Abstract: An IC card is provided with an IC module. The IC module is provided with a memory section and a control section. The memory section stores information that shows a file structure. The control section receives a first command, transmits a first response containing the information showing the file structure in response to reception of the first command, receives a second command which is transmitted in response to the first response and which includes a first data searched from the information showing the file structure, and sets up the first data in response to reception of the second command.

Abstract: According to one embodiment, an IC card includes an IC module and a substrate. The IC module includes a plurality of communication units, a storage unit, and a controller. The storage unit stores first data, and stores an access condition for the first data. The controller permits, when the access condition includes information which permits an access to the first data based on a reception command received via a first communication unit of the plurality of communication units, an access to the first data based on a first command received via the first communication unit, and does not permits an access to the first data based on a second command received via a second communication unit of the plurality of communication units.

Abstract: An information storage medium includes storage unit for storing first, second, and third data composed of a data structure including identification information which identifies process target data, length information indicating data length of the process target data, and the process target data, communication unit for communicating with a medium processing device, and data processing unit for accessing the process target data included in the second data on the basis of a first command received via the communication unit, the first command specifying the identification information included in the second data and ordering processing of the process target data included in the second data, and subsequently accessing the process target data included in the first data on the basis of a second command including a preceding data specification and ordering processing of the process target data.

Abstract: An authentication data generation method includes receiving an authentication command from an authentication device, determining a communication protocol with the authentication device, changing encryption key reference information contained in the authentication command based upon the determination result of the communication protocol with the authentication device, selecting a target encryption key corresponding to the changed encryption key reference information from a plurality of encryption keys stored in advance, generating authentication data based upon the target encryption key and inclusion data included in the authentication command, and transmitting the authentication data to the authentication device.
