2.3 Authentication Attribute
What is ... Two main methods for authentication are supported in the SpeedTouch™:
 pre-shared key
 certificates
The authentication parameters used for the IKE negotiations are bundled in the
SpeedTouch™ in a descriptor with a symbolic name.
This symbolic descriptor is called the Authentication Attribute, and is encountered
when you configure the SpeedTouch™ via the Command Line Interface.
For pre-shared key authentication, this attribute holds the pre-shared key. For
authentication with certificates it simply indicates the authentication method.
