Abstract
An IC card compatible with a DES scheme and an AES scheme having a security strength different from that of the DES scheme, includes an inhibition information receiving section for receiving inhibition information for inhibiting predetermined manipulation from being performed in a storage region of the IC card using the DES scheme from an issuing device using the AES scheme, an inhibition flag setting section for performing inhibition processing for inhibiting the predetermined manipulation by the inhibition information, a manipulation request receiving section for receiving a manipulation request from a service providing device or the issuing device, and a manipulation executing section for executing the requested manipulation if the requested manipulation does not correspond to the predetermined manipulation inhibited by the inhibition information.
