INTERACTIVE PROTOCOL FOR REMOTE MANAGEMENT OF ACCESS CONTROL TO SCRAMBLED DATA |
摘要 |
The invention concerns a protocol for remote management, from a broadcasting center (E), of access control to scrambled data, through a descrambling terminal (T) and an access control card or module provided with a security processor (PS). It consists in transmitting (A) from the broadcasting center (E) to at least a receiver set (PR) or the security processor (PS) a control message including input template fields, control applicative data, digital signature, and in subjecting (B) the exchange of action instructions and the replies to said action instructions, between the terminal (T) and the security processor (PS), to a local security protocol inhibiting any local viewing at the security processor (PS)/terminal (T). The invention is applicable to management of broadcasting or distribution of scrambled or encrypted data. |
