Abstract: Using sensor data indicating a state of a control target (2) outputted from a sensor (3) and a control input to control the state of the control target (2), a state estimation unit (4a) of a controller (4) calculates an estimate of the state of the control target (2). Further, a calculation unit (4b) of the controller (4) calculates the control input to which colored noise in a predetermined frequency band is added, according to the calculated estimate of the state of the control target (2).

Abstract: An update device includes processing circuitry configured to store package management information that includes associations between files and packages including the files and information indicating existence/non-existence of dependence relationships among the packages, and an access control list that includes associations between the files and access source files permitted to access the files, refer, when a combination of a file and an access source file is specified, to the package management information to identify a package including the file and a package including the access source file, and add, when the identified package including the file and the identified package including the access source file are the same or are mutually in a dependence relationship, the specified combination to the access control list.

Abstract: A trusted application (TA) operates on a trusted execution environment (TEE) and generates a screen. Further, the TA transmits certification information for certifying validity of the TA to a verification device. The verification device verifies whether the TA is valid on the basis of the certification information. Further, the verification device authenticates a display device when the validity of the TA is certified and when the verification device is capable of confirming the facts that a picture is being output and that a device outputting the picture is the display device. Further, the verification device outputs a random number code when the display device is authenticated. Further, the verification device transmits the random number code to the display device when the display device is authenticated. Further, the display device receives the random number code from the verification device and displays the same.

Abstract: An information processing device includes processing circuitry configured to determine whether or not there is integrity in predetermined data regarding a boot sequence of an Operating System (OS) during execution of shutdown of the OS, arid suspend shutdown of the OS when it is determined that there is no integrity in the predetermined data.

Abstract: An information processing apparatus includes a normal user interface (NUI) functional unit, a secure user interface (SUI) functional unit having a protection level higher than that of the NUI functional unit, and an input/output unit that receives an input of information and displays and outputs the information. The NUI functional unit causes the input/output unit to display a NUI screen which receives an input of a query and transmits, as a query, the query input via the NUI screen to the SUI functional unit. The SUI functional unit produces a summary corresponding to the query on the basis of certification data including a query and a summary corresponding to the query and causes the input/output unit to display a SUI screen having the query and the summary.

Abstract: An information processing apparatus (1) includes a NUI functional unit (30), a SUI functional unit (20) having a protection level higher than that of the NUI functional unit (30), and an input/output unit (11) that receives an input of information and displays and outputs the information. The NUI functional unit (30) causes the input/output unit (11) to display a NUI screen which receives an input of a query Q0 and transmits, as a query Q1, the query Q0 input via the NUI screen to the SUI functional unit 20. The SUI functional unit (20) produces a summary M1 corresponding to the query Q1 on the basis of certification data (50) including a query and a summary corresponding to the query and causes the input/output unit (11) to display a SUI screen having the query Q1 and the summary M1.

Abstract: In a detection system (1) including a sensor (2) and a controller (3), an acquisition unit (2a) in the sensor (2) acquires sensor data, a calculation unit (2b) calculates, by using the sensor data, a MAC value from which non-tampering of the sensor data is verifiable, and a transmission unit (2d) transmits the sensor data to the controller (3) or transmits the MAC value to the controller (3) in place of the sensor data when the calculation unit (2b) has calculated the MAC value. In the controller (3), a reception unit (3a) receives the sensor data or the MAC value transmitted from the sensor (2), and when the reception unit (3a) has received the MAC value, a verification unit (3b) verifies the MAC value by using the sensor data last received by the reception unit (3a).

Abstract: This invention relates to the method and apparatus for improving the cast ingot, cast in a continuous casting equipment which is commonly called a "belt-and-wheel" system wherein a casting wheel and a metallic belt are employed, by applying a light reduction to the cast ingot to give elongation under compressive stress during the process wherein the curvature of the cast ingot changes as the cast ingot travels from the exit of a casting wheel.More particularly, this invention relates to cast ingot quality improvement method and apparatus in a continuous casting which aims at preventing cracks which were liable to occur on the groove bottom side of the ingot cast by the said continuous process; similarly it also aims at crushing blow holes which tended to concentrate on the groove bottom side the cast ingot.
