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:
The invention concerns a method of manufacturing a slice of semiconductor. The slice of semiconductor comprises an active face and an inactive face. A passivation layer (pass) is deposited on the active face. The method comprises an organic-layer-depositing step, in which an organic layer (ORGA1) is deposited on the inactive face of slice of semiconductor.
摘要:
A smart card which includes a non-volatile read/write memory and a processor connected to the memory, and further configured to cause the processor to perform a method for enhancing data security and managing the contents of memory during periods when the computational power of the processor is underutilized. The method includes steps for determining if a command or character has been received, processing and/or responding to the command or character once received, implementing a security measure and/or managing memory, and performing a tamper protocol in response to detecting a security breach, all of which is performed while waiting to receive the next command or character.

摘要:
The invention concerns a method for transferring computer files between a remote server (5) and a network of service appliances (10) such as public telephones, said files being used by said service appliances (10) for operating, the server (5) communicating with the service appliances (10) via a telecommunication network (2). The invention is characterised in that said files are first stored in the server (5), then transferred into a separate FTP server (4) from which they are downloaded by said service appliances (10), said service appliances having previously received instruction from said server (5) to proceed with the downloading of said files in said FTP server (4).
摘要:
A method and device is disclosed for generating a local clock signal CLK1X (172) from Universal Synchronous Bus downstream-received differential signals DM and DP carrying the downstream received bit-serial signal. The method and device does not require the use of a crystal or resonator. Counters (312, 310, 305, 301) are used to determine a number of periods of a free-running high frequency clock signal (164) contained within in a known number of bit periods of the downstream received bit-serial signal (146). The counter values are divided by the known number of bit periods of the received bit-serial signal (146) to determine a bit period of the received bit-serial signal (146). The local clock signal (172) may be phase-locked with the received bit serial signal (146). The local clock period is updated on an ongoing manner by downstream known received traffic.
