摘要： This invention relates to a management method for conditional access data processing by at least two decoders associated to a subscriber. These decoders include activation/deactivation means for conditional access data processing and local communication means structured to allow communication between the subscribers' decoders. This process comprises a reception step, by a first decoder's local communication means (10), of at least one message originating from at least a second decoder (STB) associated to said subscriber. Then, it comprises a step to determine the minimum number of different decoders of said subscriber from which said first decoder must receive messages, and a comparison step between on one hand the number of different decoders from which said first decoder has received a message and on the other hand the minimum number of decoders from which said first decoder must receive a message. Conditional access data processing by said first decoder (STB) is deactivated if the latter has not received messages from the required number of different decoders. The invention also concerns a decoder that allows the implementation of the method according to the invention and characterized in that it includes local communication means (10) structured to transmit messages to other decoders and to receive messages originating from said other decoders, and processing means for messages received by said local communication means (10).

摘要： A method that allows the optimization of the consumption of conditional access content in order to guarantee less vulnerable right messages involves three steps: the selection by the user of a content and the indication of this interest to said management center; the sending of a notification message containing or indicating the access authorisation message shortly before the broadcast of said content and storage of this authorisation message; and the sending of the content itself and the use of the data of the authorisation message in order to access the data of the content. There may be a fourth stage, namely the validation of the authorisation message by the user. This validation is executed in general at the time of the reception of the content or alternatively the user confirms their intention to purchase.

摘要： A method is proposed for creating a secure and authenticated channel between a multimedia processing device and a security module that can be shared between several entities, the data transmitted to one entity not compromising the other entities. The a protection method, for data exchanged between a multimedia processing device including a personal key and a security module managed by a management centre, includes determination of an identifier pertaining to an entity representing a group of multimedia processing devices, calculation of a security key formed by a one-way operation based on the personal key of the multimedia processing device and the entity identifier, and transmission of this security key to the security module connected to the entity. A security key is then formed between the multimedia processing device and the security module, by means of the reception of the entity by the multimedia processing device. The multimedia processing device then calculates the security key by a one-way operation based on the personal key of the multimedia processing device and the entity identifier. Finally, the key is used to secure the data exchanged between the multimedia processing device and the security module.

摘要： The invention concerns a method for providing a plurality of receivers with conditional access to broadcast services using a simplified means for managing the control messages required by such conditional access schemes. The method involves providing all information which will allow a registered receiver having the necessary decryption key to access the services without having any prior rights loaded locally. A management center keeps a register of all subscribed receivers, including a list of services to which the receiver is subscribed, and encrypts the services using control words encrypted by the necessary keys. Control messages comprising the control words for decryption are provided within a special channel to which the receiver has permanent access, the special channel being a different one from channels used for broadcasting audio/video services.
