ABSTRACT:
The invention relates to electronic chip cards and, more particularly, in such cards, organisation systems which make it possible to configure them with a view to using them as servers of the type used in the network known as the Internet.
Electronic chip cards are being more and more widely used for performing various functions in relation to equipment such as computers for personal use, mobile telephone handsets, banking terminals, etc. To this end, they are configured as electronic circuits and software for communicating with the equipment with which they are connected in accordance with communication protocols which are relatively simple and are defined by ISO 7816-3/4.
These communication protocols do not make it possible to access the, electronic chip card in a network of the Internet type using the addressing method utilised in such a network for access locally or at a distance to all types of application (texts, images, sound, voice, files etc)
The current organisation of electronic chip cards and the communication protocols which they use do not therefore make it possible to use them as servers of the type used in the Internet.
One aim of the invention is therefore to produce an electronic chip card which can be used as a server in a network of the Internet type through a terminal adapted for accessing this network.
To achieve this aim, the invention proposes systems for organising electronic chip cards which enable any user of the network to which it is connected to communicate with it in accordance with a common and universal addressing language.
In order to simplify the reading of the description and claims, the acronyms defined below will be used as substantive:
URL is the acronym of the English expression “Uniform Resource Locator” and defines a means for locating and naming a resource (file, text, sounds, images, application, program or data table and generally referred to ask an “object” ) available on a server, in the field of the Internet. There exist several URL access schemes which each correspond to an access protocol, for example “http://” and “ftp://” which allow distant access via a network, or “file://” which allows access to a local file system.
WWW is the acronym of the English expression “World Wide Web” and defines the world-wide network of information and services of the Internet.
WAP is the acronym of the English expression “Wireless Application Protocols” and defines a set of protocols of the wireless telephony network enabling mobile terminals to connect to and access the information and servers of the Internet.
HTML is the acronym of the English expression “HyperText Markup Language” and defines a language for defining the structure and display of the document or file as well as the elements for browsing within the WWW network.
HTTP is the acronym of the English expression “HyperText Transfer Protocol” and defines the communication protocol of the WWW network making it possible notably to recover the resources available on the WWW network.
WSP is the acronym of the English expression “Wireless Session Protocol” and defines a WAP protocol layer equivalent to the HTTP protocol.
TLS is the acronym of the English expression “Transport Layer Security” and defines the protocol relating to the determination of the security parameters and algorithms in order to establish a protected session between a client terminal and a server.
WTLS is the acronym of the English expression “Wireless Transport Layer Security” and defines the TLS protocol transposed to wireless telephony in all the WAP protocols.
TCP/IP is the acronym of the English expression “Transmission Control Protocol/Internet Protocol” and defines a protocol layer of the communication level used in the Internet which manages the addressing and routing of the data packets in the network.
WTP is the acronym of the English expression “Wireless Transport Protocol” and defines a WAP protocol layer equivalent to the TCP/IP protocol on the Internet.
WML is the acronym of the English expression “Wireless Markup Language” and defines an HTML language simplified for the WAP protocol.
WAE is the acronym of the English expression “Wireless Application Environment” and defines the application environment of the client terminal, that is to say the client browser, in the WAP protocol for access to the services of the Internet.
WTA is the acronym of the English expression “Wireless Telephony Application” and defines an application environment of the client terminal in the WAP protocol for the telephony services.
CGI is the acronym of the English expression “Common Gateway Interface” and defines an interface for access to the applications of the WWW. This interface makes it possible to activate applications on the WWW servers using a URL request sent from a client browser. This interface supports the passage of input parameters to the applications.
APDU is the acronym of the English expression “Application Protocol Data Unit” and defines an elementary exchange format for commands between an application on a terminal and an application on a chip card. It is a case for example of the ISO 7816-4 standard.
SQL is the acronym of the English expression “Structured Query Language” and defines the language used in the interrogation of relational databases.
SCQL is the acronym of the English expression “Structured Card Query Language” and defines the query language for a chip card of the database type, in accordance with ISO 7816-7. SCQL is the equivalent in chip cards of the SQL language used in the interrogation of relational databases.
BNF is the acronym of the English expression “Backus-Naur Form” and defines a symbolic pseudocode for defining syntactical rules of a language and a grammar.
GSM is the acronym of the English expression “Global System for Mobiles” and designates a mobile telephony system.
SUMMARY OF THE INVENTION
The invention therefore relates to a system for organising an electronic chip card with a view to its use as a server by means of a terminal to which it is connected in a digital data transmission network such as the Internet, the electronic chip card comprising a microprocessor, and memories containing programs and data for implementing the operating system of the electronic chip card and for managing the inputs/outputs of the electronic chip card, characterised in that it also comprises:
means for translating the commands coming from the terminal into elementary commands of the electronic chip card,
means for performing the operations defined by the elementary commands, and
means for formatting the response from the electronic chip card to the terminal.
The means for translating the URL commands comprise a look-up table recorded in one of the memories.
In a variant, the electronic chip cards also comprise means for implementing session (WSP) and transmission (WTP) protocols.
