摘要： PROBLEM TO BE SOLVED: To provide a storage device whose security can be easily enhanced.SOLUTION: When power is supplied to a storage part comprising a nonvolatile semiconductor memory, a storage device of an embodiment starts counting of elapsed time. When a command is input from a host device, a calculation part calculates the elapsed time from the previous command input to the current command input on the basis of time information, which indicates the present date and time that are timed by the host device, and a counter value that is obtained by counting before the command input. A time information determination part determines a match between time information, on the basis of a magnitude relation with respect to time between an addition result, which is obtained by adding the calculated elapsed time to time information contained in the previously input command, and the time information contained in the currently input command. When a mismatch is determined, an invalidation part invalidates data stored in the storage part.
摘要翻译：要解决的问题：提供一种能够容易地提高安全性的存储装置。解决方案：当向包括非易失性半导体存储器的存储部件供电时，实施例的存储装置开始计时经过时间。当从主机设备输入命令时，计算部分基于指示由主机设备定时的当前日期和时间的时间信息来计算从先前的命令输入到当前命令输入的经过时间，以及在命令输入之前通过计数获得的计数器值。时间信息确定部分基于通过将计算出的经过时间与包含在先前输入的命令中的时间信息相加得到的相加结果与时间信息之间的时间的大小关系来确定时间信息之间的匹配，当前输入命令中包含的信息。当确定不匹配时，无效部分使存储部分中存储的数据无效。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a storage device capable of protecting stored user data from being illegally read.SOLUTION: A storage device having a nonvolatile semiconductor memory comprises an authentication information storage part that stores, in advance, first device authentication information for authenticating an authorized host device having a connection authority and first user authentication information for authenticating an authorized user. The storage device performs a device authentication on the basis of second device authentication information received from a current host device that has been newly connected and the first device authentication information in the authentication information storage part; and, if the device authentication fails, performs invalidation processing to set a state in which user data stored in the memory cannot be read.

摘要： PURPOSE:To improve the physical protection properties for operation of a plant by providing an access adaptability deciding part to lock a fact itself that an outsider gives an access to a controller via a man-machine interface. CONSTITUTION:An access propriety deciding part 3 supplies a conditional signal for permission of access to a monitor controller, a plant state signal received from a plant and an access permission request signal received from a control part 2. Then the part 3 decides whether an access to the monitor and control equipment is possible or not. If the access is impossible, a request signal given from a man-machine interface part 1 is neglected. So that it is possible to lock a fact itself that an outsider gives an access to the controller via a man- machine interface 11. As a result, the possibility where the outsider gives an access to the controller is reduced and the physical protection properties can be increased for operation of the plant.

摘要： PURPOSE:To find faults on an output converter and a load side in their early stages and to prevent abnormal operation by outputting the drive testing signal and actual driving signal of a load alternately and cyclically, and comparing the testing signal and response signal of the load with each other. CONSTITUTION:A control computing element 2 receives input signals b1-b3 from input converters 1 all the time to perform control operations and supplies output signals c1-c3 to output signal switches 5. The switches 5 receive the output signals c1-c3, and test mode signals e1-e3, test signals f1-f3, and output and test mode signals e1-e3, test signals f1-f3, and output gate signal g1-g3 from a test signal generator and comparator 7 to switch the output signals c1- c3 and test signals f1-f3, obtaining output signals h1-h3. Those output signals h1-h3 are converted by output converters 3 into load signals d1-d3, which are inputted to load signal detectors 6 to be fed back to the test signal generator and comparator 7 as response signals j1-j3. The comparator compares test signals e' with the response signals j1-j3 to output comparison result output gate signals g1-g3 to the output signal switches 5.
