Abstract

See full text

The present invention relates to an information processing apparatus that allows separately forming regions having different roles. When an area definition region #0100h is newly formed under an area definition region #0000h that is formed on an IC card, information of the area definition region #0100h is encrypted using a service key stored in an area registration service definition region #0020h that is formed in advance, and the encrypted information is supplied to the IC card. Upon receiving that information, the IC card decrypts the encrypted information using the service key stored in the area registration service definition region #0020h. Then, the area definition region #0100h is formed based on the result of decryption. The present invention may be applied to an IC card that exchanges information in a non-contact manner and to an apparatus that exchanges data with the IC card.
