Zusammenfassung:A data processing device, in a system performing authentication among a plurality of storage device (IC cards etc.), able to maintain security of authentication at other device even when secrecy of key data held by part of the devices is lost, wherein a key generation unit generates individual key data unique to an IC card based on identification data unique to the IC cards received from the ICs of the IC cards and a card processing unit performs mutual authentication with the IC based on the individual key data.
