    摘要： The present invention makes it possible to determine whether there is actually a fault that has occurred in a situation where a specific fault state pertaining to a system to be monitored is continuously detected. An operation management device detects, using the measured value of a performance index pertaining to the system to be monitored and a correlation model representing the relationship between two mutually different performance indices, fault information indicating a fault pertaining to the combination of the two mutually different performance indices. The operation management device holds the detected fault information in chronological order, and determines, on the basis of the fault information, whether the fault information has been detected continuously with respect to a specific combination. The operation management device calculates an abnormality score representing the degree of abnormality pertaining to the performance index on the basis of information that pertains to the combination for which it is determined that the fault information is detected continuously, and information that pertains to other combinations including the specific performance index, among the combinations including the specific performance index and for which the fault information has been detected.

    摘要： A redundant device unit includes a first device connected with a field device via a first link and a second link in series. The first device, initially active in use, when active sends diagnostic information indicating whether there is a fault in the first link and/or the second link. A second device connected with the field device via the second link and a third link in series, initially passive in use, receives the first diagnostic information from the first device. When the first diagnostic information indicates that there is a fault in the first link and/or the second link, the first device switches to passive and the second device switches to active and generates second diagnostic information indicating whether there is a fault in the second link and/or the third link. A determination regarding the fault is made based on the first and second diagnostic information.

    摘要： A fault detection method for an encryption/decryption system based on a block cipher comprises the steps of subjecting a state array (CST) to multiple rounds, each round comprising a same series of sequential operations transforming the state array; storing the state of a reference operation (ShiftRows) of a current round as a checkpoint state (CHK); storing the state of the reference operation in the next round as an intermediate state; applying one round of reciprocal operations to the intermediate state, starting from the reciprocal of the reference operation (InvShiftRows); and comparing the result state of said one round of reciprocal operations with the checkpoint state.
