7. Make sure that your Wireless Edge Services xl Module has the proper
certificates. See “Digital Certificates” on page 2-165.
Adding Symmetric Keys. Symmetric key authentication uses a single (sym-
metric) key for encryption and decryption. Because both the sender and the
receiver must know the same key, it is also referred to as shared key cryptog-
raphy. The secure NTP devices use the symmetric key to authenticate their
communications: they only accept packets that have been encrypted with the
shared key.
To set up symmetric keys on the Wireless Edge Services xl Module, first
configure keys and assign them a numeric key ID value. When you configure
NTP neighbors (see “Configuring NTP Neighbors” on page 2-152), you will
specify the symmetric key by entering its numeric key ID.
To add a symmetric key, complete these steps:
1. Select Special Features > Secure NTP. Configure initial settings as described
in “Configuring Secure NTP Options” on page 2-144.
2. Select the Symmetric Keys tab.
