Abstract

The process serves for the actuation of <a> electronically locked closure mechanisms of a closure system with the aid of <b> identification means. Each closure mechanism exhibits a microcomputer for communication with the identification means. Each identification means exhibits an identification number, which gives authorisation for the actuation of at least one of the <a> closure mechanisms, and at least one random number. If the microcomputer in the closure mechanism recognises the identification means, via the identification number thereof, as being authorised, it compares the random number of said identification means with the random number which has been stored in it for said identification number. It is only when the two random numbers also correspond that the microcomputer releases the closure mechanism. At the same time, it generates a new random number, which is stored in its closure mechanism and in the identification means.

Description

Die Erfindung betrifft ein Verfahren zum Betätigen von ª elektronisch verriegelten Schließmechanismen eines Schließsystems mit Hilfe von b Identifikationsmitteln, von denen jedes eine Identifikationsnummer aufweist, die zum Betätigen mindestens eines der ª Schließmechanismen berechtigt, bei dem jeder Schließmechanismus einen Mikrocomputer für die Kommunikation mit dem Identifikationsmittel sowie gegebenenfalls mit einer Zentrale aufweist.The invention relates to a method for actuating ª electronically locked locking mechanisms of a locking system with the aid of b identification means, each of which has an identification number that authorizes the actuation of at least one of the ª locking mechanisms, in which each locking mechanism has a microcomputer for communication with the identification means and optionally with a control center.

Verfahren der genannten Art sind bekannt (vgl. z. B. Prospekte "Ihr Schlüssel für die moderne Zeit- und Betriebsdatenerfassung" der Anmelderin, "Der multi­ funktionale Datenschlüssel" von Benzing Zeitwirtschaft AG., "Anwendungsspezifische Mikroelektronische Systeme" des Fraunhofer-Institut) . Dabei ist das Identifikations­ mittel in der Regel ein elektronischer Schlüssel, in dem Daten gespeichert sind, die beim Einstecken in den Steuerteil eines Schlosses von dessen Mikrocomputer gelesen und mit in dem Mikrocomputer gespeicherten Daten verglichen werden. Der Mikrocomputer stellt fest, ob dieser, nämlich einer von b Schlüsseln, z. B. der Schlüssel bx, dieses bestimmte, nämlich eines der ª Schlösser, z. B. das Schloß ax, betätigen darf. Ist der Schlüssel berechtigt, öffnet sich das Schloß; der zugehörige Automat kann bedient, das Arbeiten an dem zugehörigen Gerät ermöglicht, oder eine Tür, die den Zugang zu bestimmten Räumen besonders sichert, freigegeben werden.Methods of the type mentioned are known (cf., for example, brochures "Your key to modern time and operating data acquisition" by the applicant, "The multifunctional data key" by Benzing Zeitwirtschaft AG., "Application-specific microelectronic systems" by the Fraunhofer Institute) . The identification means is usually an electronic key, in which data is stored, which is read when inserted into the control part of a lock by its microcomputer and compared with data stored in the microcomputer. The microcomputer determines whether this, namely one of b keys, e.g. B. the key b x , this particular one, namely one of the ª locks, z. B. may operate the lock a x . If the key is authorized, the lock opens; the associated machine can be operated, work can be carried out on the associated device, or a door that ensures access to certain rooms is particularly secure.

Der Erfindung liegt die Aufgabe zugrunde, das Verfahren der eingangs genannten Art sicherer zu machen, also unbefugte Betätigung des Schließmechanismus zusätzlich zu der bereits in den bekannten Systemen immanenten elektronischen Sicherung in Richtung der Unmöglichkeit der Betätigung durch Unbefugte weiter zu verbessern. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß jedes Identifikationsmittel zusätzlich mindestens einen Speicherplatz zur Aufnahme einer Zufallszahl aufweist, die der Mikrocomputer in dem Schließmechanismus bei Erkennung des Identifikationsmittels über die Identifikationsnummer liest und diese mit der in ihm gespeicherten Zufallszahl für diese Identifikationsnummer vergleicht, daß der Mikrocomputer erst bei Übereinstimmung auch beider Zufallszahlen den Schließmechanismus freigibt und daß er gleichzeitig eine neue Zufallszahl generiert, die im eigenen Schließmechanismus und in dem Identifikations­ mittel gespeichert wird. The object of the invention is the method of the type mentioned at the beginning to make it safer unauthorized actuation of the locking mechanism in addition to that already inherent in the known systems electronic security towards the impossibility to further improve the operation by unauthorized persons. According to the invention, this object is achieved in that that each means of identification additionally at least a memory location for holding a random number which the microcomputer in the locking mechanism upon detection of the means of identification via the Reads identification number and this with the one in it stored random number for this identification number compares that the microcomputer only matches also releases the locking mechanism of both random numbers and that it generates a new random number at the same time, in the own locking mechanism and in the identification medium is saved.  

Bei der Erfindung besteht das Identifikationsmittel im einfachsten Fall aus einem Schlüssel, der eine Leiter­ platte mit aufgelötetem EE-Prom aufweist. Das EE-Prom hat die Eigenschaft, daß man in ihm Daten speichern kann und auch nach Abschalten einer Betriebsspannung die Daten sicher gespeichert sind. Jeder Schließmechanismus besteht aus einem üblichen mechanischen Teil, der elektrisch betätigt wird. Außerdem beinhaltet der Schließmechanismus den Mikrocomputer für die Kommunikation mit dem Identifikationsmittel, gegebenen­ falls mit einer Zentrale, der ebenfalls ein EE-Prom aufweist.In the invention, the identification means consists in simplest case from a key that is a ladder has plate with soldered EE-Prom. The EE Prom has the property that data can be stored in it and even after switching off an operating voltage Data is stored securely. Any locking mechanism consists of a common mechanical part, the is operated electrically. In addition, the Locking mechanism for the microcomputer Communication with the means of identification, given if with a center that also has an EE-Prom having.

