Description
PROCEDE <B>DE GESTION DE COMMANDES DANS UNE CARTE</B> La presente invention concerne un procédé de gestion commandes, au moins une commande pouvant être envoyée par moins deux lecteurs de types différents à une carte utilisateur, ladite commande étant dédiée à une zone mémoire de ladite carte, ladite carte comportant moins une zone mémoire. The present invention relates to a command management method, at least one command that can be sent by at least two readers of different types to a user card, said command being dedicated to a control card. memory area of said card, said card having less than one memory area.
L'invention trouve une application particulièrement avantageuse dans le domaine bancaire ou dans le domaine des transports, en particulier lorsque ladite carte est une carte à circuit intégré comportant aux moins deux interfaces de communication. Par exemple, la carte peut comporter une interface appelée "contact" et une autre "sans contact" définies respectivement dans les normes 7816 et 14443 éditées par 1'1S0. Une commande peut être envoyée à partir d'un lecteur avec contacts connecté directement à la carte ou par fréquences hertziennes à partir d'un lecteur sans contacts. Une commande est dédiée à une zone mémoire de la carte, couramment appelée fichier. Par exemple, dans une carte utilisateur servant de porte-monnaie électronique, une commande de mise à jour est envoyée à partir d'un lecteur sans contacts installé chez un marchand vers la carte pour débiter un montant dans un fichier solde ou à partir d'un lecteur avec contacts installé dans un point de vente d'une banque pour mettre à jour un fichier de clefs dans ladite carte, les clefs étant des données secrètes de la carte. The invention finds a particularly advantageous application in the banking field or in the transport field, in particular when said card is an integrated circuit card comprising at least two communication interfaces. For example, the card may comprise an interface called "contact" and another "contactless" defined respectively in standards 7816 and 14443 published by ISO. A command can be sent from a reader with contacts connected directly to the card or via radio frequencies from a reader without contacts. A command is dedicated to a memory area of the card, commonly called a file. For example, in a user card used as an electronic purse, an update command is sent from a merchantless reader installed at a merchant to the card to debit an amount in a balance file or from a reader with contacts installed in a point of sale of a bank to update a file of keys in said card, the keys being secret data of the card.
Bien que lesdites cartes permettent de recevoir des commandes de lecteurs types différents, elles présentent l'inconvénient de ne pas différencier commande provenant, par exemple, soit d'un lecteur sans contacts soit d'un lecteur avec contacts. Une commande est exécutée de la même manière quelque soit sa provenance. Ainsi, on peut indifféremment recharger un fichier de clefs dans la carte dudit utilisateur à partir d'un lecteur sans contacts ou à partir d'un lecteur de point de vente, ce qui pose un problème du point de vue sécuritaire, les lecteurs sans contacts étant généralement accessibles par un grand nombre de personnes et notamment par des fraudeurs. Although said cards can receive commands from different types of readers, they have the disadvantage of not differentiating command from, for example, a reader without contacts or a reader with contacts. A command is executed in the same way whatever its source. Thus, one can indifferently reload a file of keys in the card of said user from a reader without contacts or from a point of sale reader, which poses a problem from the point of view of security, the readers without contacts generally accessible by a large number of people, including fraudsters.
Aussi, un problème technique à résoudre par l'objet de la présente invention est de proposer un procédé de gestion de commandes, moins une commande pouvant être envoyée par au moins deux lecteurs de types différents à une carte utilisateur, ladite commande étant dédiée à une zone mémoire de ladite carte, ladite carte comportant moins une zone mémoire, qui permettrait de vérifier l'origine d'une commande. Also, a technical problem to be solved by the object of the present invention is to propose a command management method, less a command that can be sent by at least two readers of different types to a user card, said command being dedicated to a memory area of said card, said card having less than a memory area, which would verify the origin of a command.
Une solution au problème technique posé se caractérise, selon l'invention, en que ledit procédé de gestion de commandes comporte les étapes selon lesquelles - dans carte, on mémorise le type du lecteur envoyant ladite commande, - selon le type dudit lecteur, on contrôle que la commande envoyée est exécutable dans ladite zone mémoire de ladite carte. A solution to the technical problem posed is characterized, according to the invention, in that said command management method comprises the steps according to which - in the card, the type of the reader sending said command is memorized, - depending on the type of said reader, one checks that the command sent is executable in said memory zone of said card.
Ainsi, comme on le verra en détail plus loin, le procédé de gestion de commandes de l'invention permet, en vérifiant le type de lecteur duquel est issue la commande, d'interdire ou d'autoriser une exécution de ladite commande dans la carte selon ledit type de lecteur. Thus, as will be seen in detail below, the control management method of the invention makes it possible, by verifying the type of reader from which the command is issued, to prohibit or authorize an execution of said command in the card. according to said type of reader.
