Abstract

Chip cards, or smart cards, are used as servers in association with a digital data transmission network terminal. The chip card comprises a microprocessor and memories which contain programs and data for interpreting the URL'"'"'s coming from a network terminal, translating them into elementary commands of the chip card and formatting a response to the terminal. Some of these functions can be performed by the terminal with which the chip card is associated. The invention is applicable to networks transmitting digital data and programs of the Internet or mobile telephone system type.

Claims

1. An electronic chip card that functions as a server by means of a terminal in a digital data transmission network, said electronic chip card comprising:

a microprocessor,

memories containg programs and data for implementing an operating system of the electronic chip card for managing inputs/outputs of the electronic chip card,

means for translating commands from the terminal into elementary commands of the electronic chip card,

means for performing operations defined by the elementary commands, and

means for formatting a response from the electronic chip card to the terminal.

2. An electronic chip card according to claim 1, wherein said means for translating the commands comprise a look-up table for URLs which is specific to each type of chip card.

3. An electronic chip card according to claim 2, wherein said means for translating the commands further comprise a URL interpreter program recorded in one of said memories.

4. The electronic chip card of claim 1, wherein said chip card communicates with the terminal by means of a protocol that conforms to an international standard for integrated circuit cards.

5. The electronic card of claim 1, wherein said chip card communicates with the terminal by means of commands that conform to the APDU format.

6. The electronic chip card of claim 1, wherein the terminal comprises a mobile telephone handset.

7. An electronic chip card that functions as a server by means of a terminal in a digital data transmission network, said electronic chip card comprising:

a microprocessor,

memories containing programs and data for implementing an operating system of the electronic chip card for managing inputs/outputs of the electronic chip card,

means for translating commands from the terminal into elementary commands of the electronic chip card,

means for performing operations defined by the elementary commands,

means for formatting a response from the electronic chip card to the terminal, and

means for implementing session and transmission protocols.

8. An electronic chip card according to claim 7, wherein said means for implementing the session and transmission protocols comprise programs recorded in one of said memories.

9. The electronic chip card of claim 7, wherein said session protocol comprises WSP.

10. The electronic chip card of claim 9, wherein said transmission protocol comprises WTP.

11. The electronic chip card of claim 7, wherein said transmission protocol comprises WTP.
