Description
L'invention concerne le domaine des dispositifs automatiques de paiement, du type terminal, borne, horodateur, mis à la disposition du public et plus particulièrement la protection de ces dispositifs contre les attaques frauduleuses.The invention relates to the field of automatic payment devices, terminal type, terminal, time stamp, made available to the public and more particularly the protection of these devices against fraudulent attacks.
Étant isolés et aptes à contenir de l'argent, ces dispositifs de paiement sont susceptibles de subir des attaques aussi bien au niveau du dispositif lui-même que de ses moyens de communication et doivent donc être équipés de moyens de dissuasion.Being isolated and able to contain money, these payment devices are susceptible to attacks both on the device itself and its means of communication and must therefore be equipped with deterrents.
D'une manière générale ces moyens de dissuasion doivent avoir pour fonctions d'une part de détecter une éventuelle attaque et d'autre part de signaler cette attaque.In general, these deterrents must have the function of detecting a possible attack and of signaling the attack.
On connaît déjà des bornes publiques de paiement destinées à être installées dans les rues d'une ville et disposant de moyens de dissuasion contre les attaques.We already know public payment terminals intended to be installed in the streets of a city and having deterrents against attacks.
Chacune de ces bornes connues dispose d'une connexion au réseau téléphonique et de moyens de détection d'une éventuelle attaque.Each of these known terminals has a connection to the telephone network and means for detecting a possible attack.
Lorsqu'une attaque est perpétrée contre une de ces bornes, celle-ci compose le numéro de téléphone d'un central de surveillance et lui envoie un signal d'alerte.When an attack is perpetrated against one of these terminals, it dials the telephone number of a central surveillance and sends an alert.
Ces bornes connues présentent un certain nombre d'inconvénients.These known terminals have a number of disadvantages.
En effet, l'existence d'un tel moyen d'alerte étant connue, les fraudeurs tendent à couper toute communication entre la borne et le central de surveillance en utilisant des dispositifs adaptés tels que des dispositifs de brouillage des signaux GSM.Indeed, the existence of such a means of alert being known, fraudsters tend to cut any communication between the terminal and the central monitoring using suitable devices such as scrambling devices GSM signals.
Le but de l'invention est de remédier aux inconvénients de l'art antérieur en fournissant une solution de dissuasion contre les attaques de terminaux qui soit tout à la fois fiable et peu coûteuse.The object of the invention is to overcome the disadvantages of the prior art by providing a deterrent solution against terminal attacks that is both reliable and inexpensive.
Selon un premier objet de l'invention, celle-ci porte sur un procédé de surveillance d'une pluralité de terminaux, notamment d'horodateurs, dans lequel au moins des premier et second terminaux sont équipés de moyens de communication permettant aux dits premier et second terminaux de communiquer entre eux et avec un central de surveillance.According to a first object of the invention, it relates to a method of monitoring a plurality of terminals, in particular time stamps, in which at least first and second terminals are equipped with communication means allowing said first and second terminals to communicate with each other and with a central monitoring.
Selon une définition générale de l'invention, le procédé comprend un protocole de surveillance selon lequel les premier et second terminaux doivent s'appeler, de préférence mutuellement et à une cadence prédéterminée, et en cas d'absence d'appel et/ou de non-réponse de la part du second terminal, ledit premier terminal est apte à appeler le central de surveillance pour l'informer de la situation anormale concernant le second terminal.According to a general definition of the invention, the method comprises a monitoring protocol according to which the first and second terminals must be called, preferably mutually and at a predetermined rate, and in the absence of a call and / or nonresponse from the second terminal, said first terminal is able to call the central monitoring to inform him of the abnormal situation concerning the second terminal.
La mise en oeuvre de ce procédé amène chacun des terminaux à surveiller ses voisins et à être lui-même surveillé par ses voisins.The implementation of this method causes each of the terminals to monitor its neighbors and to be itself monitored by its neighbors.
