- communications on networks are carried out in accordance with protocols meeting standards comprising several software layers. superimposed.
- communications are carried out according to protocols specific to this type of communications, which will be detailed below, but which also include several software layers.
- the communication protocol is chosen according to the application more particularly targeted: interrogation of "WEB” pages, file transfers, electronic mail (e-mel, or “e-mail” according to Anglo-Saxon terminology), forums or “news”, etc.
- FIG. 1B The logical architecture of the system comprising a terminal, a smart card reader and the smart card, is shown diagrammatically in FIG. 1B. It is described by the ISO 7816 standard, which itself comprises several sub-assemblies: - ISO 7816-1 and 7816-2, with regard to the dimensions and marking of the cards;

- the applications are referenced A ⁇ , ... , A ⁇ , ..., A n ; n being the maximum number of applications present on the smart card 2.
- This game typically presents writing orders and reading orders.
- the format of the orders is known by the Anglo-Saxon abbreviation of "APDU” (for "Application Protocol Data Unit”). It is defined by the aforementioned ISO 7816-4 standard.
- a command “APDU” is noted “APD ⁇ r .co-7--7iand” and a response “APDU” is noted “APDU.response”.
- a ⁇ application is, for example, in the form of a piece of software, known as an "applet”, in the "JAVA” language (registered trademark), which will be called “cardlet” below.
- the selection of a particular "cardlet” A ⁇ is obtained using an "APDU” of the selection type ("SELECT"). Once this choice has been made, the "APDUs" which follow it are routed to this "cardlet”.

- the upper application layer ("http”, “ftp”, "e-mail”, etc.) has not been shown.
- the interface between the lower layers, Ci and C2, and the upper layers, C 3 and C 4 is constituted by a software layer generally called "low layer driver".
- the upper layers, C 3 and C 4 rely on this interface and are implemented by means of libraries of specific functions or network libraries 14, with which they correspond.
- libraries of specific functions or network libraries 14, with which they correspond.
- TCP / IP is implemented by means of libraries known as “sockets”.
- This organization allows a browser 10 (FIG. 1) to ask requests to a server 4 (FIG. 1), for consulting "WEB” pages (“HTTP” protocol), for transferring files (“FTP” protocol) or sending electronic mail (“e-mail” protocol), in a completely classic way.
- HTTP HyperText Transfer Protocol
- FTP File Transfer Protocol
- e-mail electronic mail
- the terminal 1 also includes a card reader 3, integrated or not.
- the card reader also includes two layers bass, CCi (physical layer) and CC 2 (data link layer), playing a similar role to layers Ci and C 2 .
- the software interfaces with the layers CCi and CC2 are described, for example, by the specification "PC / SC"("part 6, service provider").
- the layers themselves, CCi and CC2 are in particular described by ISO standards 7816-1 to 7816-4, as has been recalled.
- An additional software layer 16 forms the interface between the application layers (not shown) and the lower layers, CCi and CC2.
- the main function assigned to this layer is a multiplexing / demultiplexing function.
- the communications with the smart card 2a are carried out according to a paradigm similar to that used for the manipulation of files in an operating system of the type "UNIX” (registered trademark): OPEN ("OPEN”), READ (“READ "), WRITE, CLOSE, etc.
- OPEN OPEN
- READ READ
- WRITE WRITE
- CLOSE CLOSE
- CCai physical layer
- CCa 2 data link layer
- a first characteristic provision is made, on either side, that is to say in the terminal 1 and in the smart card 2a, two layers of specific protocols: 13 and 23a, respectively, corresponding to means network interface.
- the specific layer 13 interfaces with the "low layer drivers” 15, with the libraries 14 of the network layers, C 3 and C4, and with the protocol layers of the card reader 3, that is to say the lower layers, CCi and CC 2 , via the multiplexing layer 16.
- the specific layer 13 allows the transfer network packets from and to the smart card 2a.
- it adapts existing applications such as the Internet browser 10 (FIG. 2), electronic mail, etc., for uses using the smart card 2a.
- a module, 130 or 230a for transferring information blocks between the layers 13 and 23a, via the conventional layers CCi, CC 2 , CCai and CCa 2 ; - one or more pieces of software, called "intelligent agents", 132 or 232a, which perform, for example, protocol conversion functions;
- a specific configuration management module 131 and 231a, respectively; module which can be likened to a particular intelligent agent.
- level two data link layers
- CC2 and CCa 2 ensure the exchange between the smart card 2a and the terminal 1.
