Dynamic Challenge-Response Authentication

Solstice PPP can be used in conjunction with third-party, dynamic challenge-response authentication products. These products issue a challenge value that requires a response from the user. This response is calculated dynamically based on the challenge value. Note that this is the only authentication method that controls the identity of the user rather than the identity of the client machine.

Solstice PPP uses interactive CHAT scripts, which are discussed in the next section, to support challenge-response authentication.
