I concur with John's suggestion. This is how satellite TV providers do it. They allow anyone with a dish to subscribe but only send out keys to authorized boxes.
You can do this with a combo of PUB/SUB and a ROUTER/DEALER combo. See http://zguide.zeromq.org/page:all#Getting-an-Out-of-band-Snapshot So before subscribing, a client would identify itself to the Router socket and recieve keys for the topics it wants to subscribe to.