Au niveau du parc de terminaux, une surveillance interne a donc lieu, sans l'intervention du central de surveillance.At the level of the terminal park, internal monitoring therefore takes place without the intervention of the central monitoring station.
Cette surveillance a lieu à l'aide de communications inter-terminaux ne nécessitant pas de frais d'opérateur de télécommunication.This monitoring takes place using inter-terminal communications that do not require telecommunication operator fees.
Une communication téléphonique vers le central de surveillance n'est déclenchée que lorsqu'une anomalie s'est effectivement produite, c'est-à-dire lorsque l'un des terminaux détecte l'absence de réponse de l'un de ses voisins ou bien lorsque l'un des terminaux détecte une tentative d'attaque à son encontre.A telephone call to the central monitoring station is triggered only when an anomaly has actually occurred, that is to say when one of the terminals detects the absence of response from one of its neighbors or well when one of the terminals detects an attempted attack against it.
Selon un autre mode de réalisation, le protocole de surveillance comprend en outre une étape selon laquelle chacun des terminaux signale une éventuelle attaque frauduleuse à son encontre en contactant directement le central de surveillance ou en contactant un terminal voisin qui se chargera de contacter le central de surveillance.According to another embodiment, the monitoring protocol also comprises a step according to which each of the terminals reports a possible fraudulent attack against it by directly contacting the central monitoring station or by contacting a neighboring terminal which will be in charge of contacting the central office. monitoring.
D'autre part, les communications entre les terminaux peuvent être effectuées au moyen d'un réseau local radioélectrique.On the other hand, the communications between the terminals can be carried out by means of a radio local area network.
De plus, les communications entre un terminal et le central de surveillance peuvent être effectuées au moyen d'un réseau téléphonique ouvert au public.In addition, communications between a terminal and the central monitoring can be performed through a telephone network open to the public.
Selon un deuxième objet de l'invention, celle-ci vise un dispositif de surveillance d'une pluralité de terminaux, notamment d'horodateurs, du type comprenant au moins des premier et second terminaux voisins l'un de l'autre et équipés de moyens de communication permettant auxdits premier et second terminaux de communiquer entre eux et avec un central de surveillance, les premier et second terminaux devant s'appeler mutuellement à une cadence choisie et le dispositif comprenant des moyens de surveillance logés dans au moins le premier terminal et aptes en cas d'absence d'appel et/ou de non-réponse de la part du second terminal à appeler le central de surveillance pour l'informer de la situation anormale concernant le second terminal.According to a second object of the invention, it relates to a device for monitoring a plurality of terminals, in particular time stamps, of the type comprising at least first and second terminals neighboring one another and equipped with communication means allowing said first and second terminals to communicate with each other and with a central monitoring station, the first and second terminals to mutually call each other at a selected rate and the device comprising monitoring means housed in at least the first terminal and suitable in case of absence of call and / or non-response from the second terminal to call the central monitoring to inform him of the abnormal situation concerning the second terminal.
L'invention a également pour objet un terminal comportant des moyens de communication permettant de communiquer avec au moins un second terminal et avec un central de surveillance et des moyens de commande assurant l'émission d'appels à destination dudit second terminal et des moyens de surveillance aptes en cas d'absence d'appel et/ou de non-réponse de la part du second terminal à appeler le central de surveillance (4) pour l'informer de la situation anormale concernant le second terminal.The invention also relates to a terminal comprising communication means for communicating with at least one second terminal and with a central monitoring and control means ensuring the transmission of calls to said second terminal and means of monitoring able in case of absence of call and / or non-response from the second terminal to call the central monitoring (4) to inform him of the abnormal situation concerning the second terminal.
Selon un autre mode de réalisation, ledit terminal doit appeler au moins un terminal voisin à une cadence choisieAccording to another embodiment, said terminal must call at least one neighboring terminal at a chosen rate.
