摘要： Processed results are received when processors make compatible computations on data of a common object. A computation command signal is generated and fed to the processors in response to a start signal from any one of the processors so that the processors can make computations with different operation timings. Then, the results of the computations made by the processors are compared with each other. Thus, apparatus capable of small size, high performance and safety at the same time can be achieved by the above construction using the processors.

摘要： Eine Aufgabe der vorliegenden Erfindung liegt darin, ein Sicherheitsüberwachungssystem und ein Sicherheitsüberwachungsverfahren bereitzustellen, welches schnell reagieren kann, wenn ein unautorisierter Zugriff, ein Schadprogramm oder Ähnliches detektiert werden, während ein Normalbetrieb des Steuerungssystems durch eine fehlerhafte Detektion nicht unterbrochen wird. Das Sicherheitsüberwachungssystem 100 ermittelt Kommunikationspakete in Segmenten 3, die das Steuerungssystem 1 bilden, und extrahiert ein Kommunikationspaket, das einen charakteristischen Wert hat, welcher sich von einem Normalwert aus den ermittelten Kommunikationspaketen unterscheidet, um Kommunikationsereignis-Informationen 150 zu erzeugen. Das Sicherheitsüberwachungssystem 100 sagt einen Grad des Einflusses des extrahierten Kommunikationspakets aus der Kommunikationsereignis-Information 150 auf das Steuerungssystem 1 durch den Vergleich der Kommunikationsereignis-Information 150 mit Ereignismustern voraus, welche die Eigenschaften den unautorisierten Zugriffs oder dergleichen charakterisieren.

摘要： Es werden ein Steuersystem und eine Authentifikationsvorrichtung, die eine Anomalie einer Entwicklungsvorrichtung zum Verteilen eines Steuerprogramms detektieren kann und eine durch die Anomalie verursachte Zerstörung und Manipulation des Steuerprogramms verhindern kann, geschaffen. Um das obige Problem zu lösen, wird geschaffen: eine Steuervorrichtung, die ein gesteuertes Objekt steuert; eine Entwicklungsvorrichtung, die mehrere durch die Steuervorrichtung ausgeführte Steuerprogramme managt und das vorgegebene Steuerprogramm und dem Steuerprogramm beigefügte Informationen an das Netz sendet; und eine Authentifikationsvorrichtung, die eine Authentifikationsliste besitzt, die die das Steuerprogramm begleitenden Informationen dem Steuerprogramm zugeordnet speichert. Beim Empfang des Steuerprogramms und der dem Steuerprogramm beigefügten Informationen von der Entwicklungsvorrichtung führt die Authentifikationsvorrichtung eine Authentifikation aus, ob die Entwicklungsvorrichtung normal ist, indem sie die von der Entwicklungsvorrichtung empfangenen beigefügten Informationen mit den in der Authentifikationsliste gespeicherten Informationen prüft.