- These layers are responsible for the detection and possible correction of transmission errors .
- Different protocols can be used, and as non-exhaustive examples the following: - the ETSI GSM 11.11 recommendation;
- HDLC High-Level Data Link Control procedure
- the ISO 7816-3 protocol will preferably be used, in block mode.
- each protocol layer is associated with a certain number of primitives which allow the exchange of data between layers of the same level and from one layer to another.
- the primitives associated with the layer of level two are of the type "data request” ("Data .request”) and “sending of data” by the card (“Data .response”), as well as “ data confirmation "(” jData.co.n.fir-71 "), etc.
- the layers 13 and 23a are responsible for the dialogue between the smart card 2a and the host, that is to say the terminal 1. These layers allow the exchange of information between a user (not shown) of terminal 1 and the smart card 2a, for example via drop-down menus in the form of hypertext in "HTML" format, as will be shown with regard to FIG. 3. They also allow the establishment of a configuration suitable for the transmission and / or reception of data packets.
- the layers include three separate entities.
- the first layer, 130 or 230a is essentially constituted by a software multiplexer. It allows the exchange of information between the smart card 2a and the host terminal 1, in the form of protocol data units. It plays a role similar to that of a data packet switch. These units are issued or received via level 2 layer (data link layer).
- This particular communication protocol makes it possible to put at least one pair of "intelligent agents" into communication.
- the first agent of each pair, 132 is located in layer 13, on the terminal side 1, the second, 232a, is located in layer 23i, on the smart card side 2a.
- a link between two "intelligent agents" is associated with a session.
- a session is a two-way data exchange between these two agents.
- An intelligent agent can perform all or part of the functions of the layers of levels three and four, depending on the configuration implemented by the terminal 1.
- a particular intelligent agent is advantageously identified by an integer, for example on 16 bits (number between 0 and 6535). This identifier is used, for example, in a protocol data unit constituting a destination reference and a source reference.
- agents of the "server” type which are identified by a fixed reference
- agents of the "client” type which are identified by a variable reference, delivered by the management module. configuration, 130 or 230a.
- the process for opening a session is usually as follows: an intelligent agent of the "client” type opens the session to an intelligent agent of the "server” type.
- Layers 130 and 230a manage tables (not shown) which contain the list of intelligent agents present, on the host terminal side 1 and smart card 2a.
- Intelligent agents are associated with particular properties or attributes. To fix ideas, and by way of nonlimiting example, the following six properties are associated with intelligent agents:
- agent who initiates a session
- agent who receives a session request.
- Intelligent agents are used to exchange data (hypertext for example), but also to trigger network transactions.
- the configuration management modules, 131 and 231a can be assimilated, as indicated, to particular intelligent agents.
- the module 131 on the host terminal side 1, manages in particular information relating to the configuration of this terminal (operating modes), list of the other agents present, etc.
- the module 231a on the smart card side 2a, has similar functions. These two agents can be put in communication with each other to establish a session.
- the smart card 2a offers the host system, that is to say the terminal 1, a model of virtual terminal. To do this, the smart card 2a behaves like a "WEB" server.
- the smart card 2i is "addressed” by the browser 10. It then transmits to it a "WEB” type page in "HTML" language, an “applet” or any other piece of software.
- the "WEB” page can be in the form of a home page giving a choice of possible applications and / or hyperlinks to external servers.
- the smart card 2a is advantageously “addressed” by using a "URL” address (for "Universal Resource Location") defining a loopback on the terminal 1 itself, and not a pointing on an external server .
- the structure of this "URL” is usually as follows: http://127.0.0.1:8080 (1), in which 127.0.0.1 is the loopback "IP" address and 8080 is the port number.
- FIG. 3 schematically illustrates this process.
- the smart card 2a in response to the request from the browser 10, the smart card 2a has a page P in "HTML" language, page displayed for example on the display member 5 of the terminal 1.
- the page P which we will describe as reception, can display, in the usual way, different graphic or text elements, but includes at least a certain number of hyperlinks to external servers, Hl ⁇ , Hl 2 ⁇ ••• / Hl ⁇ , at i and n being arbitrary numbers, n represents the maximum number of possible choices. It naturally depends on the smart card 2a inserted in the reader 3, and on the maximum number n of application A ⁇ (FIG. 1B) present on this card. The choices presented may depend on the rights which are granted to the owner of the smart card 2a: subscription subscribed to services, level of authorization, etc.
- the process described uses all or part of the standard communication layers (not shown), as well as the specific layers, 13 and 23a.
