摘要:
An arrangement for secure user authentication includes a computer or telecommunication terminal with a smartcard and a device. The smartcard is adapted to securely store biometric information relating to at least one user and the device is adapted to detect biometric data of users. The smartcard and the device include a radio interface for communicating together and a module for exchanging biometric information between each other. In this way, tampering of the transferred biometric information is difficult. In order to increase the security, one or more of the following measures may be used: a secure communication channel between the device and the smartcard, a direct (preferably short range) communication channel between the device and the smartcard and encryption and decryption of biometric information transferred between the device and the smartcard.

A home electronic apparatus is able to receive a broadcasted communication service and to enjoy it by means of rights information; the rights information allows billing for the enjoyment. A mobile telephone terminal is associated to a subscriber card storing subscriber rights information. According to the method of the present invention, at least the subscriber rights information is transferred from the mobile telephone terminal to the home electronic apparatus when the mobile telephone terminal is in proximity of the home electronic apparatus, the transferred information is stored into the home electronic apparatus, and the broadcasted communication service is received and enjoyed by means of the transferred information.

The present invention relates to a system (10) and method for making electronic circuits comprising elements or elementary circuit blocks which can be implemented either in the form of physical circuits, for instance FPGA, or in the form of firmware, for instance memorised on microprocessor. Thanks to the methodology used to describe the circuit blocks (26a, 26b) and their functional models (21), the system (10) and method allow to execute with a WS (11) and an emulator subsystem (30), in a single integrated environment, both the functional simulation of the model of complex electronic circuit and the emulation of the electronic circuit itself. Moreover, thanks to the characteristics of intrinsic congruence between the circuit blocks (26a, 26b) and their models (21), the emulation of the complex electronic circuit can be effected using alternatively circuit blocks implemented on the emulator subsystem either in the form of hardware (26a) or in the form of firmware (26b).

A method of exchanging data within a direct memory access (DMA) arrangement including a plurality of IP blocks (A, B, C) includes the step of associating with the IP blocks (A, B, C) respective DMA modules (IDMA A, IDMA B, IDMA C), each DMA module including an input buffer (11A, 11B, 11C) and an output buffer (12A, 12B, 12C). The DMA modules (IDMA A, IDMA B, IDMA C) are coupled over a data transfer facility (BUS) in a chain arrangement wherein each DMA module has at least one of its output buffer (12A, 12B) coupled to the input buffer (11B, 11C) of another DMA module downstream in the chain and its input buffer (11B, 11C) coupled to the output buffer (12A, 12B) of another DMA module upstream in the chain. The DMA modules interact with the respective IP blocks (A, B, C) by writing data from the input buffer (11A, 11B, 11C) of the IDMA module into the respective IP block (A, B, C) and reading data from the respective IP block (A, B, C) into the output buffer (12A, 12B, 12C) of the DMA module. The input (11A, 11B, 11C) and output (12A, 12B, 12C) buffers in the various DMA module are operated in such a way that; - writing of data from the input buffer (11A, 11B, 11C) of the DMA module into the respective IP block (A, B, C) is started when the input buffer (11A, 11B, 11C) is at least partly filled with data; - when said reading of data from the respective IP block (A, B, C) into the output buffer of the DMA module is completed, the data in the output buffer are transferred to the input buffer (11B, 11C) of the DMA module downstream in the chain or, in the case of last DMA module in the chain are provided as output data.

Users of mobile terminals in a communication network are provided controlled access to files in a file system through the steps of: configuring the files as a file body containing a file content and a file header containing content profile information, Providing a security identity module and a secure agent, storing in the security identity module user profile information identifying a set of content profiles allowed for access to the file system, extracting, via the secure agent, the content profile information from the headers of the files, retrieving, via the secure agent, the user profile information stored in the security identity module, checking the user profile information and the content profile information, and providing the user with access to those files in the file system for which the user profile information and the content profile information are found to match.