La description qui va suivre au regard des dessins annexés, donnée à titre d'exemple non limitatif, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée. The following description with reference to the accompanying drawings, given by way of non-limiting example, will make it clear what the invention is and how it can be achieved.
La figure est un schéma montrant un lecteur et une carte. The figure is a diagram showing a reader and a map.
La figure 2 montre un premier échange de données entre un lecteur et la carte de la figure 1. FIG. 2 shows a first data exchange between a reader and the card of FIG. 1.
La figure montre un deuxième échange de données entre un lecteur et la carte de la figure 1. La figure 4 est un schéma de la carte de la figure 1. The figure shows a second data exchange between a reader and the card of FIG. 1. FIG. 4 is a diagram of the card of FIG.
Sur la figure 1 est représentée une carte CARD et un lecteur R de type T donné. Une carte à circuit intégré se compose d'un corps de carte plastique dans lequel est incorporé un module électronique. Ce module comprend un élément C de commande (par exemple une unité centrale de traitement ou CPU), une mémoire de données M et un bloc B communication contact et/ou antenne destiné respectivement à connexion électrique et/ ou une liaison hertzienne avec un lecteur de carte. La mémoire de données M comporte au moins une zone mémoire Z. Avantageusement ladite mémoire M comporte plusieurs zones mémoires Z appelées fichiers. FIG. 1 shows a CARD card and a given T-type reader R. An integrated circuit card consists of a plastic card body in which is incorporated an electronic module. This module comprises a control element C (for example a central processing unit or CPU), a data memory M and a communication block B contact and / or antenna respectively for electrical connection and / or a radio link with a reader of map. The data memory M comprises at least one memory zone Z. Advantageously said memory M has several memory zones Z called files.
Lorsqu'une commande CD est envoyée par le lecteur R à la carte, dans une première étape, on mémorise le type T dudit lecteur dans la carte. Selon un mode de réalisation préférentiel, la mémorisation se fait au moyen d'un indicateur FT de type positionné dans la mémoire de données M ladite carte CARD. Ledit indicateur FT est un bit ou un octet, suivant le nombre de types de lecteurs que l'on veut différencier. Par exemple, dans le cas de deux types de lecteurs on a un bit, comme le montre figure 2. Lorsqu'une commande CD est envoyée à partir d'un lecteur avec contacts Rwc vers la carte, l'indicateur FT prend une valeur égale à un. Lorsque le lecteur est sans contacts, la valeur de l'indicateur zéro. Une commande est adressée à une zone mémoire Z de la carte CARD. When a CD command is sent by the reader R to the card, in a first step, the type T of said reader is stored in the card. According to a preferred embodiment, the storage is done by means of a type FT indicator positioned in the data memory M said CARD card. The said FT indicator is a bit or an octet, depending on the number of reader types that are to be differentiated. For example, in the case of two types of readers one has a bit, as shown in Figure 2. When a CD command is sent from a reader with contacts Rwc to the card, the flag FT takes an equal value has a. When the drive is without contacts, the value of the zero indicator. A command is addressed to a memory zone Z of the CARD card.
Dans une deuxième étape, afin d'interdire ou d'autoriser une exécution de la commande CD envoyée par un type de lecteur donné, selon un premier mode de réalisation, chaque zone mémoire Z comporte, d'une part, un ensemble CM de moyens de contrôle de commande pour chaque type de lecteur, et d'autre part, des conditions d'accès AC associées à une commande ou un groupe de commandes. Sur l'exemple de la figure 3, on a une condition d'accès AC respectivement pour les commandes de lecture CD R, d'écriture CD W et de creation de fichier CD ÇF. Préférentiellement, à chaque moyen contrôle de commande est associée une condition d'accès AC. Un moyen de contrôle est représenté par un bit appelé bit de contrôle. Dans l'exemple donné, un premier ensemble<B>CM 1</B> de bits de contrôle est associé lecteur avec contacts Rwc et un second CM2 au lecteur sans contacts Rcl. Afin d'interdire une commande de création de fichier CD CF provenant du lecteur sans contacts Rcl adressée à la zone mémoire Z1, on positionne le bit de contrôle CM2 B3 correspondant, à zéro, tandis que le bit de contrôle CM 1B3 correspondant à commande de création de fichier provenant d'un lecteur avec contacts Rwc est positionné à un. Lors de l'envoi de ladite commande de création CD CF, dans le fichier, selon la valeur de l'indicateur FT de on vérifie le bit de contrôle CM -B correspondant au type et à ladite commande envoyée. Ainsi, on contrôle que la commande envoyée par ledit lecteur est exécutable dans ladite zone mémoire de ladite carte. In a second step, in order to prohibit or authorize an execution of the command CD sent by a given reader type, according to a first embodiment, each memory zone Z comprises, on the one hand, a set CM of means control control for each type of reader, and secondly AC access conditions associated with a command or group of commands. In the example of FIG. 3, there is an AC access condition respectively for the CD R read, CD W write and CD CD file creation commands. Preferably, each control control means is associated with an access condition AC. A control means is represented by a bit called the control bit. In the example given, a first set of control bits CMB is associated with Rwc contacts and a second CM2 to the Rcl-free reader. In order to prohibit a CF CD file creation command from the contactless reader Rcl addressed to the memory zone Z1, the corresponding CM2 control bit B3 is set to zero, while the control bit CM 1B3 corresponding to the control command file creation from a reader with contacts Rwc is set to one. When sending said creation command CD CF, in the file, according to the value of the indicator FT of one checks the control bit CM -B corresponding to the type and to said command sent. Thus, it is checked that the command sent by said reader is executable in said memory zone of said card.
