Setting the authentication key for Encrypted Wavelength
The network cards for a Lumen® Encrypted Wavelength Service use an authentication key to authenticate each other every time they negotiate a new crypto session key. You can update the shared authentication key for a given card pair as needed (or according to your organization's security policies). You also need to update the shared authentication key after a network outage or fiber cut.
