Patent ID: 7496764

Claim:
A method for transmitting encrypted data (DT) between a local server (HS) connected to one or several local peripherals, the peripherals having a security module and able to process a plurality of right messages issued by the local server (HS) encrypted data (DT), said local server (HS) includes a security module (SM) in charge of acquiring a right message including a decryption key relative to the encrypted data (DT), first access conditions relating to the local server and second access conditions relating to a peripheral, the method comprising: transmitting the encrypted data (DT) of the local server (HS) towards a the peripheral, extracting from the right message the second access conditions corresponding to the decryption's condition of the encrypted data (DT) part necessary for the decryption of the data (DT) in the peripherals, encrypting by the local server's security module (SM), a second right message including the second access conditions and the decryption key, by a pairing key specific to the couple formed by the security module of the local server and the security module of the peripheral, wherein the first access condition comprises conditions of transmission towards the peripherals, and the security module of the local server restrains the transmission of the second right message depending on the first access conditions, transmitting the encrypted second right message to the local peripheral, decrypting with the help of the pairing key, the second message with the security device of the peripheral, and applying the second access conditions by the peripheral's security module, and if allowed, decrypting the encrypted data (DT) received by the peripheral by the decryption key.
