I suppose it was taken from SP800-63 or so.
Anyways, we should define them or replace them with more direct wordings.

Front channel essentially, as you are aware of, is the communication 
through the user agent.
Back channel is the direct communication between the client and the server.

Any volunteer for the definition wordings?
