Abstract (en)

[origin: WO0111883A1] An inter-network conditional access system unifies network security and application/content security in a single system to protect a service provider's service and to secure a content provider's content in a multicast network environment. The system includes at least one content provider to provide digital content, and at least one service provider to securely receive the digital content from the at least one content provider and to securely distribute the digital content. The content provider and the service provider may create a relationship of trust between themselves. The system also includes at least one content consumer to securely receive the digital content from the at least one service provider and to securely consume the digital content. The content consumer and the service provider also may create a relationship of trust between themselves.
