    • According to the present invention, a subscriber identity module in a wireless local area network is authenticated using an authentication vector with no decrease in the confidentiality of the calculation processing, even when a triplet is employed as the authentication vector. An HLR of a mobile communication network comprises an attachment unit for attaching to a RAND field of an authentication vector, which is used to authenticate an SIM in a wireless local area network, information specifying calculation information that is constituted by at least one of an algorithm and secret information for use in the authentication calculation. The SIM, which is mounted on a wireless LAN terminal, comprises a calculation information storage unit storing in advance a plurality of the calculation information, a specification unit for specifying the calculation information to be used in the calculation from the plurality of calculation information stored in the calculation information storage unit by referring to information specifying the calculation information, and a calculation unit for performing the calculation on the basis of the specified calculation information.
    • 根据本发明,即使采用三元组作为验证向量,无线局域网中的用户身份模块也使用认证向量进行认证,而不会降低计算处理的机密性。 移动通信网络的HLR包括用于附加到用于在无线局域网中认证SIM的认证向量的RAND字段的附件单元,指定由以下各项中的至少一个构成的计算信息的信息: 以及用于验证计算的秘密信息。 安装在无线LAN终端上的SIM包括预先存储多个计算信息的计算信息存储单元,用于从存储在多个计算信息中的多个计算信息指定计算中使用的计算信息的指定单元 计算信息存储单元通过参考指定计算信息的信息,以及计算单元,用于根据指定的计算信息进行计算。

    • Authentication of a subscriber identity module issued by IMT-2000 network operator is performed with no decrease in the confidentiality of calculation processing, even in cases such as when a roaming network is a GSM network. An HLR of an IMT-2000 mobile communication network comprises an algorithm information attachment unit for attaching, to a RAND field of an authentication vector used to authenticate a USIM, information specifying an algorithm to be used in the authentication calculation. The USIM, which is mounted on a mobile equipment, comprises an algorithm storage unit storing in advance a plurality of algorithms for use in the authentication calculation, a specification unit for specifying the algorithm to be used in the calculation from among the plurality of algorithms stored in the algorithm storage unit by referring to the algorithm-specifying information included in received data, and a calculation unit for performing the calculation on the basis of the specified algorithm using the received data.
    • 即使在漫游网络是GSM网络的情况下,也可以不进行IMT-2000网络运营商发行的用户识别模块的认证,而不会降低计算处理的机密性。 IMT-2000移动通信网络的HLR包括用于将用于认证USIM的认证向量的RAND字段附加到用于认证计算中使用的算法的信息的算法信息附加单元。 安装在移动设备上的USIM包括预先存储用于认证计算中的多种算法的算法存储单元,用于从存储的多个算法中指定要用于计算的算法的指定单元 在算法存储单元中通过参考包括在接收数据中的算法指定信息,以及计算单元,用于使用接收到的数据基于指定的算法来执行计算。
