Title: SPOOFING SENSING SYSTEM
Abstract:
An authentication server 3 executes a phase-1 cross-authentication with a terminal device 1 when a login to a prescribed service occurs, and repeatedly carries out a phase-2 cross-authentication with the terminal device 1 during at least an interval from a logout from the prescribed service to the next login to the prescribed service. The terminal device 1 promptly executes the phase-1 cross-authentication if a failure in the phase-2 cross-authentication is detected, and determines that a spoofing attack has occurred if the phase-1 cross-authentication has failed.
