摘要

The secure digital word descrambling method has a receiver (8) connected to a computer (9) feeding an application (10) with digital numerical words and software access control (6). A closed system descrambler (4) provides access control to an integrated circuit (7) and an internal table (11) establishes correspondence with identifiant (1d) and access key (CA) descrambling the digital words received, by sending the identifiant to the software access control.
