enable
[Sysname] ntp-service authentication-keyid 10 authentication-mode md5 simple BetterKey
