Verfahren zur Adresszuordnung und Datenverarbeitungssystem zur Durchführung des VerfahrensAddress allocation method and data processing system for carrying out the method
Die Erfindung betrifft ein Verfahren zur Adresszuordnung für eine Hardware- und Software aufweisende Komponente eines Datenverarbeitungssystems sowie ein Datenverarbeitungssystem zur Durchführung des Verfahrens.The invention relates to a method for address assignment for a hardware and software having component of a data processing system and a data processing system for performing the method.
Die Adressen der, insbesondere als Rechner fungierenden, Komponenten eines Datenverarbeitungssystems sind bei bekannten Systemen prinzipiell der auf der Komponente ablaufenden Software zugeordnet. Üblicherweise wird bei der Installation der Software auf der Komponente eine komponentenspezifischeThe addresses of the, in particular functioning as a computer, components of a data processing system are in principle associated with the software running on the component in known systems. Typically, installing the software on the component becomes component-specific
TCP/IP (Transmission Control Protocol/Internet Protocol)- Adresse mit SUBNET-Maske festgelegt oder per DHCP (Dynamic Host Configuration Protocol) dynamisch bei der Aktivierung der TCP/IP-Datenaustausch-Software vergeben. Problematisch bei der Software-Adressierung ist vor allem die Veränderbarkeit oder Löschbarkeit der Adresse durch beabsichtigte oder unbeabsichtigte Eingriffe in die Software.Transmission Control Protocol / Internet Protocol (TCP / IP) - Specifies the address using the SUBNET mask or dynamically assigns it by DHCP (Dynamic Host Configuration Protocol) when the TCP / IP communication software is activated. The main problem with software addressing is the changeability or erasability of the address due to intentional or unintentional interference with the software.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und ein Verfahren sowie ein Datenverarbeitungssystem anzugeben, welche eine Adressmanipulation ausschließen oder erheblich erschweren.The invention has for its object to overcome this drawback and to provide a method and a data processing system, which preclude or considerably complicate address manipulation.
Verfahrensgemäß wird die Aufgabe dadurch gelöst, dass die Adresse der Hardware zugeordnet wird.According to the method, the object is achieved in that the address of the hardware is assigned.
Bei einem zur Durchführung des Verfahrens geeigneten Datenverarbeitungssystem ist die Adresse folglich als Hardwareausprägung ausgebildet. Auf diese Weise kann die Adresse nur durch Eingriffe in die Hardware - nicht aber durch Softwareeingriffe - verändert werden. Vorzugsweise wird die Adresse, insbesondere TCP/IP- Adresse mit Subnet-Masken-Adresse, vor der Lieferung der Komponente des Datenverarbeitungssystems mit dem Kunden vereinbart .In a suitable for performing the method data processing system, the address is thus designed as a hardware expression. In this way, the address can be changed only by intervening in the hardware - but not by software intervention. Preferably, the address, in particular TCP / IP address with subnet mask address, is agreed upon prior to the delivery of the component of the data processing system to the customer.
Dadurch, dass die Adresse der Komponente als Hardwareausprä- gung ausgebildet ist, kann sie als nahezu unverlierbareDue to the fact that the address of the component is designed as a hardware design, it can be regarded as almost captive
Eigenschaft eingestuft werden. Insbesondere bei Datenverarbeitungssystemen mit sicherheitsrelevanter Bedeutung, beispielsweise für Schienenverkehrssysteme, wird die Sicherheits-Nachweisführung für die korrekte Ermittlung des Ziel-Rechners für Datenfernübertragungen aller Art wesentlich vereinfacht, weil die komplexeren Umwege für die Software- Adressierung mittels MAC (Media Access Control) -Adresse, Rechner-ID usw. ganz entfallen. Damit entfällt bei der Sicherheits-Nachweisführung ein erheblicher, bei Software- Adressierung zu beantwortender Fragenkomplex im Fehlerbaum. Letztlich ergeben sich erhebliche Kosteneinsparungen in Verbindung mit vereinfachter Sicherheits-Argumentation und erhöhter Akzeptanz bei Zulassungsbehörden und Systembetreibern.Property to be classified. Particularly in data processing systems with security-relevant significance, for example for rail transport systems, the security evidence for the correct determination of the target computer for remote data transmission of all types is much easier, because the more complex detours for software addressing using the MAC (Media Access Control) address, Calculator ID, etc. completely omitted. This eliminates the need for a significant, in software addressing addressing question complex in the fault tree at the security verification. Ultimately, there are significant cost savings associated with simplified safety reasoning and increased acceptance by regulatory authorities and system operators.
