ABSTRACT:
In an IC card, an operating system manages the access order of each channel for each file using a channel management table. An application controls access to each file based on the access order managed in the channel management table. The channel management table stores, as an access order, an order that each logical channel has set a file in a current state. If current setting by a specific logical channel is canceled, a table updating function deletes the logical channel from the channel management table and moves up the access order of each logical channel next to the deleted logical channel.