- Each hyperlink points to an external "URL” resource.
- the structure of the "URL” can be as follows: http: //127.0.0.1.8081/www.NOM.com/index.html (2), in which 127.0.0.1 is the "IP” address and 8081 is the port number, "NOM.com” the name of a website for a company or other entity, in accordance with the rules of naming usually used, and "index.html” the home page of this site.
- suffix ".corn” a priori used for commercial organizations, there are other suffixes, such as “.fr", ".gov”, etc. , which are associated with the location of the website or the nature of the organization.
- FIG. 4 illustrates in a simplified manner the logical architecture of a system of which the smart card 2a comprises intelligent agents, of which only two have been shown: an intelligent agent of the type not precisely defined 232a ⁇ and an intelligent agent 232a ⁇ , type called "WEB".
- the logical stack comprises, the lower protocol layers, referenced 200a, meeting ISO standards 7816-3 (FIG. 2: CCai and CCa 2 ), the "APDU" command manager 201a, and the packet multiplexer 230a, the latter being interface to intelligent agents, in particular the intelligent agent "WEB" 232a ⁇ -
- the first stack includes the organs 11 (FIG. 2: Ci and C 2 ) for accessing the network (OSI standards 1 and 2) and the "TCP / IP" protocol layers (FIG. 2: C 3 and C4), referenced 100 These latter layers are interfaced with the "WEB" browser 10.
- the other stack includes the lower protocol layers, referenced 101, meeting the ISO 7816-3 standards (FIG. 2: Ci and C 2) the order manager 101 "APDU" and the packet multiplexer 102, the latter being interface with intelligent agents, of which only one 132 is shown.
- the latter which will be assumed to be "network type" can also communicate, on the one hand with the browser 10, via the "TCP / IP” layers 100, on the other hand with the Internet network RI, via these same layers “TCP / IP” 100 and member 11, for access to the RI network.
- the "APDU" order manager 201a also interfaces with one or more level layers applications, which we will simply call applications. These applications are, as has been indicated, applications of the conventional type, which have been called “cardlets”.
- the "WEB server" function provided by the smart card 2a, can be performed by combining the intelligent agent "WEB" 232a ⁇ in the smart card and the network agent 132 in the terminal 1 .
- the smart card 2a therefore clearly presents the "WEB” server functionality.
- any conventional application, Ai to A n of the aforementioned "CGA” type, can be activated through this "WEB” server, or by the "WEB” browser.
- the applications, Ai to An do not need to be rewritten and are implemented as they are.
- these applications remain accessible to a terminal of the conventional type, that is to say according to the known art.
- WEB offered by the smart card, includes application interface means, corresponding to a mechanism similar to the so-called “CGI” function (for "Common Gateway
- CGI is a specification for the implementation, from a “WEB” server, of applications written for the "UNIX” (registered trademark), "DOS”, or "WINDOWS” (registered trademark) operating systems.
- UNIX registered trademark
- DOS registered trademark
- WINDOWS registered trademark
- an "HTTP" request for a "URL” address of the type:
- host refers to a host system (generally remote)
- WEB writeback server
- command script of the "CGI” type named "xxx” and present in the " cgi-bin "from this host system.
- name of the directory can be a priori arbitrary, by convention, it is the name given to the directory storing scripts of type "CGI”.
- a script is a series of instructions from the operating system of the host system, the final result of which is transmitted to the "WEB" browser issuing the above request.
- Different languages can be used to write this script, for example the language "PERL” (registered trademark).
- the request is usually displayed on a computer screen in the form of a form included in a "HTLM” page.
- the "HTLM” language allows you to translate a form into a "URL” address.
- the form includes one or more fields, mandatory or not, which are filled in by a user using the usual input methods: keyboard for text, mouse for checkboxes or so-called “radio” buttons, etc.
- the content of the form (as well as possibly so-called “hidden” information and instructions) is sent to the "WEB” server.
- the "HTLM” code on the page describes the physical structure of the form (frame, graphics, color, and any other attribute), as well as the structure of the data fields to be entered (name, length, type of data, etc.).
- Transmission can take place in two main types of formats.
- a first format uses the so-called "POST” method and a second uses the so-called "GET” method.
- Format type information is present in the code of the form page.
- the example form has two numeric fields, Ch ⁇ and Ch2, entitled “Certificate” and Debit “, as well as two buttons “radio”, i> ⁇ and b2, entitled “Submit” and “Reset”, respectively. It also includes, on the right of the figure, the usual function called "elevator”. This form is displayed on the display screen (figure 1: 5) of terminal 1.