Gemäß Anspruch 3 ist die Adresse als Ausprägung eines RFID (Radio Frequency Identification) -Chip ausgebildet. Dieser Chip wird fest mit der zu adressierenden Komponente verbunden. Die Software für den Datenaustausch mit anderen Komponenten liest die Adresse der Ziel-Komponente von deren RFID- Chip und verwendet nur diese für den Datenaustausch.According to claim 3, the address is formed as a form of RFID (Radio Frequency Identification) chip. This chip is firmly connected to the component to be addressed. The software for exchanging data with other components reads the address of the target component from its RFID chip and only uses it for data exchange.
Gemäß Anspruch 4 besteht die Adresse aus einer TCP/IP-Adresse und einer Subnet-Masken-Adresse. Mittels der IP-Adresse und der Subnet-Maske können Rechner bzw. Komponenten innerhalb eines Netzwerkes in Subnetze gruppiert werden. Auf dieser Basis ist es möglich, Komponenten in größeren Netzwerken zu adressieren und eine Logik für das Routing der Netzwerkpakete oder Netzwerktelegramme aufzubauen. Das Internetprotokoll als Grundlage des Internets unterstützt dabei die eindeutige Identifizierung der anzusprechenden Komponenten.According to claim 4, the address consists of a TCP / IP address and a subnet mask address. By means of the IP address and the subnet mask computer or components within a network can be grouped into subnets. On this basis, it is possible to address components in larger networks and to establish a logic for the routing of the network packets or network telegrams. The Internet protocol as the basis of the Internet supports the clear identification of the components to be addressed.
Die Erfindung wird nachfolgend anhand einer figürlichen Darstellung näher erläutert.The invention will be explained in more detail with reference to a figurative representation.
Die Figur zeigt das Funktionsprinzip der Adressvergabe.The figure shows the functional principle of address assignment.
Ein Datenverarbeitungssystem besteht üblicherweise aus n Rechner-Komponenten 1.1 bis l.n, welche über ein Bussystem 2, beispielsweise WLAN (Wireless Low Area Network) , Ethernet oder Cheapernet miteinander kommunizieren. Dazu sind die Komponenten 1.1 bis l.n mit Datenaustausch-Software 3.1 bis 3.n ausgestattet. Diese Software 3.1 bis 3.n liest eine für den Datenaustausch benötigte TCP/IP-Adresse und eine Subnet-Mas- ken-Adresse von einem Hardware-Bestandteil 4.1 bis 4.n, beispielsweise einem RFID-Chip, des jeweiligen Ziel-Rechners 1.1 bis l.n. Ein Lade-Rechner 5 aktiviert die Ziel-Rechner 1.1 bis l.n derart, dass die Hardware 4.1 bis 4.n für den Zugriff durch die Datenaustausch-Software 3.1 bis 3.n freigegeben wird. Die TCP/IP-Adresse und die Subnet-Masken-Adresse sind nicht Bestandteil der Software 3.1 bis 3.n, sondern der Hardware 4.1 bis 4.n der Rechner-Komponenten 1.1 bis l.n, so dass die Adressierung nicht durch Software-Eingriff veränderbar ist . A data processing system usually consists of n computer components 1.1 to 1.n which communicate with one another via a bus system 2, for example WLAN (Wireless Low Area Network), Ethernet or Cheapernet. For this purpose, components 1.1 to 1.n are equipped with data exchange software 3.1 to 3.n. This software 3.1 to 3.n reads a TCP / IP address required for the data exchange and a subnet mask address from a hardware component 4.1 to 4.n, for example an RFID chip, of the respective target computer 1.1 to ln A charging computer 5 activates the target computers 1.1 to 1.n such that the hardware 4.1 to 4.n is released for access by the data exchange software 3.1 to 3.n. The TCP / IP address and the subnet mask address are not part of the software 3.1 to 3.n, but the hardware 4.1 to 4.n of the computer components 1.1 to ln, so that the addressing can not be changed by software intervention is.
