Open standard conditional access system
First Claim
1. A system for implementing a communication protocol between devices in a home and security system servers in a cable network for delivering both IP data and non-IP data content, comprising:
- means for maintaining a communication protocol between devices in a home and security system servers in a cable network for the exchange of IP data; and
means, using said communication protocol, for creating a communication session between said devices in a home and said security system servers in a cable network for exchanging non-IP data content.

Abstract
The present open standard conditional access system uses an open standard protocol for authenticating devices, selectively enabling services, and revoking service on cable and satellite content distribution networks. This system uses a two-way communication protocol between devices in the home and security system servers in the cable network. This allows for security information to be sent only to those devices that need the security information. A two-way communication protocol also allows the end device to request security information instead of waiting for it to be broadcast as in a one-way protocol. The present open standard conditional access system uses the security system already present in most DOCSIS cable modems to protect both IP data and MPEG content.
