Patent number: 9712786Abstract: 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.Type: GrantFiled: April 21, 2015Date of Patent: July 18, 2017Assignee: Syphermedia International, Inc.Inventors: Ronald P. Cocchi, Gregory J. Gagnon, Dennis R. Flaharty
