Need help in allowing symmetric cryptography[2]

The server that provides the time synchronization must be configured to allow its clients to verify its authenticity using symmetric cryptography[2].

I don't think there is any coding since it is just configuring to allow it.

Much Appreciated!

Thanks for the link. However, i did not see any symmetric cryptography. Is it the same as the configuring NTP?

You agreed not to bump posts when you registered, stop doing it.

Also read the link more carefully. They call it 'authentication'.
