摘要： A method and apparatus for providing conditional access to media programs is disclosed. An embodiment of the method comprises the steps of generating a validation message in at least one of the receiver stations, the validation message comprising an answer to a validation query; transmitting the validation message directly from the receiver to the satellite on an always-on backchannel communications link; and receiving the media programs from the satellite only if the validation message matches an expected validation message.

摘要： A method and apparatus for brokering the enablement of the communication of encrypted media programs from a plurality of independent broadcasters to a plurality of receivers is disclosed. The system makes use of a pairing key for each provided service, which is differently encrypted by a pairing server and by the broadcaster providing the service. The encrypted versions of the pairing key are decrypted in a first receiver module using information known to the pairing service but not the broadcaster and in a second receiver module using information known to the broadcaster. The pairing key is used to cryptographically bind the first and second receiver modules.
