Definitions

  • the present invention relates to a high security electronic key-lock system with wireless remote control, actuating opening and closing relays comprising a transmitting key and a receiving lock.
  • Patent application WO-A-85 01980 concerning an optical transmission key and a lock capable of accepting several codes from the key also has the drawback of interceptable and reusable codes: in fact, the lock checks only if the code received is well saved in his memory.
  • the installation according to this request FR-A-2 536 781 comprises a resynchronization system which consists in simultaneously transmitting to the code a signal allowing the lock in the event of a mismatch between the code received and the code which had to be received, to consider one of the following codes in the succession and to compare it with the code received.
  • Another resynchronization system exposed in the cited request consists in sending an auxiliary code allowing a reinitialization in the succession of codes of the key and of the lock.
  • desynchronizations are frequent and the locks will be set to accept codes already issued.
  • this system does not prevent desynchronizations, each of them requiring manual intervention detrimental to the comfort of use and safety.
  • EP-A-0 432 270 is presented a card unlocking system.
  • This system does not present the risk of interception between a key and a lock and therefore does not include means avoiding this risk, the card serving as a key always containing the same information. It would therefore not be safe to implement this operating principle in a remote control system because the information could be very easily intercepted and reproduced to actuate the lock.
  • the present invention eliminates the above-mentioned drawbacks by proposing a wireless remote control key-lock system, in which the key is transmitting and transmits unpredictable and different codes during each transmission and in which the lock is receiving and identifies the transmitting key from the variable codes received, accepts these codes if they come from an authorized key and permanently eliminates any code already accepted.
  • the data sent by the key that is to say, Y, X, TXY and TCXSY, and interceptable, are not secret. TXY and TCXSY change during each transmission and TCXSY is unpredictable because the algorithm which generates it is secret.
  • the comparator authorizes, depending on the signal (+) or (-) received from the key, the closing or opening of a relay 1.
  • This comparator increments, via a connection C ′, the value TYX, recorded in the memory A ′ of the lock in correspondence of the key considered, at the level of the value TXY received from the key.
  • the key-lock system thus described is an analog representation of an electronic component which can group together all the memory, comparator and calculator functions.
  • the proposed invention ensures the inviolability of the key-lock system with remote control and transmitter key and receiver lock because the combination issued is variable with each transmission, is unpredictable and is ineffective if it is reproduced after interception.
