    • To aim to provide an information security device capable of reducing a period necessary for performing a power operation used for secret communication or authentication. The information security device performs secret communication or authentication by calculating an exponentiation X^d based on target data X and a secret value d using the window method. In the process of calculating the exponentiation X^d, immediately after square of a random value R acquired for multiplication is repeatedly performed a predetermined number of times, for example 256 times, a result of square of the random value R is cancelled using a cancellation value S (=R^(−2^256)). This makes it unnecessary to perform cancellation processing that has been conventionally performed.
    • 旨在提供能够减少执行用于秘密通信或认证的电力操作所需的时间的信息安全装置。 信息安全装置通过使用窗口方法计算基于目标数据X的乘数X ^ d和秘密值d来执行秘密通信或认证。 在计算乘数X ^ d的过程中,在乘法获得的随机值R的正方形之后立即重复执行预定次数(例如256次),使用取消来取消随机值R的平方的结果 值S(= R ^( - 2 ^ 256))。 这使得不需要执行常规执行的取消处理。

    • A detection apparatus (102) connected to a device in a residence and an electricity meter (100) indicating an amount of electric power consumed by the device in the residence, the detection apparatus (102) including: a reception unit (1021) which receives the amount of electric power from the electricity meter (100); a collection unit (1024) which collects usage status of the device; a device information holding unit (1027) which holds device information including the usage status of the device and electric power consumption of the device corresponding to the usage status; and a determination unit (1025) which determines whether or not the electricity meter (100) is tampered, by comparing an estimated electric power consumption amount with the amount of electric power received by the reception unit (1021), the estimated electric power consumption amount being estimated from the usage status of the device by using the device information, in which the determination unit (1025) determines that the electricity meter (100) is tampered, when a difference between the estimated electric power consumption amount and the amount of electric power received by the reception unit (1021) is equal to or more than a predetermined threshold.
    • 一种连接到住宅内的装置的检测装置(102)和表示该住宅内的装置消耗的电力量的电表(100),检测装置(102)包括:接收部(1021),其接收 来自电表(100)的电力量; 收集单元(1024),其收集所述设备的使用状态; 装置信息保持单元,其保存包括与所述使用状态对应的所述装置的使用状态和所述装置的电力消耗的装置信息; 以及确定单元(1025),其通过将估计的电力消耗量与由所述接收单元(1021)接收的电力量进行比较来确定所述电表(100)是否被篡改,所述估计电力消耗量 通过使用其中确定单元(1025)确定电表(100)被篡改的设备信息,根据估计的电力消耗量和电力量之间的差异来估计设备的使用状态 由接收单元(1021)接收的信号等于或大于预定阈值。
