Claims

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 for making a setting to an effect that part or all of functions of the subscriber authentication module mounted in a subscriber terminal equipment should be caused to stop based on settings of an operator operating the authentication vector generating device;a request accepting unit for accepting an issue request of an authentication vector for authenticating the subscriber authentication module via the subscriber terminal equipment;an authentication vector generating unit for generating an authentication vector for authenticating the subscriber authentication module mounted in the subscriber terminal equipment after an issue request of an authentication vector is accepted by the request accepting unit;an addition unit for adding stop information instructing to cause part or all of functions of the subscriber authentication module to stop to the RAND field of the authentication vector generated by the authentication vector generating unit when the setting unit makes a setting to the effect that the functions of the subscriber authentication module should be caused to stop; andan authentication vector transmitting unit for transmitting the authentication vector to which the stop information is added by the addition unit to the authentication device.

2. A subscriber authentication module to be mounted in a subscriber terminal equipment; comprising: a stop information receiving unit for receiving stop information for causing part or all of functions of the subscriber authentication module to stop, included in a RAND field of an authentication vector used for authenticating the subscriber authentication module of a mobile communication network; anda stopping unit for stopping part or all of functions in the subscriber authentication module based on the stop information received by the stop information receiving unit.

3. A mobile communication system comprising an authentication device for authenticating a subscriber authentication module, an authentication vector generating device for generating an authentication vector including a RAND field in response to a request from the authentication device and transmitting the generated authentication vector to the authentication device, and the subscriber authentication module mounted in a subscriber terminal equipment, wherein the authentication vector generating device; includes:a setting unit for making a setting to an effect that part or all of functions of the subscriber authentication module mounted in the subscriber terminal equipment should be caused to stop based on settings of an operator operating the authentication vector generating device;a request accepting unit for accepting an issue request of an authentication vector from the authentication device for authenticating the subscriber authentication module via the subscriber terminal equipment set by the setting unit;an authentication vector generating unit for generating an authentication vector for authenticating the subscriber authentication module mounted in the subscriber terminal equipment after an issue request of an authentication vector is accepted by the request accepting unit;an addition unit for adding stop information instructing to cause part or all of functions of the subscriber authentication module to stop to the RAND field of the authentication vector generated by the authentication vector generating unit when the setting unit makes a setting to the effect that the functions of the subscriber authentication module should be caused to stop; andan authentication vector transmitting unit for transmitting the authentication vector to which the stop information is added by the addition unit to the authentication device, and whereinthe subscriber authentication module; includes:a stop information receiving unit for receiving stop information included in the RAND field of the authentication vector transmitted by the authentication vector transmitting unit; anda stopping unit for stopping part or all of functions in the subscriber authentication module based on the stop information received by the stop information receiving unit.

4. A method of generating an authentication vector of an authentication vector generating device that generates an authentication vector including a RAND field in response to a request from an authentication device authenticating a subscriber authentication module and transmits the generated authentication vector to the authentication device; comprising: a setting step of making a setting to an effect that part or all of functions of the subscriber authentication module mounted in the subscriber terminal equipment should be caused to stop based on settings of an operator operating the authentication vector generating device;an accepting step of accepting an issue request of an authentication vector from the authentication device for authenticating the subscriber authentication module via the subscriber terminal equipment set by the setting step;an authentication vector generating step of generating an authentication vector for authenticating the subscriber authentication module in the subscriber terminal equipment after a request of the authentication vector is accepted by the accepting step;an addition step of adding stop information instructing to cause part or all of functions of the subscriber authentication module to stop to the RAND field of the authentication vector generated by the authentication vector generating step when the setting step makes a setting to the effect that the functions of the subscriber authentication module should be caused to stop; anda transmitting step of transmitting the authentication vector to which the stop information is added by the addition step to the authentication device.
