Abstract: A data processor, such as, for example, a smart card, comprises a controller for managing a file wherein a plurality of records can be stored in a sequential fashion. The controller checks whether a record has correctly been written into the file. The controller prevents user-related software from reading the record that is subsequent to the last record that has correctly been written.

Abstract: A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network. The data processing device and the remote system are adapted to store a plurality of parameters identifying a user account belonging to a subscriber. The data processing device comprises a one-time parameter comprising the active account attached to the device designed for a one-time use, and a permanent parameter identifying an account attached to the data processing device, the permanent parameter being deactivated. The one-time and permanent parameter are stored in the at least one remote system, and the microcontroller is programmed to: use the one-time parameter to logon to the network when the data processing device is switched on; and exchanges the one-time parameter with the permanent parameter, upon successful logon to the network, the permanent parameter becoming the permanent active account. The first device and the at least one remote system store a parameter identifying a current active account attached to a second data processing device to replace, and upon successful logon to the network, a program automatically stored in the first device sends an activation request for exchanging the plurality of parameters from the old for the new one in the at least one remote system, with the current active account being deactivated.

Abstract: A data communication device comprises an input circuit (DRTC) that converts external data (XDT) into internal data (IDT) on the basis of a sampling signal (SP). A synchronization circuit (SYNC) provides the sampling signal (SP) on the basis of an oscillator signal (OS) and a synchronization value (SV). The synchronization value (SV) is representative of a number of cycles of the oscillator signal (OS) contained within a time interval for a unit of external data. The synchronization value (SV) is an initial value (IV) during an initial synchronization phase and a measured value (MV) during a measurement-based synchronization phase. A control circuit (IFC) carries out a calibration step in which the initial value (IV) is a preprogrammed reset value (RV) and in which the measured value (MV) is stored as a calibration value (CV). The control circuit (IFC) applies the calibration value (CV) as the initial value (IV) in subsequent initial synchronization phases.

Abstract: PCT No. PCT/FR95/01061 Sec. 371 Date Apr. 23, 1997 Sec. 102(e) Date Apr. 23, 1997 PCT Filed Aug. 8, 1995 PCT Pub. No. WO96/05548 PCT Pub. Date Feb. 22, 1996The invention relates to protected keypad apparatus, in particular for machines actuated by insertion of an electronic smart card. The keypad proper (10) comprises n sensitive zones (Zi), each sensitive zone being associated with a respective sensor and with an individual processing circuit (14i) that includes in particular an encryption function. The sensor and the circuit form a monolithic unit. The apparatus further includes a driver unit (18) connected to each circuit (14i) via a bus (16). The circuits periodically and cyclically transmit encrypted signals indicating activation or non-activation of the sensitive zones.

Abstract: The method involves storing an asynchronous message sent by a card agent (CA) to a standard agent (AS) or vice-versa in a storage unit of a network (1) by one of the intermediate agents (CEPA, CAPA). The intermediate agent manages the communications of the card agent with the network. A card engine proxy agent (CEPA) transmits the message from AS to CA and stores the message in the network. An Independent claim is also included for a communication system.
