Abstract

See full text

Communication information transmitted in the broadband communication system may be in a packet format and secured using encryption techniques, for example encryption software, including a means for providing an initial security key and updated security keys to the various pieces of communication equipment located throughout the broadband communication system. When communication equipment, for example a gateway, is first registered with, for example, an IP central station, the IP central station assigns an initial encryption key to the gateway that is assigned and retained by a server, for example a call manager server, and the gateway (e.g., broadband residential gateway. This initial encryption key may be used to establish a secure two way communication between two pieces of communication equipment as an originating point communication equipment and a terminating point communication equipment.
