An authentication system includes a mobile station 1, a base station 2, a mobile station controller 3, and a data base 4. When the base station determines that authentication is required, an authentication calculation request is generated with respect to the mobile station with a random number generated as an authentication random number by the base station. An authentication calculation result 22 as a response from the mobile station is received by the base station. The base station initiates the mobile station controller by using the authentication random number 21, the authentication calculation result 22, and the identification number of the mobile station as set parameters of a signal. The mobile station controller receives the authentication calculation result 25 in the set parameters of the signal received from the base, collates 8 the authentication calculation result in the set parameters of the signal received from the base station with the authentication calculation result as a response sent from the data base, and determines that authentication confirmation is made, if a collation result indicates coincidence. <IMAGE>
