Problems solved by technology

[0006] As mentioned above, there is a problem that conventional IC cards may perform illegal operations combining command APDUs with external attacks
[0007] Furthermore, the technique disclosed in Japanese Patent Laid-Open No. 2000-222202 has problems of increased processing load and processing time related to conversion or reverse conversion
In addition, although the command APDU converted and recorded in the memory is not executed, there is a possibility that the illegal operation is performed when the reverse-converted command APDU is executed

Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038]FIG. 1 is a block diagram showing an example of the composition of various devices used in the recording method in which the IC card of the present invention is used. Reference numeral "1" in the figure denotes an IC card, which is a recording device. The IC card 1 is capable of communicating with an external device 2, which is a reading device-recording device with or without contact with the IC card 1, and by bringing the IC card 1 close to the external device 2, the external device 2 transmits Information defined by standards such as ISO / IEC7816-4, such as a command APDU (Application Protocol Data Unit), and on the IC card 1, processing is performed based on the command shown by the received information, and as a response to the outside Device 2 transmits the execution result. Various orders and information such as personal in...

Abstract

In an IC card provided with a recording unit having a plurality of recording areas designated by continuous addresses, a unit for executing a command based on information recorded in the recording unit, and a unit for communicating with an external apparatus, when the information received from the external apparatus is recorded in the recording unit, the information is divided and recorded in the plurality of recording areas designated by discontinuous addresses.

Description

technical field [0001] The present invention relates to a recording method for recording information on an IC card, a recording device using the recording method, and an IC card using the recording method, in particular, to an A recording method, a recording device, and an IC card of an illegal program. Background technique [0002] Compared with magnetic cards, IC cards on which memories such as ROM and RAM and a CPU are loaded can record a large amount of data and have higher security. This provides conditions for the further popularization of IC cards in the future. By making such an IC card communicate with an external device (reading device-recording device) for performing information recording / reading with or without contact therewith, the external device will be defined by standards such as ISO / IEC7816-4, etc. Information commanding APDU (Application Protocol Data Unit) is transmitted to the IC card, the IC card performs processing according to the received informat...
