摘要： The aim of this invention is to control the change of a security module and deactivate the apparatus in the event of the non-authorized removal or replacement of said module. A protection device for a security module connector is proposed, said connector forming part of an acceptor placed on a printed circuit board and integrated into an apparatus whose functioning, controlled by a processor, depends on the security module connected to the acceptor. The device comprises a first part made up of a label attached in a way to block the security module on the printed circuit board, said label including at least one chip and a first antenna. The device further comprises a second part positioned in the vicinity of the connector, said part including a second antenna of a transducer in communication with the apparatus processor. The chip of the label is able to exchange digital signals by means of the first antenna with the second antenna.

摘要： This invention concerns a safe data exchange method between two devices locally connected to one another. In a preferred embodiment, the first device (10) is a security module containing a first encrypting key, said private key (PAKV) of a pair of asymmetric encrypting keys. The second device is a receiver (11) comprising at least one second encrypting key, said public key (PAKB) of said pair of asymmetric encrypting keys. Furthermore each of the devices comprises a symmetrical key (13). The first device (10) generates a first random number (A), which is encrypted by said private key (PAKV), then transmitted to the second device (11), in which it is decrypted by means of the public key (PAKB). The second device (11) generates a second random number (B), which is encrypted by said public key (PAKB), then transmitted to the first device (10), in which it is decrypted by means of the private key (PAKV). A session key (SK), used for safe data exchange, is generated by a combination of the symmetric key (13) and the random numbers (A, B) generated and received by each of the devices.

摘要： A device for the generation of several light beams is used notably to illuminate light spatial modulation screens with the 16/9 format in color image projectors. The aim is to improve the luminous efficiency. The disclosed generator device has a light source producing a primary beam and two wavelength selective mirrors. The two selective mirrors are illuminated by the primary beam and produce two secondary beams of different wavelengths. On the one hand, the two selective mirrors are placed side by side and intercept different parts of the section of the primary beam. On the other hand, a rear face that is at least partially reflective is positioned opposite the source with respect to the selective mirrors.

摘要： A method to optimize reception of entitlement management messages in a subscriber unit that is part of a Pay-TV system. The subscriber units are set up to a default reception channel for receiving default entitlement management messages such as the ones addressed to all or a group of subscriber units controlled by the management system. When one or a plurality of operating parameters of a specific subscriber unit needs to be modified, the security module sends an information signal to the subscriber unit which switches to a specific reception channel. In this case only specific entitlement management messages, also called positive addressing entitlement management messages, are received for performing the operating parameters modification of the concerned subscriber units. Once the modification is executed, the subscriber unit switches back to the default reception channel to be ready for receiving default entitlement management messages again.
摘要翻译：一种在作为付费电视系统的一部分的用户单元中优化接收授权管理消息的方法。订户单元设置为默认接收信道，用于接收默认授权管理消息，例如寻址到由管理系统控制的全部或一组订户单元的默认授权管理消息。当需要修改特定用户单元的一个或多个操作参数时，安全模块向切换到特定接收信道的用户单元发送信息信号。在这种情况下，仅接收特定授权管理消息（也称为正寻址授权管理消息），以执行相关用户单元的操作参数修改。执行修改后，用户单元切换回默认接收通道，准备再次接收默认授权管理消息。
