Definitions

  • the invention relates to a system with an electronic lock, which is convertible by entering a currently valid, unique release code from its locked state to its release state, and an electronic device arranged separately from the lock.
  • Electronic locks are arranged, for example, for locking the closed position of closing elements on lockers, lockers, mailboxes or rooms.
  • a release code in the electronic lock this can be transferred from its locking position locking the locking state in its release state by the closure member is moved by manual operation in one of its open positions.
  • Such a release code can be formed for example by a sequence of numbers.
  • the US 2011/0041573 A1 describes a system with an electronic lock, which is convertible by entering a currently valid, unique release code from its locked state to its release state, and an electronic device arranged separately from the lock, wherein the electronic lock and the electronic device are adapted to the currently valid, one-time release code.
  • the object of the invention is to provide a system for generating a currently valid, unique release code for an electronic lock, through which an electronic lock can be created with maximum security against unauthorized operation.
  • the currently valid, unique release code by encryption of the immediately preceding valid, one-time Release code is generated by means of an encryption algorithm, wherein the encryption takes place in consideration of an encryption key, wherein the electronic lock and the electronic device are adapted to the encryption key from an input, individual master code and stored in the electronics of the lock and in software of the electronic Device to generate key code generated.
  • the currently valid, one-time release code is generated both by the electronics of the lock, as well as by the electronic device, wherein the same encryption of immediately preceding valid, unique release code is done. For the user of the system, it is possible to obtain knowledge of the currently valid, unique release code via the separately arranged electronic device in order to be able to subsequently enter this in the electronic lock.
  • an encryption algorithm for generating currently valid, one-time release codes represents a very atypical use of an encryption algorithm, in particular since it is not a question of making accessible information accessible only to certain persons.
  • an unauthorized person can not know which type of encryption algorithm is used, so that even with knowledge of an initial, currently valid, one-time release code, it can not be inferred what the subsequently generated, valid, one-time release code is.
  • an inventive system is characterized by a high degree of security.
  • the encryption key is generated from an input, individual master code and a key code stored in the electronics of the lock.
  • electronic lock which knows the key code stored in the electronics of the lock, by the taking place by entering the individual master codes customization of future, unique release codes no statement about a currently valid or meet future, one-time release code.
  • This embodiment thus serves to provide an electronic lock with maximum security against unauthorized operation of the same.
  • the first currently valid after activation of the electronic lock, unique release code is determined taking into account an input, individual start code as immediately previously valid, one-time release code. This also achieves the greatest possible individualization of future, one-off release codes.
  • This embodiment also offers the possibility of being able to reset the electronic lock to a defined initial state, if the currently valid, one-time release code is no longer known. In such a case, the user of the lock again enters an individual start code and then an individual master code in the electronic lock. From this, the next currently valid, one-time release code is generated.
  • the electronic lock can be signaled whether the code entered should be a start or a master code.
  • the encryption algorithm used is AES (Advanced Encryption Standard), DES (Data Encryption Standard), Triple-DES, Blowfish, RC4 (Ron's Code 4), RC5 or RC6.
  • AES Advanced Encryption Standard
  • DES Data Encryption Standard
  • Triple-DES Triple-DES
  • Blowfish Blowfish
  • RC4 Ron's Code 4
  • RC5 or RC6 RC6
  • the currently valid, unique release code is generated both by the electronics of the lock, as well as by a program running on the electronic device and by this electronic device displayed, wherein by means of the program the same encryption of immediately preceding valid, unique release code is done, as in the electronics of the castle.
  • the currently valid, one-time release code it becomes possible for the user of the system according to the invention to obtain knowledge of the currently valid, one-time release code in order to then be able to enter it into the electronic lock.
  • an electronic device is both a mobile, as well as a stationary electronic device into consideration. Examples of mobile devices are conventional mobile terminals, laptops or the like.
  • a stationary device for example, a PC application.
  • FIG. 1 schematically shows the method for generating a currently valid, unique release code 1.
  • This currently valid, unique release code 1 first an individual master code 2 entered into the lock and a key code 3 stored in the lock's electronics are used to generate an encryption code 4 to generate.
  • This encryption key 4 is taken into account in the encryption of the immediately preceding, one-time release code 5 by means of the encryption algorithm 6.
  • FIG. 2 schematically shows an embodiment of the system 7 according to the invention with an arranged on a closing element 8 of a closing unit not shown, electronic lock 9 and one of the lock 9 separately arranged electronic device 10 in the form of a personal computer.
  • To start up the electronic lock 9 is first an individual start code from the user of the electronic lock 9 as immediately prior valid, one-time release code entered into the electronic lock 9. The user then enters an individual master code in the lock. As in FIG. 1 is shown, the currently valid, unique release code is generated from these entered codes, with which the electronic lock 9 can be converted from its locked state to its release state.
  • the user of the electronic lock 9 is equipped by the manufacturer of the lock 9 with software which is installed on the electronic device 10. This software includes the same encryption algorithm as stored in the electronics of the lock 9.
  • the software includes the same key code as it is also stored in the electronics of the lock 9. If the user inputs the same individual start code and the same individual master code as he has already entered into the electronic lock 9 after the lock 9 has been put into the electronic device 10, the software running on the electronic device 10 generates the same current valid one-time release code, as it has been generated by the electronic lock 9. On the display 11 on the electronic device 10, the user can read the currently valid, unique release code and enter for transferring the electronic lock from its locking state in its release state in the electronic lock 9.
