Abstract
Described herein are systems and methods for securing transmission of content from a smart card in a host television receiver to a client television receiver. The smart card can receive the encrypted content stream from the television service provider, decrypt the content stream with the global network key, identify the client television receiver as the destination of the content stream, generate a unique key specific to the content stream, encrypt the unique key with a local key known to the client television receiver, encrypt the content stream with the unique key, and transmit the encrypted content stream along with the encrypted unique key to the client television receiver. The client television receiver can then receive the encrypted content stream and the encrypted unique key, decrypt the unique key, decrypt the content stream with the unique key, and transmit the content stream to a display device of the client television receiver.