Selon un autre mode de réalisation particulier, le terminal comprend en outre des moyens de détection d'attaques frauduleuses et est apte à signaler une éventuelle attaque à son encontre en contactant directement le central de surveillance ou en contactant un terminal voisin qui se chargera de contacter le central de surveillance.According to another particular embodiment, the terminal further comprises means for detecting fraudulent attacks and is able to signal a possible attack against it by directly contacting the central surveillance or by contacting a neighboring terminal which will contact the central surveillance.
Les moyens permettant audit terminal de communiquer avec les autres terminaux peuvent comprendre un dispositif radioélectrique émetteur-récepteur.The means enabling said terminal to communicate with the other terminals may comprise a transceiver radio device.
Les moyens permettant audit terminal de communiquer avec le central de surveillance peuvent comprendre des moyens de raccordement à un réseau téléphonique ouvert au public.The means for said terminal to communicate with the central monitoring may include connection means to a telephone network open to the public.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description donnée ci-après et des dessins dans lesquels :
- la figure 1 représente une paire d'horodateurs et un central de surveillance, un premier horodateur recevant un appel d'un second horodateur ;
- la figure 2 représente une paire d'horodateurs et un central de surveillance, un premier horodateur effectuant un appel vers un second horodateur.
- FIG. 1 represents a pair of time stamps and a monitoring station, a first time clock receiving a call from a second time stamp;
- Figure 2 shows a pair of timestamps and a monitoring center, a first time stamp making a call to a second time stamp.
L'ensemble représenté sur les figures 1 et 2 est composé d'un parc d'horodateurs réduit au minimum pour des raisons de clarté (deux horodateurs 1, 2 seulement), d'un réseau téléphonique 3 et d'un central de surveillance schématisé par un micro-ordinateur 4.The assembly represented in FIGS. 1 and 2 is composed of a fleet of parking meters reduced to a minimum for the sake of clarity (two
Dans l'exemple décrit, le réseau téléphonique 3 est un réseau sans-fil tel que le réseau européen GSM mais peut être un quelconque réseau de communication, par exemple ouvert au public tel que le réseau filaire RTC et analogues.In the example described, the telephone network 3 is a wireless network such as the European GSM network but can be any communication network, for example open to the public such as the RTC wired network and the like.
Le central de surveillance 4 dispose de moyens de traitement informatique reliés au réseau téléphonique 3 et aptes à recevoir et traiter des appels provenant d'un horodateur 1 ;2.The monitoring station 4 has computer processing means connected to the telephone network 3 and able to receive and process calls from a time stamp 1; 2.
Les horodateurs 1, 2 composant le parc sont équipés de moyens informatiques de traitement de l'information et sont également équipés de moyens de liaison au réseau téléphonique 3 aptes à appeler le central de surveillance 4 et à lui transmettre un signal d'alerte.The
Le signal d'alerte se présente comme un code binaire élaboré par l'équipement informatique d'un horodateur 1 ;2 et transmis sous forme modulée via le réseau téléphonique 3 vers le central de surveillance 4.The warning signal is presented as a binary code developed by the computer equipment of a time clock 1; 2 and transmitted in modulated form via the telephone network 3 to the central monitoring station 4.
Lors de la réception du signal d'alerte, le central de surveillance 4 démodule le signal reçu pour obtenir le code binaire initial et l'identifie comme étant un signal d'alerte.Upon receiving the alert signal, the monitoring station 4 demodulates the received signal to obtain the initial binary code and identifies it as an alert signal.
