Abstract
To authenticate an authentication reference apparatus, authentication information generation reference data is transmitted to the authentication reference apparatus. First authentication reference data generated by the authentication reference apparatus using the authentication information generation reference data is acquired from the authentication reference apparatus. Second authentication reference data is generated using key information complying with a method of generating the first authentication reference data and the authentication information generation reference data. The first authentication reference data is compared with the second authentication reference data. The authentication reference apparatus is authenticated based on the comparison result.
