Abstract:
A system including first and second IC cards and a host device adopts a communication mode in which the host device communicates with the first IC card only, and the first IC card communicates with the second IC card. The host device acquires inherent information encrypted by the first and second IC cards via the first IC card, decrypts the inherent information encrypted by the first and second IC cards, and collates the decrypted information with the inherent information to thereby authenticate the first and second IC cards.
