Abstract
A service node authenticates a service provider network to which it is connected. When the service node is connected between subscriber devices and a network node of the service provider network, the service node issues an authentication request to the network node. The network node responds to the authentication request by transmitting a reply. The service node receives the reply and determines if it indicates the service provider network to which the service node is connected is authentic. These authentication communications can conform to a standard authentication protocol, such as Extensible Authentication Protocol (EAP). If the reply indicates the service provider network is authentic, the service node permits communication between the subscriber devices and the service provider network. If the reply indicates the service provider network is not authentic, the service node blocks such communication.
