Definitions

  • the invention relates to the field as access control. It relates more particularly to an access control procedure and access control system based on an identification procedure (actually: authentication method).
  • Identification systems are used in different applications such as access control prepaid card systems, data acquisition systems, etc.
  • the wireless information transmissions for example via radio frequency signals, or microwaves (eg via GSM) are becoming increasingly important. Due to the comparatively large range, the potential problem of manipulation arises. Thus, for example, by means of a distance from a data exchange point (writing and / or reading device of a locking system of a prepaid card reader, etc.) a transmitter / receiver of a manipulator be set up by means of a so-called "man-in-the-middle" Attack or another vulnerability of the exchange protocol used exploiting exploitation is performed.
  • capacitive-resistive coupling also called 'capacitive coupling' or 'PAN coupling'
  • 'PAN coupling' capacitive-resistive coupling
  • a disadvantage of the capacitive-resistive coupling is the very low data transmission rate of the information transmission, which is generally achievable. This is because the communication device is generally set up to allow signal transmission through the human body. This prohibits high frequencies and high amplitudes.
  • a key is transmitted via the PAN coupling, which transmitted the in the subsequent communication via the RF channel
  • the invention is characterized essentially by the fact that for the access control in a first step, a wireless radio link (here are expressly meant in addition to radio frequencies communication via microwave frequencies or other frequencies of the electromagnetic spectrum) between the object to the access is sought, and an access control medium (mobile phone, other electronic device, smart card, etc.) is established.
  • an authentication procedure is initially performed, in which the access authorization of the access control medium is checked.
  • a temporary access code is sent from the object to the access control medium and sent back by this to the object, possibly in a modified form.
  • the capacitive-resistive coupling is used either for the return of the - optionally modified - access code to the object or possibly for the transmission of the access code to the access control medium; in the other direction the signal is sent via the wireless connection.
  • the object is a door with a mechatronic Locking device, which is in communication with a - optionally integrated in the locking device - writing and / or reading device, which in turn has means for communicating over the wireless connection and for receiving and / or transmitting capacitive-resistive signals.
  • the release of the object in this case corresponds to the mechatronic unlocking of the door.
  • the authentication method is any method of determining whether the access control medium is authorized to access the object. This can be done through a simple query of codes that must be present on the access control medium, over more complex, secure procedures. In particular, it is possible to carry out the authentication method in a manner known per se from the prior art or by means of a commercially available system whose protocol does not necessarily have to be known. In any case, the authentication method preferably provides a yes / no answer to the question whether the access control medium authorizes access in the present situation. Only if the answer is yes is a temporary access code generated and transmitted to the access control medium.
  • the access control medium constantly repeats the temporary access code or the data packet derived therefrom via the transmitter
  • a pair of electrodes present in the access control medium is supplied with a corresponding signal.
  • a receiver electrode e.g., a door handle, which is preferably as a receiver electrode or as part of the receiver electrode of the capacitive-resistive
  • the reception of the signal by the capacitive-resistive coupling receiver starts; wherein the signal path may pass through the user's body when carrying the access control medium in the pocket.
  • the data transmitted with the capacitive-resistive coupling may consist of a temporary access code (containing no access control medium-specific data) which may have been modified with a simple access control medium-specific operation. Adding an ID or other simple string is not excluded.
  • a security against manipulation consists on the one hand in the security of the selected wireless connection; available procedures often include one
  • the temporary access code is transmitted via the capacitive-resistive coupling-permanently-and then sent back via the existing wireless connection; it is easily possible for the recipient to verify that it comes from the same sender with which the successful authentication process was previously performed.
  • the method according to the invention brings practically no time delays which are recognizable to the user, since the back transmission of the optionally modified access code can take place immediately after its reception via the capacitive-resistive coupling, namely via the already established wireless connection.
  • Bluetooth Low Energy standard previously known under the name "Wibree.”
  • Wibree the Bluetooth Low Energy standard
  • the use of this comparatively short-range (approximately 10 m signal range) technology is advantageous in terms of safety because of the short range
  • they favor the "access control" application for the following reason: Doors in buildings are often not wired, and wiring would be very time consuming. Therefore, such stand-alone devices rely on battery power, which is undesirable for practical reasons when these batteries need to be replaced at high speeds, so the very energy-efficient Bluetooth Low Energy technology is actually the receiver for communications between and near sensors
  • the use of "normal” Bluetooth is likewise possible, with the disadvantage that the power consumption of such a system is higher.
  • the access control medium is preferably a portable device, for example a mobile telephone. In such is generally enough power available.
  • the access control medium assumes the role of "master" in Kiruninkation Bluetooth or Bluetooth Low Energy, ie the initialization of the connection is based on the access control medium.
  • maintenance data is transmitted from the writing and / or reading device (the door) to the access control medium, for example battery life data etc.
  • the non-wired write and / or Reading device via the access control medium trigger a warning signal or draw attention in another suitable manner to be remedied.
  • the procedure according to the invention is particularly suitable for applications in which the access control medium does not have to be actively handled by the user, for example, but can remain in his pocket.
  • the kapitizitiv-resistive coupling is then preferably primarily through the body of the user, which acts as a - bad - electrical conductor. Therefore, for the capacitive-resistive coupling, the ultra-wideband signal transmission using the frequency spreading method is therefore particularly preferred. This can cause the current amplitudes flowing through the body to be very small.

Abstract

L’invention se caractérise essentiellement en ce que, dans une première étape, en vue du contrôle d’accès, une liaison radio sans fil (ce qui sous-entend de façon explicite, outre la communication par radiofréquences, la communication au moyen de fréquences micro-ondes ou d’autres fréquences de spectre électromagnétique) est établie entre l’objet, auquel on cherche à accéder, et un moyen de contrôle d’accès (téléphone mobile, autre appareil électronique, carte à puce etc.). Au moyen de cette liaison sans fil, on effectue d’abord un procédé d’authentification dans lequel l’autorisation d’accès du moyen de contrôle d’accès est vérifiée. Un code d’accès provisoire est ensuite envoyé de l’objet au moyen de contrôle d’accès et renvoyé par celui-ci à l’objet, éventuellement sous une forme modifiée. Le couplage capacito-résistif est utilisé pour le renvoi du code d’accès – le cas échéant, modifié – à l’objet ou éventuellement pour l’envoi du code d’accès au moyen de contrôle d’accès. Le signal est envoyé au moyen de la liaison sans fil dans l’autre direction.
