- CAFE European project Esprit number 7023
- FIG. 1 schematically illustrates the structure of the device according to the invention, as well as the elements to which it can be connected, or with which it can communicate.
- the device 11 thus comprises a microprocessor 111, capable of doing so function, from the information (program, configuration ...) contained in a reprogrammable memory 112. It still includes means 113 to ensure Securing the issuance of a check (coding of cryptographic signatures based on on public key algorithms, PIN verification, security module in the form of "plug-in” ...) taking into account information (number of checks and amount) contained in a transaction resource memory 114, and means 115 contactless communication, for example by infrared, with a terminal of These means 115 may, for example, implement the IRDA standard. ("InfraRed Data Association"), at 38400 bauds.
- the device 11 has means 116 for dialogue with one or several micro-circuit cards 13, for example according to the ISO 7816-3 standard.
- the means of dialogue 11 6 operate at a predetermined nominal transmission frequency (for example 7 MHz), which can be reduced to a fallback transmission frequency corresponding to the half (ie the normalized 3.5 MHz frequency) if there are problems in the exchange of data is detected.
- a predetermined nominal transmission frequency for example 7 MHz
- the cards 13 include complete means for performing a transaction (independently of the device 11) such as similar security means 131 means 113, a resource memory 132 and a microprocessor 133.
- the device 11 comprises a multiplexer 117, or any other means for make a selection (this can for example also be carried out directly by the microprocessor 111).
- the multiplexer 117 makes it possible to choose between the means for perform a transaction of the device or those of a card. In both cases, the communication is provided by the infrared communication means 115, under the control of the microprocessor 111.
- the security of the transaction is fully supported by the element (card 13 or device 11) which ensures the transaction. So when it comes to the card, the device works so transparent, only to allow contactless communication.
- the device 11 comprises means 118 for detecting the presence of a card in the means of dialogue 116, and to check its validity. In one embodiment of the invention, these means act directly on the multiplexer 117 for select the card as soon as a valid card is present.
- a transaction may include the issue of a check or a check reloading of resource memories. This last operation is carried out preferentially systematically in the memory 114 of the device. It is then possible to transfer this memory 114 to the memory 132 of the card. Other types of transfer are of course possible, depending on the applications.
- the invention furthermore provides an advantageous technique for the maintenance or configuration (that is, operations that can only be performed by authorized persons) of the device 11.
- the authorized person has a keying device 14, which has the same format, as well as the same electrical contacts, as a card 12, so that it can be inserted into the dialogue means 116.
- This key 14 comprises means 141 which allows the device 11 to detect that it is a access request for maintenance and not a conventional card.
- This means 141 is by example a mechanical and / or electrical keying.
- the polarizer 14 moreover advantageously comprises a feed 142 in a voltage (for example 12 V) for erasing the contents of the memory of programming 112, in order to reprogram it.
- This erase voltage 142 is greater than the operating voltage of the device (for example 5 V).
- the microprocessor 111 can communicate with a maintenance terminal 15. Preferably, this communication is carried out according to the same protocol (infra-red) than a transaction communication.
- the polarizer 14 may comprise directly intelligence (microprocessor and memory), or be a micro-circuit board specific, allowing maintenance or configuration.
- FIG. 2 is a more detailed block diagram of an embodiment of the device 11.
- a low-power microprocessor 21 for example of the MCU 8051 type (registered trademark), manages the operation of the device, depending on the information stored in the program memory 22 and the data memory 23 (which are accessible during the maintenance and configuration operations indicated above).
- the microprocessor 21 manages on the one hand the relations with the means of communication 25, comprising the infrared interface 251, and on the other hand the interface man / machine 26, which includes a keyboard 261 (with 14 keys for example) and a screen 262 (for example 2 lines of 16 characters, liquid crystal).
- This man / machine interface 26 makes it possible to provide numerous services user-friendly, such as consultation (visualization of the balance of the device and card), configuration and customization of the device, ...
- a non-volatile memory 24 stores the data corresponding to the resources transaction (number of checks, amount available, maximum amount allowed, blank checks, ).
- Securing a transaction when it is performed by the device, is provided preferentially by a cryptographic coprocessor 271 connected to the microprocessor 21 and by a security module 272.
- This security module has essentially to protect the interests of the bank. It is therefore a module monitoring (still called “observe"), configured in a particular mode and inaccessible to users, which maintains a secure image of the content of the resource memory (also called “purse”). Any operation carried out on the Resource memory systematically affects this monitoring module. Note that the card also includes such a security system.
- the microprocessor 21 When the transaction is performed by a card, the microprocessor 21 is connected to the interface 28 with the card. In order to use only one access bus to microprocessor 2 1, a multiplexer 29 associated with this bus is the interface 28, if a card is present, the security module 272.
- Figure 3 shows an example of operation of the system described above.
- the possible operations are of course different according to the fashion.
- Any operation in connected mode begins, of course, by the institution. a connection between a terminal and the portable device.
- the communication to be established is bi-directional, but the procedure 31 is preferentially unsymmetrical. It's about of a master-slave procedure, the terminal playing the role of the master.
- the exchange of messages can begin, and the two-way communication remain active until the slave device is switched off or communication area, or until the exchange of data is normally by the terminal-master.
- the device when turned on, the device performs systematically a connection test, to determine whether or not it is in a communication area. He then repeats this test regularly.
- connection Once the connection is established, at least three types of operations are possible (32): payment, reloading and maintenance.
- the first two, called transactions, are carried out by the carrier of the device.
- the third is reserved for authorized persons.
- the recharging 38 is performed between the terminal and the resource memory of the device, following a procedure similar to that described above for payment. It is possible to recharge in blank checks and in financial amount (s), possibly in several currencies.
- the device verifies (311) the presence of the polarizer. If the keying is present, a dialogue can be established with a configuration terminal, via infrared communication means.
- the protocol of communication allows direct access to most of the components forming the device, for configuration or miantenance operations.
- the query 310 makes it possible, for example, to consult the balance of the account (or accounts, when multiple accounts in multiple currencies are managed) on the card and / or on the device, as well as view the list of the last transactions made and memorized, or exchange rates:
- the transfer of resources can be done (314) of the card to the device 315 (for example when one wants to get rid of the remaining of a card), or from the device to card 316 (for example when one comes from recharge the device). It is also possible to make transfers of credited checks of a chosen amount, from a card to a device and vice versa (in particular in order to effect a transaction between two persons, one being of the device and the other of the card).