Il est nécessaire à cet effet d'établir préalablement un protocole de communication entre le central téléphonique 4 et les horodateurs 1, 2 pour définir le code binaire correspondant à un signal d'alerte.It is necessary for this purpose to establish beforehand a communication protocol between the central office 4 and the
De la même manière, d'autres codes correspondant à d'autres informations qui pourraient être transmises entre le central de surveillance 4 et les horodateurs 1, 2 peuvent être définis.In the same manner, other codes corresponding to other information that could be transmitted between the central monitoring station 4 and the
Les horodateurs 1, 2 sont d'autre part équipés de moyens de transmission radioélectriques rendant chaque horodateur apte à communiquer avec tous les horodateurs se trouvant dans la zone de couverture de ses moyens de transmission.The
Par exemple, les moyens de transmission sont constitués par des cartes réseau répondant aux normes de transmission sans-fil IEEE 802.111b permettant aux horodateurs de communiquer entre eux en employant le protocole TCP/IP, un tel protocole n'est donné qu'à titre illustratif et n'est pas limitatif de la présente invention. La communication entre les horodateurs s'effectuent de préférence en utilisant un réseau de type WLL (wireless local loop) c'est-à-dire un réseau radioélectrique sans fil. Différentes gammes de fréquences sont utilisables et notamment les fréquences infrarouges, protocole Blue Tooth par exemple. L'intérêt d'un tel mode de communication est qu'il est gratuit.For example, the transmission means consist of network cards meeting the IEEE 802.111b wireless transmission standards enabling the pay and display machines to communicate with each other by using the TCP / IP protocol, such a protocol is given only as illustrative and not limiting of the present invention. The communication between the time stamps is preferably carried out using a wireless local loop (WLL) type network, that is to say a wireless radio network. Different ranges of frequencies are usable and in particular the infrared frequencies, protocol Blue Tooth for example. The interest of such a mode of communication is that it is free.
L'ensemble qui vient d'être décrit fonctionne de la manière indiquée ci-après.The assembly that has just been described operates in the manner indicated below.
Le parc d'horodateurs 1, 2 est installé dans les rues d'une ville de manière que chacun se trouve dans la zone de couverture des moyens de transmission électromagnétiques d'au moins un autre horodateur.The
En fonctionnement normal, chaque horodateur contacte au moins son voisin le plus proche dont les coordonnées lui ont été préalablement communiquées pour vérifier qu'il fonctionne bien et est, par conséquent, lui-même contacté par ses voisins.In normal operation, each parking meter contacts at least its nearest neighbor whose coordinates were previously communicated to verify that it works well and is, therefore, himself contacted by his neighbors.
De même que pour la communication avec le central de surveillance 4, il est nécessaire de définir un protocole par lequel les horodateurs vérifieront mutuellement leur bon fonctionnement.As for the communication with the central monitoring 4, it is necessary to define a protocol by which the timestamps mutually check their proper operation.
A ces fins, un code d'appel et un code de confirmation sont définis. Lorsqu'il contacte l'un de ses voisins, chaque horodateur envoie le code d'appel et attend le code de confirmation pour considérer que l'horodateur contacté fonctionne correctement.For these purposes, a call code and a confirmation code are defined. When contacting one of its neighbors, each time stamp sends the call code and waits for the confirmation code to consider that the contacted time stamp is functioning correctly.
Par conséquent, chaque horodateur doit également envoyer le code de confirmation à chacun des horodateurs le sollicitant par l'envoi du code d'appel.Therefore, each time stamp must also send the confirmation code to each of the time stamps requesting it by sending the call code.
Par ailleurs et pour limiter la consommation d'énergie, seuls les moyens de transmission radioélectriques sont alimentés pendant les périodes de veille, assurant ainsi les fonctions de vérifications mutuelles des terminaux sans dépenses d'énergie qui ne soit pas absolument nécessaire.Moreover, and in order to limit energy consumption, only the radio transmission means are powered during standby periods, thus ensuring the functions of mutual verification of terminals without energy expenditure which is not absolutely necessary.