- a third step the user completes the two numeric fields, C ⁇ i and Ch 2 .
- both fields must be completed.
- Ji the user transmits the content of the form.
- £ 2 it erases all the data displayed, either to correct them or to enter a new series.
- the data is sent and received by the network agent 132. It is recalled that the "WEB" browser is not necessarily located in the local terminal 1. It can be either in this one ci or located in any system connected to the network
- the data then passes through the packet multiplexer 130 (which constitutes one of the components of the specific layer 13, terminal side 1), the "APDU" order manager 102, the protocol layers 101, to be transmitted to the card at bullet 2a. They then pass through the protocol layers 200a, the "APDU” order manager 201a, the packet multiplexer 230a to be received by the agent.
- the data sent to the "WEB” agent 232a ⁇ is transported conventional per se, in the form of "APDU” orders intended for the particular application "Packet multiplexer".
- the “APDU” order manager 201a selects this application in a manner very similar to the other “CGA” type applications present in the smart card 2a, referenced Ai to A n .
- the packet multiplexer 230a is seen by the "APDU” order manager 201a as an ordinary "CGA” application.
- the "HTTP" request is then analyzed by the "WEB” agent 232a ⁇ which detects a reference to a particular directory, which will be called hereinafter by convention "cgi-smart", on the one hand, and to an application particular, for example "pme” in the case of the example described.
- the full path is therefore, in this case "cgi-smart / pme”.
- the above entity designates a particular script associated with an equally particular application ("PME" in this case).
- the script is then interpreted by an intelligent agent called “Script translator agent”, which will be called “ATS” below.
- This translation can be carried out in different ways: a / by the "WEB” agent 232a ⁇ itself, which in this case is provided with a double capacity; b / by a single script agent capable of translating all the scripts present in the smart card 2a; c / by a dedicated scripting agent which will be called “ATSD” below (one per script); or d / by an agent "APDU” 2010a of the order manager "APDU” 201a, which is equipped, in this case, with a double capacity.
- the "APDU” agent 2010a is a component of the "APDU” order management layer 201a.
- the latter is a layer capable of centralizing all the "APDU” orders sent and / or received by the system, from select applications, from Ai to A, but also to offer an intelligent agent type interface. It is therefore capable, according to one of the characteristics of the method, of communicating with all the intelligent agents of the system (via sessions), whether these agents are located in the terminal 1 or the smart card 2a.
- FIG. 5A illustrates an example of architecture for which the translating agents are of the "ATSD" type. They are referenced ATS1 to ATSn and associated with the applications Ai to A - The selected application being assumed to be the application A ⁇ , the session is established between the "WEB" agent 232a ⁇ and the agent ATS ⁇ .
- a script translator agent generates a sequence of "APDU” orders.
- a session is opened between the translating agent, for example the ATS ⁇ agent, and the "APDU” agent 2010a.
- the orders are then issued to the "APDU” agent 2010a.
- the "APDU” order manager 201a selects the "CGA” A ⁇ application (for example the "PME” application) and transmits to it the "APDU” orders, translated and therefore conventional orders, which it is able to understand. This application is therefore correctly activated, without having to modify or rewrite it.
- the responses of the "CGA” A ⁇ application are transmitted to the "APDU” order manager 201a, to the "APDU” agent 2010a, then again to the ATS agent ⁇ (and more generally to the script translator agent).
- the script translator for example the ATS ⁇ agent in the example in FIG. 5A, creates a page in "HTML" language and transmits it via the different layers borrowed by the initial request, but in reverse, this to be presented on the display screen 5 ( Figure 1).
- the smart card 2a must be able to continue to be used in conjunction with a conventional terminal.
- the smart card no longer plays the role of "WEB” server and the "intelligent agents” functionalities are not used. It is the same for the specific layer 23a ( Figure 2).
- These various components remain “transparent” vis-à-vis the exchanges between terminal and smart card. These exchanges are carried out in a purely conventional manner, by exchange of "ADPU" orders between an application located in the terminal and an application located in the smart card, as has been explained with reference to FIGS. 1A and 1B.
- FIG. 7 schematically summarizes the main stages of the process which has just been described: a / transmission via the Internet network RI (or from the local terminal: in both cases using a conventional browser 10) of a request
- HTTP referenced RQ
- b response from the “WEB” server of the smart card 2a, in the form of a form, referenced FO; c / transmission of the completed form, in the form of a new RQ request; and d / response in the form of a page "HTLM”, referenced PR.