Jedes Identifikationsmittel beinhaltet zunächst die Identifikationsnummer, die aussagt, ob ein bestimmtes von b Identifikationsmitteln für einen ganz bestimmten von ª elektronisch verriegelten Schließmechanismen schließ­ berechtigt ist, z. B. das Identifikationsmittel bx für den Schließmechanismus ax. Die Identifikationsnummer kann z. B. eine Personalnummer sein.Each identification means first contains the identification number, which indicates whether a particular one of b identification means is authorized to lock a very specific locking mechanism electronically locked by ª, e.g. B. the identification means b x for the locking mechanism a x . The identification number can e.g. B. be a personnel number.

Gemäß der Erfindung beinhaltet jedes Identifikations­ mittel des Schließsystems zusätzlich mindestens einen Speicherplatz für die Aufnahme einer ganz bestimmten aus einer Vielzahl von Zufallszahlen, die ein Mikro­ prozessor im Schließmechanismus ebenfalls liest. Der Mikroprozessor vergleicht die zu der Identifikationsnummer des eingesteckten bestimmten von b Identifikationsmitteln in ihm gespeicherte Zufallszahl. Bei Übereinstimmung beider Zufallszahlen gibt der Mikroprozessor den Schließmechanismus frei. According to the invention, each identification means of the locking system additionally contains at least one storage space for the inclusion of a very specific one of a large number of random numbers, which a microprocessor in the locking mechanism also reads. The microprocessor compares the random number stored in it to the identification number of the specific one of b identification means inserted in it. If both random numbers match, the microprocessor releases the locking mechanism.

Gleichzeitig wird von dem Mikroprozessor des Schließ­ mechanismus eine neue Zufallszahl generiert und einerseits in dem Identifikationsmittel anstelle der bisherigen Zufallszahl gespeichert, andererseits in dem Mikro­ prozessor des Schließmechanismus. Mit anderen Worten: Das Identifikationsmittel, z. B. der Schlüssel, bekommt bei jeder Betätigung des Schließmechanismus, z. B. des Schlosses, eine neue Kennung, die ihm beim nächsten Gebrauch Zugangsberechtigung zu dem Schließmechanismus verschafft.At the same time, the closing microprocessor mechanism generates a new random number and on the one hand in the means of identification instead of the previous one Random number stored on the other hand in the micro processor of the locking mechanism. In other words: The identification means, e.g. B. the key with each actuation of the locking mechanism, e.g. B. of Lock, a new identifier that will be given to the next Use access authorization to the locking mechanism procured.

Sollte das Identifikationsmittel von einem Unberechtigten kopiert werden, so ist die Kopie des Identifikations­ mittels nur so lange zu gebrauchen, wie das Original- Identifikationsmittel nicht von dem Berechtigten benutzt wird. Wird nämlich das Original-Identifikationsmittel nach der Benutzung der Kopie des Identifikationsmittels benutzt, hat das Original-Identifikationsmittel keinen Zugang mehr, da es noch die "alte", nicht die inzwischen generierte Zufallszahl trägt; die Betätigung durch den Unberechtigten ist festgestellt. Weitere Betätigung durch ihn wird gesperrt.If the means of identification is from an unauthorized person are copied, so is the copy of the identification by using only as long as the original Identification means not used by the authorized person becomes. It becomes the original means of identification after using the copy of the means of identification used, the original means of identification has none Access more since it's still the "old" one, not the one meanwhile generated random number carries; the actuation by the Unauthorized persons are identified. Further actuation by he will be blocked.

Bei Herstellung eines Neu-Identifikationsmittels setzt eine Zentrale in dem Schließmechanismus für den einzelnen Berechtigten den Speicherplatz der Zufallszahl auf "Null". Bei der Erstbetätigung des Neu-Identifikationsmittels im Schließmechanismus stimmen dann wieder alle Rand­ bedingungen und das Schloß generiert - wie beschrieben - eine Zufallszahl und speichert diese intern und in dem Identifikationsmittel. When producing a new means of identification a center in the locking mechanism for the individual Authorized the storage space of the random number to "zero". When the new identification means is activated for the first time in the locking mechanism all edges are correct again conditions and the lock generates - as described - a random number and stores it internally and in the Means of identification.  

Handelt es sich bei dem Schlüssel um einen "Universal­ schlüssel", der innerhalb eines Schließsystems eine Reihe von Schlössern betätigen darf, sind entweder mehrere Speicherplätze zur Aufnahme mehrerer Zufalls­ zahlen vorzusehen oder jeder Schließmechanismus des Schließsystems ist mit einer Zentrale verbunden, die die jeweils zuletzt generierte Zufallszahl für die Schließmechanismen eines Schließsystems zentral speichert.If the key is a "universal key ", the one within a locking system Row of locks are either multiple memory locations to record multiple random pay to provide or any locking mechanism of the Locking system is connected to a control center that the last generated random number for the Central locking mechanisms of a locking system saves.