La figure 1 représente un horodateur 2 effectuant un envoi du code d'appel vers un horodateur 1 voisin et la figure 2 représente une situation similaire, l'horodateur 1 envoyant cette fois-ci le code de confirmation en réponse à l'horodateur 2.FIG. 1 represents a
Dans le cas où l'horodateur 2 est défaillant, l'envoi du code d'appel illustré à la figure 1 ne se produit pas et l'horodateur 1, qui attend périodiquement le code d'appel de la part de l'horodateur 2, détecte le silence de cet horodateur 2 et interprète cela comme une défaillance de l'horodateur 2.In the case where the
L'horodateur 1 téléphone alors au central de surveillance 4 et lui transmet le code d'alerte en identifiant l'horodateur 2 resté muet.The time stamp 1 then phones the central monitoring 4 and transmits the alert code identifying the
De même, dans le cas où l'horodateur 1 est cette fois-ci défaillant, l'envoi du code de confirmation illustré à la figure 2 ne se produit pas et l'horodateur 2, qui attend le code de confirmation de la part de l'horodateur 1, détecte le silence de cet horodateur 1 et interprète cela comme une défaillance de l'horodateur 1.Similarly, in the case where the time stamp 1 is this time failing, the sending of the confirmation code illustrated in Figure 2 does not occur and the
L'horodateur 2 téléphone alors au central de surveillance 4 et lui transmet le code d'alerte en identifiant l'horodateur 1 resté muet.The
D'autre part, chaque horodateur est également équipé de moyens de détection d'attaques aptes à détecter des attaques physiques tel qu'un ensemble de capteurs disposés sur les composants de l'horodateur et aptes également à détecter des attaques sur ses voies de communications tels que des dispositifs de sécurité informatique rendant compte d'une tentative de brouillage électromagnétique ou de connexion frauduleuse à l'équipement informatique de l'horodateur.On the other hand, each time stamp is also equipped with attack detection means able to detect physical attacks such as a set of sensors arranged on the components of the time stamp and also able to detect attacks on its communication channels. such as computer security devices reporting an attempt to electromagnetic interference or fraudulent connection to the computer equipment of the time stamp.
Dans le cas où un horodateur détecte une telle attaque sur lui-même, cet horodateur a la possibilité d'une part d'appeler lui-même le central de surveillance 4 pour se déclarer victime d'une attaque ou bien, d'autre part de transmettre un signal d'alerte à l'un de ses voisins qui contactera le central de surveillance.In the case where a time stamp detects such an attack on itself, this time stamp has the possibility on the one hand to call himself the monitoring station 4 to declare himself the victim of an attack or else to transmit an alert signal to one of his neighbors who will contact the central monitoring.
Ces possibilités peuvent être utilisées en combinaison pour un maximum de sécurité, le central de surveillance 4 étant alerté même si l'un des deux moyens de communication de l'horodateur attaqué est mis hors service par l'attaque.These possibilities can be used in combination for maximum security, the monitoring station 4 being alerted even if one of the two means of communication of the attacked time stamp is disabled by the attack.
L'invention mise en oeuvre permet d'obtenir les avantages suivants :
- une réduction des coûts de fonctionnement d'un parc d'horodateurs par la limitation au strict nécessaire des appels payants vers le central de surveillance et l'utilisation alternative des communications inter-terminaux, celles-ci étant sans frais dans la mesure où elles ne font pas intervenir d'opérateur téléphonique ;
- les attaques ciblées sur les moyens de communications des horodateurs sont également détectées ;
- les dépenses en énergie des terminaux sont minimisées par l'alimentation sélective des composants autorisant la mise en service uniquement des moyens de transmission inter-terminaux pendant les périodes de veille;
- une réactivité quasi-immédiate aux attaques, chaque terminal pouvant lui-même signaler une attaque à son encontre.
- a reduction in the operating costs of a parking meter park by limiting the need for pay calls to the central monitoring station and the alternative use of inter-terminal calls, which are free of charge insofar as they do not do not involve a telephone operator;
- targeted attacks on the means of communication of pay and display machines are also detected;
- the energy expenditure of the terminals is minimized by the selective power supply of the components allowing only inter-terminal transmission means to be put into service during the waking periods;
- an almost immediate response to attacks, each terminal can itself report an attack against him.
