Description

Die Erfindung betrifft ein System mit einem elektronischen Schloss, welches durch Eingabe eines aktuell gültigen, einmaligen Freigabecodes von seinem Verriegelungszustand in seinen Freigabezustand überführbar ist, und einer von dem Schloss separat angeordneten, elektronischen Einrichtung.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.

Elektronische Schlösser werden beispielsweise zum Verriegeln der Schließstellung von Schließelementen an Spinden, Schließfächern, Postfächern oder Räumen angeordnet. Durch Eingabe eines Freigabecodes in das elektronische Schloss lässt sich dieses von seinem die Schließstellung verriegelnden Verriegelungszustand in seinen Freigabezustand überführen, indem das Schließelement durch manuelle Betätigung in eine seiner Offenstellungen bewegbar ist. Ein solcher Freigabecode kann beispielsweise durch eine Zahlenfolge gebildet sein.Electronic locks are arranged, for example, for locking the closed position of closing elements on lockers, lockers, mailboxes or rooms. By entering 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.

Um die Sicherheit solcher elektronischer Schlösser beziehungsweise damit ausgestatteter Einrichtungen gegen unbefugte Betätigung zu erhöhen, ist es bekannt, einmalige Freigabecodes zu verwenden, durch deren Eingabe in das Schloss dieses lediglich einmal von seinem Verriegelungszustand in seinen Freigabezustand überführbar ist. Zur nachfolgenden Überführung dieses elektronischen Schlosses von seinem Verriegelungszustand in seinen Freigabezustand ist die Eingabe eines neuen aktuell gültigen, einmaligen Freigabecodes erforderlich.In order to increase the security of such electronic locks or devices equipped therewith against unauthorized operation, it is known to use unique release codes, by their entry into the castle this is only once from its locked state in its release state can be transferred. For the subsequent transfer of this electronic lock from its locking state in its release state, the entry of a new currently valid, unique release code is required.

Aus der EP 0 767 286 A2 ist ein System mit einem elektronischen Schloss bekannt, welches durch Verwendung eines elektronischen Schlüssels mit einem aktuell gültigen, einmaligen Freigabecode von seinem Verriegelungszustand in seinen Freigabezustand überführbar ist, und einer von dem Schlüssel separat angeordneten, elektronischen Einrichtung. Mittels Kommunikation zwischen dem Schlüssel und der separat angeordneten, elektronischen Einrichtung werden Informationen, wie neue Freigabecodes und Verschlüsselungscodes, von der separat angeordneten elektronischen Einrichtung auf den elektronischen Schlüssel übertragen. Die Kommunikation zwischen dem Schlüssel und der separat angeordneten elektronischen Einrichtung macht das elektronische Schloss angreifbar.From the EP 0 767 286 A2 a system is known with an electronic lock, which is convertible by using an electronic key with a currently valid, unique release code from its locked state to its release state, and an electronic device arranged separately from the key. By means of communication between the key and the separately arranged electronic device, information such as new release codes and encryption codes are transmitted from the separately arranged electronic device to the electronic key. The communication between the key and the separate electronic device makes the electronic lock vulnerable.

Die US 2011/0041573 A1 beschreibt ein System mit einem elektronischen Schloss, welches durch Eingabe eines aktuell gültigen, einmaligen Freigabecodes von seinem Verriegelungszustand in seinen Freigabezustand überführbar ist, und einer von dem Schloss separat angeordneten, elektronischen Einrichtung, wobei das elektronische Schloss und die elektronische Einrichtung dazu eingerichtet sind, den aktuell gültigen, einmaligen Freigabecode zu erzeugen. Dadurch, dass keine direkte Kommunikation zwischen dem Schloss und der separaten elektronischen Einrichtung erforderlich ist, ist das System über diesen Weg nicht angreifbar. Allerdings kann bei Kenntnis der Verschlüsselung auf die zukünftigen einmaligen Freigabecodes geschlossen werden. Insbesondere seitens des Schlossherstellers oder auch des Schlosseigentümers kann unbefugte Betätigung durch aktuelle oder ehemalige Mitarbeiter oder beauftragte Dienstleister, die Kenntnis von der Verschlüsselung erlangt haben, nicht ausgeschlossen werden.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. By not requiring direct communication between the lock and the separate electronic device, the system is not vulnerable to this path. However, with knowledge of the encryption on the future one-off release codes can be concluded. Unauthorized operation by current or former employees or contracted service providers who have gained knowledge of the encryption can not be ruled out, in particular by the lock manufacturer or the lock owner.

