Abstract
When a storage section is installed in a controller and the controller is installed in an access device, the controller reads out device ID data and CIS data from the storage section, and certifies the storage section based on the device ID data and the CIS data. Upon completion of the certification of the storage section, the controller reads out boot data and a code key therefrom, and supplies the access device with the read boot data and code key. Subsequently, the access device decodes general data read out from the storage section via the controller, using the code key, and encodes data to be stored using the code key, and writes the encoded data in the storage section via the controller.
