Data security device for systems that process energy and water meter readings, so-called smart metering systems, characterized in that - the count of a media counter 3 or alternatively the code of a special code counter, which is integrated as a subscriber in the counter bus system, regardless of smart meter Metering system 1 is read and provided to the user terminal 2, - an access request of the user terminal 2 to the smart metering system 1 with the count of the media counter 3 or with the code of the code counter is made, - this counter also by the smart metering System 1 is read out via the internal counter bus systems, - a comparison of the two meter readings takes place and - if the access permission for the user terminal 2 is granted in the case of coincidence.
Description
Mit der EU-Richtlinie EDL 2006/32/EG und dem Energiewirtschaftsgesetz ENWG §21d zum Smart Metering sollen intelligente Zähleinrichtungen dem Nutzer den tatsächlichen Energieverbrauch im Zusammenhang mit der tatsächlichen Nutzungszeit verfügbar machen. Ähnlich der Kraftstoffverbrauchsanzeige von PKW wird der Gebäudenutzer aus wirtschaftlichen- und Umweltschutzerwägungen bemüht sein, seinen Verbrauch möglichst gering zu halten.With the EU Directive EDL 2006/32 / EC and the Energy Industry Act ENG §21d on Smart Metering, intelligent counting devices should make the actual energy consumption available to the user in connection with the actual usage time. Similar to the fuel consumption display of passenger cars, the building user will endeavor to keep his consumption as low as possible for economic and environmental reasons.
Dadurch, dass viele moderne Zähler diverse Datenschnittstellen und Datenfernübertragungseinrichtungen besitzen, besteht die Gefahr des gläsernen Kunden. Über das Verbrauchsverhalten von Strom, Brennstoff, Wärme und Wasser, das in engem Zeittakt abgefragt werden kann, lassen sich perfekte Persönlichkeitsprofile erstellen. Der Abnehmer kann gar nicht mehr kontrollieren, welche Zählerdaten wem und wann zur Verfügung gestellt werden. Es erscheint technisch wesentlich sinnvoller, Zählerdaten auf einer geschützten Ebene bspw. dem M-Bus zu einem Smart-Metering-System zu übertragen und erst dort die dem Nutzer obliegenden Zugriffsrechte festzulegen.The fact that many modern meters have various data interfaces and remote data transmission equipment, there is a risk of the glass customer. About the consumption behavior of electricity, fuel, heat and water, which can be queried in a tight time, perfect personality profiles can be created. The customer can no longer control which meter data are provided to whom and when. It seems technically much more useful to transmit meter data on a protected level, for example, the M-bus to a smart metering system and only there determine the access rights incumbent on the user.
Die Bestrebungen des Gesetzgebers sind darauf gerichtet, dass der Nutzer sein Verbrauchsverhalten so wählt, dass eine Energie- und damit CO2-Einsparung eintritt und er lastabhängige und damit seiner Nutzerspezifik angepasste Tarife nutzen kann. Die Hoheit über die Verwendung dieser persönlichen Zählerdaten muss jedoch unbedingt beim Nutzer bleiben.The aim of the legislator is that the user chooses his consumption behavior so that an energy and thus CO 2 savings occurs and he can use load-dependent and thus adapted to his user specifications tariffs. However, the sovereignty over the use of personal meter data must remain with the user.
Bestehende Systeme verwenden zur Datensicherheit, Passwörter, MAC-Adressen, VPN-Verbindungen und vieles andere mehr. Diesen Systemen haftet die Schwierigkeit an, dass unberechtigte Nutzer nach illegalem oder versehentlichem Erhalt der Software-Schlüssel auf die Nutzerdaten zugreifen können.Existing systems use data security, passwords, MAC addresses, VPN connections, and more. These systems are subject to the difficulty that unauthorized users can access the user data after illegally or accidentally receiving the software keys.

Die erfindungsgemäße Datensicherheitsvorrichtung gemäß
Die Datensicherheitsvorrichtung ist für Systeme geeignet, die Energie- und Wasserzählerstände weiterverarbeiten, die sogenannten Smart-Metering-Systeme. Die Datensicherheitsvorrichtung ist dadurch gekennzeichnet, dass zuerst der Zählerstand eines Medienzählers
Beide mit unterschiedlichen Verfahren ermittelten Zählerstände werden verglichen und bei Übereinstimmung wird die Zugriffserlaubnis für das Nutzerendgerät
Eine weitere erfindungsgemäße Ausbildung der Datensicherheitsvorrichtung besteht darin, dass anstelle des Medienzählers
Außerdem lassen sich für die Zugriffskontrolle nicht nur ein Medien- oder Codezählerstand nutzen, sondern auch mehrere Zählerstände oder Zählerstandkombinationen.In addition, not only a media or code counter reading can be used for access control, but also multiple meter readings or meter reading combinations.
Eine weitere spezielle Datensicherheitsvorrichtung nutzt für das Ablesen des Zählerstandes des Medien- oder Codezählers
Die Datensicherheitsvorrichtung kann nach dem Verbindungsaufbau zwischen dem Smart-Metering-System 1 und dem Nutzerendgerät
Falls der Nutzer nicht zu Hause ist und sein Smart-Metering-System
