Abstract
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.
