Abstract:
1. An authentication vector generating device for generating an authentication vector including a RAND field in response to a request from an authentication device for authenticating a subscriber authentication module and transmitting the generated authentication vector to the authentication device; comprising: a setting unit configured to make a setting indicating that part or all of functions of the subscriber authentication module mounted in a subscriber terminal equipment should be caused to stop based on an input received from an operator operating the authentication vector generating device; a request accepting unit configured to accept an issue request of the authentication vector for authenticating the subscriber authentication module via the subscriber terminal equipment; an authentication vector generating unit configured to generate the authentication vector for authenticating the subscriber authentication module mounted in the subscriber terminal equipment after the issue request of the authentication vector is accepted by the request accepting unit, the authentication vector including the RAND field where a random number is written for authentication processing; an addition unit configured to add stop information to the RAND field of the authentication vector, the stop information being a character string separate from the random number stored in the random number field and being an instruction which causes part or all of functions of the subscriber authentication module to stop, when the setting unit makes the setting indicating that part or all of the functions of the subscriber authentication module should be caused to stop, such that the RAND field of the authentication vector includes both a portion for the random number for authentication processing and a portion for the stop information; and an authentication vector transmitting unit configured to transmit the authentication vector, to which the stop information is added by the addition unit, to the authentication device.