Aufgabe der Erfindung ist es, ein System zum Erzeugen eines aktuell gültigen, einmaligen Freigabecodes für ein elektronisches Schloss bereitzustellen, durch das ein elektronisches Schloss mit höchster Sicherheit gegen unbefugte Betätigung geschaffen werden kann.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.

Diese Aufgabe wird durch ein System der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass der aktuell gültige, einmalige Freigabecode durch eine Verschlüsselung des unmittelbar vorhergehend gültigen, einmaligen Freigabecodes mittels eines Verschlüsselungsalgorithmus erzeugt wird, wobei die Verschlüsselung unter Berücksichtigung eines Verschlüsselungscodes erfolgt, wobei das elektronische Schloss und die elektronische Einrichtung dazu eingerichtet sind, den Verschlüsselungscode aus einem eingegebenen, individuellen Mastercode und einem in der Elektronik des Schlosses abgelegten und in einer Software der elektronischen Einrichtung umfassten Schlüsselcode zu generieren. Der aktuell gültige, einmalige Freigabecode wird sowohl von der Elektronik des Schlosses, als auch von der elektronischen Einrichtung erzeugt, wobei dieselbe Verschlüsselung des unmittelbar vorhergehend gültigen, einmaligen Freigabecodes erfolgt. Für den Nutzer des Systems ist es möglich, über die separat angeordnete elektronische Einrichtung Kenntnis von dem aktuell gültigen, einmaligen Freigabecode zu erhalten, um diesen anschließend in das elektronische Schloss eingeben zu können. Hierdurch ist keine Kommunikation zwischen dem Schloss und der separat angeordneten elektronische Einrichtung nötig, die das Schloss angreifbar für Hacker machen würde. Dennoch ist es für den Nutzer möglich, den aktuell gültigen, einmaligen Freigabecode des Schlosses anhand der separat angeordneten, elektronischen Einrichtung zu erhalten.This object is achieved by a system of the type mentioned in the present invention that 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. As a result, no communication between the lock and the separately arranged electronic device is necessary, which would make the lock vulnerable to hackers. Nevertheless, it is possible for the user to obtain the currently valid, one-time release code of the lock on the basis of the separately arranged, electronic device.

Der erfindungsgemäße Einsatz eines Verschlüsselungsalgorithmus zum Erzeugen von aktuell gültigen, einmaligen Freigabecodes stellt eine sehr untypische Verwendung eines Verschlüsselungsalgorithmus dar, insbesondere da es nicht darum geht, eine für jeden zugängliche Information nur für bestimmte Personen zugänglich zu machen. Zudem kann eine unbefugte Person nicht wissen, welche Art von Verschlüsselungsalgorithmus verwendet wird, so dass selbst bei Kenntnis eines anfänglichen, aktuell gültigen, einmaligen Freigabecodes nicht darauf zurück geschlossen werden kann, wie der nachfolgend erzeugte aktuell gültige, einmalige Freigabecode lautet. Somit zeichnet sich ein erfindungsgemäßes System durch ein hohes Maß an Sicherheit aus.The use according to the invention of 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. In addition, 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. Thus, an inventive system is characterized by a high degree of security.

