Method and system for conditional access to a digital content, associated terminal and subscriber device |
| abstract |
The invention relates to a secure method for transmitting a control word between a server (3) and a plurality of processing entities (Ea, Eb, Em) so as to respectively produce and utilize said control word. Preferably such a method is applied to the field of conditional access methods and systems for preventing the fraudulent use of compromised decryption keys resulting from a coalition of pirate hackers. |
