    • A terminal device controls delivery of information from a primary delivery destination to a secondary delivery destination. The terminal device stores a primary delivery condition regarding whether delivery of the information to the primary delivery destination is prohibited or permitted, and a trustability value showing a degree of trust of a user in the primary delivery destination. The terminal device judges whether or not to deliver the information to the primary delivery destination, by using the primary delivery condition. When judging to deliver the information, the terminal device calculates a secondary delivery condition using the trustability value and the primary delivery condition, the secondary delivery condition regarding whether delivery of the information from the primary delivery destination to the secondary delivery destination is prohibited or permitted. The terminal device then sends the generated secondary delivery condition to the primary delivery destination.
    • 终端设备控制从主要传送目的地到次要传送目的地的信息传送。 终端设备存储关于是否禁止或允许向主要发送目的地传递信息的主要传送条件,以及示出主要传送目的地中的用户的信任度的可信度值。 终端设备通过使用主要传送条件来判断是否将信息传送到主要传送目的地。 当判断交付信息时,终端设备使用可信度值和主要交付条件来计算二次发送条件,关于是否禁止或允许从主要分发目的地传送信息到次要发送目的地的二次发送条件。 终端设备然后将生成的辅助递送条件发送到主要递送目的地。

    • 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。

    • The data encryption apparatus with a data converting unit splits 256-bit input data into 32-bit data blocks A1, B1, A2, and B2. A first combining unit performs an exclusive OR operation on A1 and B1, and on A2 and B2. A first scramble unit branches A1, A2, and the results of the exclusive OR operations (C1 and C2) into three data blocks each, and for each set of three data blocks, shift-rotates two of the data blocks and combines the shifted data blocks with the remaining data block. A second combining unit performs an exclusive OR operation on D1 and E2, and on D2 and E1, which are the results of the processing performed by the first scramble unit. A block concatenating unit concatenates the results of the operations performed by the second combining unit. A second scramble unit branches the concatenated data into three data blocks, shift-rotates two of the data blocks and combines the two shifted data blocks with the remaining data block.
    • 具有数据转换单元的数据加密装置将256位输入数据分解为32位数据块A1,B1,A2和B2。 第一组合单元对A1和B1以及A2和B2执行异或运算。 第一加扰单元将A1,A2和异或运算(C1和C2)的结果分别分成三个数据块,并且对于每组三个数据块,移位旋转两个数据块,并组合移位的数据 具有剩余数据块的块。 第二组合单元对D1和E2执行异或运算,并且对作为由第一加扰单元进行的处理的结果的D2和E1执行异或运算。 块级联单元连接由第二组合单元执行的操作的结果。 第二加扰单元将连接的数据分成三个数据块,移动旋转两个数据块,并将两个移位的数据块与剩余的数据块组合。