Erfindungsgemäß wird der Verschlüsselungscode aus einem eingegebenen, individuellen Mastercode und einem in der Elektronik des Schlosses abgelegten Schlüsselcode generiert. Dies ermöglicht es einem Nutzer eines elektronischen Schlosses, durch wiederholtes Eingeben von individuellen Mastercodes die zukünftigen, einmaligen Freigabecodes individuell generieren zu lassen. Für Dritte wird es unmöglich, Kenntnis von dem aktuell gültigen, einmaligen Freigabecode zu erlangen, so dass keine unbefugte Betätigung eines gemäß dieser Ausgestaltung des erfindungsgemäß betriebenen, elektronischen Schlosses erfolgen kann. Zudem kann selbst der Hersteller eines nach dieser Ausgestaltung des erfindungsgemäßen Verfahrens betriebenen, elektronischen Schlosses, welcher den in der Elektronik des Schlosses abgelegten Schlüsselcode kennt, durch die durch die Eingabe der individuellen Mastercodes erfolgende Individualisierung der zukünftigen, einmaligen Freigabecodes keine Aussage über einen aktuell gültigen oder zukünftigen, einmaligen Freigabecode treffen. Diese Ausgestaltung dient somit der Schaffung eines elektronischen Schlosses mit maximaler Sicherheit gegen unbefugte Betätigung desselben.According to the invention, the encryption key is generated from an input, individual master code and a key code stored in the electronics of the lock. This allows a user of an electronic lock to individually generate future unique release codes by repeatedly entering individual master codes. For third, it becomes impossible to know of the currently valid, one-off To obtain release code, so that no unauthorized operation of an according to this embodiment of the invention operated, electronic lock can be done. In addition, even the manufacturer of operated according to this embodiment of the method, 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.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung wird der nach Inbetriebnahme des elektronischen Schlosses erste aktuell gültige, einmalige Freigabecode unter Berücksichtigung eines eingegebenen, individuellen Startcodes als unmittelbar vorhergehend gültiger, einmaliger Freigabecode ermittelt. Auch hierdurch wird eine weitestgehende Individualisierung der zukünftigen, einmaligen Freigabecodes erreicht. Diese Ausgestaltung bietet zudem die Möglichkeit, das elektronische Schloss auf einen definierten Ausgangszustand zurücksetzen zu können, falls der aktuell gültige, einmalige Freigabecode nicht mehr bekannt ist. In einem solchen Fall gibt der Nutzer des Schlosses erneut einen individuellen Startcode und anschließend einen individuellen Mastercode in das elektronische Schloss ein. Hieraus wird der nächste aktuell gültige, einmalige Freigabecode erzeugt. Vorzugsweise kann dem elektronischen Schloss signalisiert werden, ob der eingegebene Code ein Start- oder ein Mastercode sein soll.According to a further advantageous embodiment of the invention, 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. Preferably, the electronic lock can be signaled whether the code entered should be a start or a master code.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung wird als Verschlüsselungsalgorithmus AES (Advanced Encryption Standard), DES (Data Encryption Standard), Triple-DES, Blowfish, RC4 (Ron's Code 4), RC5 oder RC6 verwendet. Diese Verschlüsselungsalgorithmen zeichnen sich durch ein hohes Maß an Sicherheit aus.According to a further advantageous embodiment of the invention, the encryption algorithm used is AES (Advanced Encryption Standard), DES (Data Encryption Standard), Triple-DES, Blowfish, RC4 (Ron's Code 4), RC5 or RC6. These encryption algorithms are characterized by a high degree of security.

