Abstract

A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. Security boundaries such as conditional access (CA) and/or digital right management (DRM) boundaries associated with the broadband gateway are identified based on security profiles associated with the plurality of devices and/or a service from networks. The identified security boundaries are utilized to determine or negotiate CA information for content access for the service. The received content may be distributed according to the determined CA information and the security profiles of the corresponding devices. The broadband gateway may be automatically and dynamically configured based on the identified security boundaries to secure content distribution to the devices. Content distribution security schemes, for example, super encryption, simul-crypt, IPSec and/or watermarking, may be selected by matching the CA information with corresponding device security profiles.
