摘要： The invention relates to pairing a slave device with a master device, for example decoders in a conditional access system. There is provided a security module that stores a device state that indicates whether a decoder shall be a master or a slave decoder. There is also provided a method in a conditional access system of providing a device with a device state stored on a security module. It is detected that the security module is in connection with the device and the device state is transferred from the security module to the device. There is further provided a method of pairing a slave device with a master device. The slave device asks the master device to identify itself, the master device returns an identification, and if the slave device has not yet been paired with a master device, it checks the identity of the master device and, if the identity is verified pairs with the master device. There is also provided a first, slave, device for pairing with a second, master, device. The first device comprises an interface for sending an identification command to and receiving an identification message from the master device, and a processor for checking the identity of the second device and pairing the first device with the second device.

摘要： The invention relates to a device for preventing illegal exportation of a content protected by a global copy protection system to a local copy protection system. According to the invention, each content liable to be exported contains a unique identifier and the device comprises a table for storing unique identifiers of all contents that have already been exported through said device. The invention also relates to a method for recording a content received by such a device. This method comprises the steps consisting, if the copy is to be made for a local copy protection system, in checking whether the unique identifier of said content is contained in the table of said device; and should said checking be positive, in preventing the recording; andshould said checking be negative, in recording the content and storing said unique identifier in said table.

摘要： The invention relates to a method to verify that data received by a receiver has been sent by a transmitter authorized by a trusted third party, the transmitter and the receiver being connected to a digital network. An identifier is associated with the data sent by the transmitter and, on receipt of the data by the receiver, the receiver generates a random number and diffuses the same on the network. The transmitter that receives the random number calculates a response by applying a first function to the random number and to the identifier, and sends the response to the receiver which verifies the response received by applying a second function to the response received, the random number and the identifier. The first function is delivered first to the transmitter by the trusted third party. The second function is a function for checking the result of the first function which is delivered first to the receiver by the trusted third party.

摘要： A symmetric key management process in a communication network comprising a source device furnished with a source of data to be broadcast over the network and at least one receiver device intended to receive the broadcast data. The process comprises: determining and securely transmitting a first symmetric key to a receiver device; the receiver device encrypting the first symmetric key using a second symmetric key and transmitting it to the source device; and the source device recovering and storing it. Before transmitting the data to at least one reception device, the source device encrypts these data with the aid of the first symmetric key, then it transmits these encrypted data, accompanied by the first encrypted symmetric key, to at least one receiver device. The receiver device decrypts the first symmetric key with the aid of the second key which it possesses, then it decrypts the encrypted data with the aid of the first symmetric key thus recovered.

摘要： To transmit digital data representing a content from a source to a receiver through a digital communication channel, the data being scrambled by at least one control word, the method includes the following steps. The source generates an encryption key which it stores temporarily. It encrypts the control word with the encryption key and transmits to the receiver the scrambled digital data and the encrypted control word, the latter being transmitted through an encrypted communication channel. The receiver then performs an operation of authentication of the source. When the source is authenticated by the receiver, it transmits the encryption key to it. The receiver then decrypts the control word and descrambles the data so as to present them to a user. The encryption key is then erased from the memories of the source and the receiver when the content has been entirely transmitted.

摘要： The invention relates to a method for controlling digital rights of the “Play N times” type for a digital audio and/or video content, referred to as controlled content, the controlled content being consumed by a consumer on a consuming device or on another device delegating the controlling of these rights to the consuming device. According to this method, charging of one additional usage is inhibited in at least one of the following cases where: the consumer momentarily consumes another content, on the same device where the controlled content is consumed, and then returns to the controlled content; the consumer effects a pause in the usage of the controlled content; the consumer performs a fast-forward of the controlled content; or the consumer performs a rewind of the controlled content.