- the answer could also consist in the transmission of a file, or a piece of software or "Applet”.
- the system can accommodate unconventional applications. By this is meant applications which do not need to exchange "APDU" orders.
- This type of application which does not meet the aforementioned ISO standards, is not accessible by conventional terminals, but is, without requiring any additional modification of their architecture, by terminals in accordance with the invention, that is to say that is to say comprising the specific layer 13.
- FIG. 5B schematically illustrates an example of an architecture conforming to this additional variant.
- the applications have been referenced A'i to A ' ⁇ .
- ATSDA Dedicated and Autonomous Script Translator Agent
- this agent can be either the "WEB” 232al agent, with double capacity, or an "ATSDA” agent, unique for the whole system, or the "APDU” agent 2010a, with a double capacity, or again, as illustrated in FIG. 5B, a plurality of "ATSDA” agents, referenced ATS'l to ATS'n.
- each "ATSDA” agent is associated with a single application.
- the terminal 1 does not undergo any modification of architecture and it can communicate either with smart cards comprising non-conventional applications or with entirely conventional smart cards.
- the smart card 2a itself comprises the conventional protocol layers, it is possible to store therein, both conventional applications, of the "CGA" type, accessible according to the process explained with reference to FIG. 5A or by a conventional terminal, and unconventional applications, accessible only by the variant of the method which has just been explained.
- FIG. 5C only the components of the smart card part 2a have been shown, it being understood that the terminal must necessarily have an architecture in accordance with the invention (see FIG. 2, for example) in order to be able to benefit from these advantageous features. It is indeed necessary to use the "WEB" server function offered by the smart card 2a, according to one of the characteristics of the method of the invention. To do this, the terminal must therefore include the specific layer 13 ( Figure 2).
- the general architecture of the smart card 2a is similar to that described with reference to FIG. 5A, and the common components will only be re-described as necessary.
- a piece of software 7 the function of which is to monitor downloads. It should be understood that the "downloader” 6 and “download monitoring” 7 functions can be confused by modifying the piece of software 6.
- the additional piece of software 7 "warns" the order manager "APDU” when it detects the download of a new application, the Aj application in this case. The latter then saves this modification. He can therefore now send the Aj application.
- the specific layer is updated, in particular the component 231a, configuration manager of the smart card 2a. It is further necessary to update the translating agent "ATS", “ATSD”, or “ATSDA”, as the case may be, if it is a single agent, or to create a new ATSj, associated with the new Aj application. The information required for this update is downloaded at the same time as the new Aj application.
- Updates or deletions of applications can be done using the same mechanism.
- the smart card 2a When the smart card 2a is again connected to a terminal according to the invention, the latter can be notified of the new possibilities of the smart card or of modifications, by sending a "HTLM" page, similarly to what has been described with reference to FIG. 5A.
- a specific application is provided in the smart card 2, which will be referenced by AQ convention, associated with a dedicated script translator ATSo.
- the translation can also be carried out centrally, as previously indicated ("WEB" agent, etc.).
- This Ao application is assigned the role of downloading and monitoring downloaded, modified or deleted applications.
- 1 • ATSo translator agent interacting with the Ao application, generates a PMAJ page, which will be called update page.
- This can be in the form of a menu indicating the applications present in the smart card 2a, with possibly information on their version and / or the date of downloading or modification, menu transmitted automatically or on request. of browser 10 of terminal 1.
- the downloading, updating or deletion of applications can be carried out directly from the browser 10, using the "WEB" server function of the smart card 2a.
- the necessary data are transmitted by exchanges between the terminal 1 and the smart card 2a, according to the usual process.
- the Ao application then takes care of updating the configuration information of the smart card 2a, in particular by interacting on the "APDU" order manager (not shown in FIG. 5D), as well as possibly updating or create the script translator associated with a new application, or a modified application.
- the "APDU" order manager can then send the new downloaded application.
- the Ao application and its script translator therefore constitutes a complete service for updating applications, an additional service offered by the smart card 2a. It should be clear that this update service remains compatible with the existing one.
- the smart cards 2a can continue to be downloaded from an external device EXT, on the other hand, the applications downloaded or updated by means of the browser 10, can be of a conventional "CGA" or unconventional type. In the first case, they remain compatible with the terminals of the known art.
- the invention applies in particular to an electronic purse service, but cannot in any case be limited to this single application.
