Description
BACKGROUND OF THE
IC card (Integrated Circuit Card) is a card with a microprocessor and memory. It can store and process information in the card and provide various services. Examples of IC cards are electronic money, credit, prepaid, debit, transportation, membership card, and the like. Furthermore, the IC card is also referred to as a smart card because it can store personal information such as an ID card (e-ID card) such as an ID card and a driver's license, and can be used as a more advanced multifunction card. In particular, in the case of an electronic ID card, a large amount of user data such as a photograph or a fingerprint of a user can be stored.
The IC card issuance includes a series of processes of transmitting data to be issued to the IC card owned by the user and recording the data transmitted to the IC card. The IC card issuing process of the terminal can be performed by transmitting data to the IC card through an instruction (e.g., UPDATE Binary command). At this time, after the terminal transmits the data to the IC card through the command, it waits for a response from the IC card as to whether or not the command is successfully received. However, as the data to be transmitted to the IC card through the command becomes large in capacity such as a photograph or a fingerprint, the command should be divided into several times and transmitted to the IC card. The terminal must wait for the response from the IC card for each command.
This command-and-response method requires that a response message to data be continuously transmitted to the terminal until all the data is received from the terminal. Therefore, when the data size is large, unnecessary communication between the terminal and the IC card is required. Is delayed. In particular, it is a major cause of lowering the issuing speed of user data in an IC card environment having a hardware constraint relative to a PC environment.
According to one embodiment, a method of issuing and storing data using an IC card exclusive issuing command, which can shorten the data issuing speed and improve data issuing reliability, is proposed.
A method of issuing data to an IC card using a command according to an embodiment is a method in which a terminal instructs an IC card to receive a memory start address and size information of a page buffer from an IC card, Dividing the data to be issued to the IC card into a plurality of data blocks on a page basis; sequentially issuing, from the first data block to the last data block of the data divided into the plurality of data blocks, And receiving a card response from the IC card for an issuing command including the last data block.
A method of storing data using an instruction word of a terminal according to another embodiment of the present invention includes storing a memory start address and a page buffer size information of an IC card in which data to be issued by the terminal is to be stored, When the terminal divides the data to be issued to the IC card into a plurality of data blocks on a page basis by using the memory start address and size information of the page buffer, From the data block to the last block sequentially through the respective issuing commands and storing the data blocks included in each of the issued issuing commands in the memory, and upon receiving the issuing command including the final data block from the terminal, And transmitting the card response to the terminal.
According to an embodiment, a method of transmitting only a card response to an UPDATE Binary Instruction that contains a final data block of user data, rather than a command-response method through an UPDATE Binary command, to the IC card, a method of transmitting user data transferred from the terminal to an EEPROM The speed of issuing a large volume of user data can be shortened by a method in which the IC card receives a new data block from the terminal during the process of storing the new data block.
Further, it is possible to improve the data issuance reliability by judging whether the data recording error is caused by comparing the interval of the RF power consumption amount generated during the data writing operation of the IC card by the UPDATE binary command of the terminal and the data recording time obtained by the Self_Write command have.
Further, after the IC card stores the data block included in the UPDATE Binary command of the terminal in the EEPROM, it is verified whether or not the data is normally stored. If the verification result is normally stored, the data block is changed to the reception mode and an UPDATE binary command including a new data block The reliability of data issuing can be improved.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention of the user, the operator, or the custom. Therefore, the definition should be based on the contents throughout this specification.
1 is a structural diagram of an application protocol data unit (hereinafter referred to as APDU) command for an IC card.
The present invention is a technique for a terminal to issue user data to an IC card at a high speed. Examples of IC cards are electronic money, credit, prepaid, debit, traffic card, membership card, etc. In particular, the IC card may be an electronic identification card (e-ID card) such as an identification card or driver's license. In this case, the terminal may be a device of an electronic ID card issuing organization. The data issued to the electronic ID card may be a large amount of user data such as a photograph or a fingerprint.
Referring to FIG. 1, a communication protocol between a terminal and an IC card uses an APDU command. The APDU command consists of a Command-APDU command transmitted from the terminal to the IC card and a Response-APDU command transmitted from the IC card to the terminal in response to the Command-APDU command.
Data issuance to the IC card is performed when the terminal transmits a Command-APDU command to the IC card. The IC card receiving the Command-APDU command processes a given job according to the Command-APDU command. The Command-APDU command includes CLA (Class byte), INS (Instruction Code), P1 (Instruction Parameter 1), P2 (Instruction Parameter 2), Lc (Length of Command Data), Data and Le . At this time, CLA is a command class, and INS is a command code including a command class. P1 and P2 are the parameter values for the command, Lc is the length of the data in the command data field, Data is the data for transmitting in the command, and Le is the length of the maximum data expected in the response data field, respectively do.
The response-APDU command transmitted to the terminal by the IC card that has processed the given task according to the Command-APDU command is composed of SW1 (Status Word 1), SW2 (Status Word 2) and Data field. SW1 and SW2 represent the processing state of the command, and Data represents the response data from the IC card.
The APDU command used by the terminal to issue data to the IC card is an UPDATE Binary command. At this time, the terminal divides the data into a plurality of data blocks in order to issue the large-capacity data to the IC card, and transmits the data blocks to the IC card in the data field of the UPDATE Binary command word.

In a nonvolatile memory such as EEPROM or flash, a block write operation is performed on a per page basis, while a volatile memory RAM is written in a cell unit. Therefore, in order to write 1 byte, it is inevitable that a page-level write operation should be performed. In other words, the property of page-by-page writing takes the same amount of time to write one byte for an address in a page or the entire page, for example, 128 bytes or 256 bytes. At this time, the number of bytes of the page is not limited to this, and may vary from company to company.
