Definitions

  • the invention relates to a method for the wireless transmission of data, such as e.g. Access authorization data, user identification data, key data or the like, from, to and / or between locking devices or their components and a locking device with means for wireless transmission and / or reception of data, such as e.g. Access authorization data, user identification data, key data or the like, in particular for carrying out the method according to the invention.
  • data such as e.g. Access authorization data, user identification data, key data or the like
  • Locking devices are known in which access authorization data, user identification data, key data or the like, for example, are wirelessly transmitted between an electronic key and a lock.
  • the encryption algorithm can, depending on the quality of the algorithm, generally be determined using a corresponding amount of computation. Listening to the data transmission is only excluded if, as can be the case with RFID technology, for example, with appropriate design, the data transmission between the transponder and the reading device can only take place over a distance of a few centimeters, which in turn reduces the user friendliness , For example, the user is forced to take the electronic key to lock a lock out of a pocket or the like, and bring it very close to the reading device of the lock. It would be much more comfortable, however, if the user could leave the electronic key in his pocket and the lock prepares for opening when approaching, before the doorknob is within reach.
  • the invention therefore aims to improve the method and the device of the type mentioned in that even at a higher range, the security of the data transmission between the closing technical Facilities is not affected. Furthermore, the invention aims to increase the transmission rate and to reduce the energy consumption for data transmission.
  • the invention provides that the data is transmitted over a carrier frequency of 0.1 to 10 terahertz.
  • Terahertz radiation also known as sub-millimeter waves, penetrates many materials and tissues, but due to the low energy of the photons, it is non-ionizing, making its use harmless to humans.
  • terahertz radiation is strongly absorbed by some metals and especially by water, which is why humans and animals are good absorbers of terahertz radiation.
  • this property can be exploited, for example, in data transmission in locking devices, such that a person who approaches an openable door with an electronic key automatically receives the data to be transmitted to third parties who are behind him. shields.
  • the terahertz radiation thereby spreads much more directed than in conventional data communication. It is therefore much more difficult for unauthorized persons to receive the transmitted data unnoticed and to use it for harmful purposes.
  • the directional propagation of the terahertz radiation also ensures that the data is sent only to the respectively desired device, which is advantageous, for example, in hotel locks or locking systems in large buildings and the like, in which a plurality of lockable doors are arranged at a small distance from one another are.
  • the technical effort can be significantly reduced if the data sent by the electronic key identification data are made available only the lock of the desired door, but not a variety of adjacent doors in which due to the receipt of identification data also triggered an identification test becomes.
  • Another advantage of the invention is that substances such as e.g. Plastic, paper and clothing for terahertz radiation are mostly transparent. In the field of locking technology, this can be useful because an electronic key does not have to be held to the door, but it can be e.g. in a suitable container or under clothing.
  • the transmission rate is much higher, so much more data can be transmitted in a given period of time than with conventional systems.
  • the power consumption can be significantly reduced.
  • the method according to the invention is preferably carried out such that the data are transmitted via a carrier frequency of at least 0.5, preferably at least 1, preferably at least 2 terahertz. It has been shown that the positive effects described above can already be observed at these frequencies.
  • the method is carried out so that the data are transmitted over a carrier frequency of at most 8, preferably at most 5 terahertz.
  • a suitable choice of the carrier frequency thus depends on the amount of data to be transmitted and the time available for the transmission.
  • the method is performed so that the data are transmitted via electromagnetic waves. The use of electromagnetic waves creates the opportunity to use small-scale electronic components.
  • Another preferred implementation of the method is that the data is transmitted between an electronic key and a locking device.
  • the data is transmitted between an electronic key and a locking device.
  • a locking device due to the use of terahertz radiation and the setting of a lower transmission power, which on the one hand the potential positions for eavesdropping are severely restricted and on the other hand, even this area is further reduced by the shielding by the body of the key holder, a special high security of the locking system can be ensured.
  • the security of the transmission can be further increased in a preferred manner in that the data is transmitted in encrypted form.
  • the potential range for undesired intervention can be further reduced, further increasing the security of the transmission.
  • the method is performed so that the data is transmitted or received via at least two antennas.
  • the key carried by the person can be spatially localized, which makes it possible to determine, for example, whether the person stands in front of or behind a door to open it, and on the other hand, how many Transponders or listening devices are within reach. This can prevent that important key data is transmitted in the presence of a listening device at all.
  • a closing device is provided with means for wireless transmission and / or reception of data, e.g. Access authorization data, user identification data, key data or the like.
  • data e.g. Access authorization data, user identification data, key data or the like.
  • the means for wireless transmission or reception of the data over a carrier frequency of 0.1 to 10 terahertz are formed.
  • the means for wireless transmission or reception can be easily incorporated into masonry, door frames, etc., since materials such as wood, stone o.a. can be penetrated by the terahertz waves.
  • the reception or transmission angle can be further reduced or defined more precisely.
  • Thicker walls may attenuate the terahertz signal, and the amount of attenuation may be adjusted by selecting the frequency within the terahertz band.
  • This possibility does not exist in conventional data transmission, which has the disadvantage that the signal is often distributed over a large area, even through walls, and thus the locking devices can not or only with difficulty and often inadequately recognize whether the person actually is in the immediate vicinity of the door to be opened or is located only in the reception area of the transmitter. It may happen that a door is erroneously released to an unauthorized person located near the door when the locking device can receive the signal from an authorized person located at a greater distance from that door. This problem of some radio systems can be handled much easier at terahertz frequencies.
  • the device according to the invention is developed so that the means for wireless transmission or reception of the data over a carrier frequency of at least 0.5, preferably at least 1, preferably at least 2 terahertz are formed and that the means for wireless transmission or reception the data are formed over a carrier frequency of at most 8, preferably at most 5 terahertz, wherein the chosen frequency naturally depends on the field of application.
  • the security of the transmission can be further increased. Due to the relatively large transferable data volumes, the encryption algorithms can also be very complex or longer keys can be transmitted, thus greatly reducing the possibilities of unauthorized decryption.
  • the device is developed in such a way that the means for transmitting the data have at least one directional antenna. Directed transmission and screening by the key holder can further reduce the potential listening area and further increase security.
