摘要： The invention relates to installations for testing components, particularly electronic chips having a permanently-increasing performance, especially in terms of current supported over long periods. In order to perform said tests correctly, the invention provides for a device that can deliver currents of up to and of the order of 200A in a few microseconds. For this purpose, the device comprises a time-dependent power chopper (PWM) linked to a high-frequency linear amplifier (HFLA).

摘要： The invention relates to a method of updating an authentication algorithm in at least one data processing device (CARD, SERV) which can store a subscriber identity (IMSI1) which is associated with an authentication algorithm (Algo1) in a memory element of said device (CARD, SERV). The inventive method comprises the following steps, namely: a step whereby a second inactive (Algo2) authentication algorithm is pre-stored in a memory element of the device and a step for switching from the first algorithm (Algo1) to the second algorithm (Algo2) which can inhibit the first algorithm (Algo1) and activate the second (Algo2).

摘要： The invention concerns a method for data transmission between an electronic smart card (4), a terminal such as a computer (1) and a user, said smart card comprising a central processing unit (CPU) connected via a data bus and addresses to storage units (ROM, RAM, EEPROM) and comprising an assembly of eight bond pads electrically connected to corresponding contact pads borne by the smart card. The invention is characterized in that the central unit exchanges data with said terminal (1) in accordance with universal serial bus (USB) standard through first and second contact pads (D+, D-) and in that the central unit communicates data to the user through a third contact pad (I/O) connected to specific visual or audio communication means (6).

摘要： An identity module (SIM 101) is activated in the following manner. A customization center (106) stores an initial identity code (IMSI) in the identity module (101) and communicates the initial identity code to a network management system (103, 104). A distributor (107, 108) assigns a communication address (MSISDN) to the identity module and (101) communicates the communication address together with the initial identity code to the network management system (103, 104). The identity module (101) contacts the network management system (103, 104) via a communication device (mobile phone), whereby the network management system (103, 104) receives the initial identity code together with the communication address. The network management system (103, 104) recognizes the initial identity code together with the communication address and, in response, assigns an effective identity code to the identity module (101). Subsequently, the network management system (103, 104) sends a message to the communication device (mobile phone). This message (a special SMS) comprises the effective identity code. The identity module (101) receives the message via the communication device, extracts the effective identity code from the message and stores the effective identity code for future use.

摘要： The invention concerns a method for making secure a commercial transaction between a merchant (7) and a user wherein the user must communicate personal data such as a banking card number. The invention is characterised in that it consists in: obtaining with a first microprocessor banking card (1) a second banking card (11) from an appropriate issuing institution (101), and in using the data of said second card (11) such as its number (12) during said transaction, said second card (11) being valid only for a limited number of transactions.