Vorzugsweise wird der aktuell gültige, einmalige Freigabecode sowohl von der Elektronik des Schlosses, als auch von einem auf der elektronischen Einrichtung ablaufenden Programm erzeugt und von dieser elektronischen Einrichtung angezeigt, wobei mittels des Programms dieselbe Verschlüsselung des unmittelbar vorhergehend gültigen, einmaligen Freigabecodes erfolgt, wie in der Elektronik des Schlosses. Durch das Anzeigen des aktuell gültigen, einmaligen Freigabecodes wird es dem Nutzer des erfindungsgemäßen Systems möglich, Kenntnis von dem aktuell gültigen, einmaligen Freigabecode zu erhalten, um diesen anschließend in das elektronische Schloss eingeben zu können. Als elektronische Einrichtung kommt sowohl eine mobile, als auch eine stationäre elektronische Einrichtung in Betracht. Beispiele für mobile Einrichtungen sind herkömmliche Mobilfunkendgeräte, Laptops oder dergleichen. Als stationäres Gerät findet beispielsweise ein PC Anwendung.Preferably, 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. By displaying 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. As 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. As a stationary device, for example, a PC application.

FIG. 2:
a schematic representation of an embodiment of the system according to the invention.

Figur 1 zeigt schematisch das Verfahren zum Erzeugen eines aktuell gültigen, einmaligen Freigabecodes 1. Zur Erzeugung dieses aktuell gültigen, einmaligen Freigabecodes 1 werden zunächst ein in das Schloss eingegebener, individueller Mastercode 2 und ein in der Elektronik des Schlosses abgelegter Schlüsselcode 3 verwendet, um einen Verschlüsselungscode 4 zu generieren. Dieser Verschlüsselungscode 4 wird bei der Verschlüsselung des unmittelbar vorhergehend gültigen, einmaligen Freigabecodes 5 mittels des Verschlüsselungsalgorithmus 6 berücksichtigt. FIG. 1 schematically shows the method for generating a currently valid, unique release code 1. To generate 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.

Figur 2 zeigt schematisch ein Ausführungsbeispiel für das erfindungsgemäße System 7 mit einem an einem Schließelement 8 einer nicht näher dargestellten Schließeinheit angeordneten, elektronischen Schloss 9 und einer von dem Schloss 9 separat angeordneten, elektronischen Einrichtung 10 in Form eines PCs. Zur Inbetriebnahme des elektronischen Schlosses 9 wird zunächst ein individueller Startcode von dem Nutzer des elektronischen Schlosses 9 als unmittelbar vorhergehend gültiger, einmaliger Freigabecode in das elektronische Schloss 9 eingegeben. Anschließend gibt der Nutzer einen individuellen Mastercode in das Schloss ein. Wie in Figur 1 gezeigt, wird aus diesen eingegebenen Codes der aktuell gültige, einmalige Freigabecode erzeugt, mit dem das elektronische Schloss 9 von seinem Verriegelungszustand in seinen Freigabezustand überführbar ist. Der Nutzer des elektronischen Schlosses 9 wird vom Hersteller des Schlosses 9 mit einer Software ausgestattet, welche auf der elektronischen Einrichtung 10 installiert ist. Diese Software umfasst denselben Verschlüsselungsalgorithmus, wie er in der Elektronik des Schlosses 9 abgelegt ist. Zudem umfasst die Software denselben Schlüsselcode, wie er ebenfalls in der Elektronik des Schlosses 9 abgelegt ist. Gibt der Nutzer nach Inbetriebnahme des Schlosses 9 in die elektronische Einrichtung 10 denselben individuellen Startcode und denselben individuellen Mastercode ein, wie er sie bereits in das elektronische Schloss 9 eingegeben hat, erzeugt die auf der elektronischen Einrichtung 10 ablaufende Software denselben aktuell gültigen, einmaligen Freigabecode, wie er von dem elektronischen Schloss 9 erzeugt worden ist. Über die Anzeige 11 an der elektronischen Einrichtung 10 kann der Nutzer den aktuell gültigen, einmaligen Freigabecode ablesen und zum Überführen des elektronischen Schlosses von seinem Verriegelungszustand in seinen Freigabezustand in das elektronische Schloss 9 eingeben. 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. In addition, 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.
