Abstract: A user authentication based on biometric information is performed and a remittance process is performed based on checking of the fact that a position or a behavior of a user satisfies a setting condition. In an information processing system including a user terminal and a process condition management server, the user terminal includes a control unit that performs a transaction with electronic money associated with a user account and transmits information acquired by a biometric information acquisition sensor and a positional sensor or a behavioral sensor to the process condition management server. The process condition management server performs user authentication based on biometric information, and determines whether the positional or behavioral information satisfies a setting condition, and causes a transaction process in accordance with a registered transaction aspect, for example, a remittance process to the user account to be performed when the positional or behavioral information satisfies the setting condition.

Abstract: A processing unit transforms first input information into first nonlinear transformed information that is transformed into first linear transformed information, and transforms second input information into second nonlinear transformed information that is transformed into second linear transformed information. An exclusive-or section performs an exclusive-or operation based on the first and second linear transformed information. When the first nonlinear and linear transformed information are expressed as a first and second sequence vector, respectively, and the second nonlinear and linear transformed information are expressed as a third and fourth sequence vector, respectively, then a first row vector chosen from a first inverse matrix of a first matrix that transforms the first sequence vector to the second sequence vector, and a second row vector chosen from a second inverse matrix of a second matrix that transforms the third sequence vector to the fourth sequence vector, are linearly independent.

Abstract translation: 处理单元将第一输入信息变换为被变换为第一线性变换信息的第一非线性变换信息，并将第二输入信息变换为被变换为第二线性变换信息的第二非线性变换信息。 独占或部分基于第一和第二线性变换信息执行排他或操作。 当第一非线性和线性变换信息分别表示为第一和第二序列向量时，第二非线性和线性变换信息分别表示为第三和第四序列向量，则从第一个反向 将第一序列向量变换为第二序列向量的第一矩阵的矩阵，以及从第三矩阵变换为第四序列向量的第二矩阵的第二逆矩阵选择的第二行向量是线性独立的。

Abstract: A common-key blockcipher processing configuration with enhanced immunity against attacks such as saturation attacks and algebraic attacks (XSL attacks) is realized. In an encryption processing apparatus that performs common-key blockcipher processing, S-boxes serving as non-linear transformation processing parts set in round-function executing parts are configured using at least two different types of S-boxes. With this configuration, the immunity against saturation attacks can be enhanced. Also, types of S-boxes present a mixture of different types. With this configuration, the immunity against algebraic attacks (XSL attacks) can be enhanced, thereby realizing a highly secure encryption processing apparatus.