Enfin, dans une dernière étape, si le contrôle est positif, on vérifie les conditions d'accès AC à ladite zone mémoire Z liées à ladite commande et, le cas échéant, on exécute ladite commande CD. Dans le cas contraire, on rejette la commande. Dans l'exemple de la figure 3, l'indicateur FT de type est à zéro, par suite la commande de création de fichier CD ÇF provient d'un lecteur sans contacts Rcl. On contrôle l'ensemble CM2 des moyens de contrôle correspondants au lecteur sans contacts Rcl. Le bit correspondant CM2 B3 à la commande de création de fichier CD CF est égal à zéro. Le contrôle est négatif, par suite, on rejette la commande de création CD CF. Finally, in a last step, if the control is positive, it verifies the AC access conditions to said memory zone Z related to said command and, if necessary, executes said command CD. Otherwise, we reject the order. In the example of FIG. 3, the type flag FT is zero, as a result the file creation command CD FF is from a reader without contacts Rc1. CM2 is controlled control means corresponding to the reader without contacts Rcl. The corresponding CM2 bit B3 at the CD CF file creation command is equal to zero. The control is negative, therefore, the creation command CD CF is rejected.
Selon un second mode de réalisation, chaque fichier comporte, pour chaque type de lecteur un ensemble de conditions d'accès AC associées à une commande ou un groupe de commandes. Par exemple, sur la figure 4, la carte CARD comporte un fichier Z1 comprenant un premier ensemble de conditions d'accès ACwc relatif au lecteur avec contacts Rwc et un second ensemble de conditions d'accès ACcl relatif au lecteur sans contacts Rcl. Ainsi, selon la valeur de l'indicateur FT de type, on contrôle que la commande CD envoyée est executable dans ladite zone mémoire Z de ladite carte, et ce au moyen desdites conditions d'accès AC associées. Dans l'exemple de la figure 4, on interdit l'exécution de la commande création de fichier _CF dans le fichier relativement au lecteur sans contacts Rcl en positionnant la condition d'accès associée, à la valeur NEVER. Avantageusement, à chaque ensemble de conditions d'accès, on associe un ensemble de clefs différent autres ensembles. Ainsi, d'après l'exemple, pour exécuter une commande de lecture CD_R provenant d'un lecteur avec contacts, on présente une première clef KEY1, tandis que pour un lecteur sans contacts, présente une deuxième clef KEY2. According to a second embodiment, each file comprises, for each type of reader, a set of AC access conditions associated with a command or a group of commands. For example, in FIG. 4, the card CARD includes a file Z1 comprising a first set of access conditions ACwc relating to the reader with contacts Rwc and a second set of access conditions ACc1 relating to the reader without contacts Rc1. Thus, depending on the value of the type indicator FT, it is checked that the command CD sent is executable in said memory zone Z of said card, and this by means of said associated AC access conditions. In the example of FIG. 4, it is forbidden to execute the command creation of file _CF in the file relative to the reader without contacts Rcl by setting the associated access condition to the value NEVER. Advantageously, for each set of access conditions, a set of different keys is associated with other sets. Thus, according to the example, to execute a read command CD_R coming from a reader with contacts, a first key KEY1 is presented, while for a reader without contacts, presents a second key KEY2.
Ainsi grâce à l'invention décrite ci-dessus, on gère de façon sécuritaire les accès à la carte en interdisant à un certain type de lecteur l'accès, par l'intermédiaire d'une commande, à une ou plusieurs zones mémoires de ladite carte CARD. Thus, thanks to the invention described above, access to the card is securely managed by forbidding a certain type of reader access, via a command, to one or more memory areas of said CARD card.
