description	An information access control system and method which prevents unauthorized access from accessing the information. The apparatus includes a set top box (100) which receives the information from a broadcast stream or recorded medium, or other source and a conditional access module. The set top box (100) is paired with the conditional access module (400) such that they have a shared secret key which is used to send communications to each other. A pirate attempting unauthorized access does not have the shared secret key and thus can not receive the communications. The apparatus and method further require that the set top box (100) and the conditional access module (400) follow one of a plurality of protocols in communicating with each other. A pirate attempting unauthorized access will not able to follow the protocols.
