Abstract: Described herein are systems and methods for hardware enforcement of hardware functionality in a television receiver. An activation message containing an activation code for a specific hardware component within the television receiver can be transmitted from a television service provider system to a television receiver having an associated smart card. The smart card can decrypt the activation message, security check the activation message, confirm the activation message is intended for the television receiver, encrypt the activation message with a local key, and transmit the activation message to a security processor on the television receiver. The security processor can decrypt the activation message, security check the activation message to ensure it is from the smart card and has not been tampered with, and enable the hardware component within the television receiver based on the activation code within the activation message.

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.
