Execute the process.

Next, the details of the on-board issuing process will be described. As shown in FIG. 1, when purchasing a vehicle-mounted device from a retail store 12, a user 11 obtains, together with the vehicle-mounted device 2, an empty issuance IC card 3A in which no data is recorded and an application for issuance.

The vehicle-mounted device 2 sold at the retail store 12 includes:
A vehicle-mounted device ID unique to all vehicle-mounted devices and a key unique to the vehicle-mounted device for the vehicle-mounted device 2 to authenticate and decrypt the issuing IC card 3A at the time of issuance are recorded in advance.
At this time, the key is kept secret so that the user 11 cannot visually determine it, but the in-vehicle device ID is clearly indicated on the outside of the case or the like so that it can be visually determined.

Also, in order to prevent anyone other than the authorized person from writing information on the issuing IC card 3A without permission, at the time of writing processing, a partner authentication mechanism using a password or the like known only by the issuing processing office 13 is used. have. Then, the user 11 enters the name, address, telephone number, vehicle type, license plate, and
D and the like are described, and are sent to the issuance processing office 13 by mail or the like together with the issuance IC card 3A.

The issuance processing office 13 that has received the issuance IC card 3A and the issuance application form,
The issuance data generated based on the contents described in the application form is written into the issuance IC card 3A according to a predetermined procedure. At this time, the issuance data is encrypted and issuance IC card 3A
Is written to. This cipher text is encrypted using a key calculated based on the OBE ID described in the application, and this key is the same as the key recorded in the OBE 2 corresponding to the OBE ID. Therefore, only the in-vehicle device 2 has a ciphertext that can be decrypted. The purpose of this encryption is to conceal information related to the privacy of the user recorded inside the issuance IC card 3A in the process of returning the issuance IC card 3A.

Hereinafter, detailed operations of the data writing process to the issuing IC card 3A by the issuing processing device 20 and the on-board unit issuing process using the issuing IC card 3A will be described with reference to flowcharts shown in FIGS. explain.

FIG. 5A is a flowchart showing the operation of the issuance data writing processor 21 in the issuance processing device 20, and FIG. 5B is a flowchart showing the operation of the issuance IC card 3A. When the issuance IC card 3A is attached to the issuance processing device 20,
As shown in the flowchart of FIG. 5, power is supplied from the issue processing device 20 to the issuance IC card 3A, and initial processing is executed (step B1).

On the other hand, the operator of the issuance processing device 20 inputs the issuance data generated based on the data described in the application form by key operation (step A1). This input data is transmitted to the human interface 23 as shown in FIG.
Is sent to the issuance data writing processing unit 21 via Next, the issuance processing device 20 and the issuance IC card 3A perform a mutual authentication operation (step A2, step B).
2), determine the authentication result (step A3, step B3). When the issuance data writing processing unit 21 determines that the authentication has been correctly performed, the fact is displayed on the display unit. After confirming the authentication result, the operator inputs the IC card password (step A4). This password is transmitted from the issuance data writing processing unit 21 to the issuance IC card 3A. Upon receiving the password, the issuing IC card 3A checks the password (step B4),
The response of the password verification result is issued data writing processing unit 2
1 is returned (step B5). The issuing IC card 3A determines whether or not the password has been correctly verified (step B6). If the password is correct, the blockage of the read / write function is released (step B6).
7) Prepare to receive the issued data.

On the other hand, when receiving the password collation response from the issuance IC card 3A (step A5), the issuance data writing processor 21 generates an encryption key (step A6), and encrypts the issuance data using the encryption key. And sends it to the issuing IC card 3A (steps A7, A8).

Upon receiving the issuance data sent from the issuance data write processing unit 21, the issuance IC card 3A stores the data in the memory (step B8) and returns a data write response (step B9). The processes of steps B8 and B9 are repeatedly executed each time the above-mentioned issue data is received.

After transmitting the issuance data, the issuance data write processing unit 21 determines whether or not a data write response has been sent from the issuance IC card 3A (step A9). If not, the issuing data is transmitted again. Then, upon receiving the data write response, it issues an "OK" processing end notification to the issuing IC card 3A.
(Step A10), and if there is no data write response after repeating the transmission of the issuance data a preset number of times, an "NG" processing end notification is transmitted to the issuance IC card 3A (Step A11). . If it is determined in step A3 that the authentication result is "NG", or if the password verification response is "N" in step A5.
Even when it is determined to be "G" or "None", the processing completion notification of "NG" shown in step A11 is performed.

The issuing IC card 3A is stored in the step B
After returning the data write response in step 9, it is determined whether or not an "OK" or "NG" processing end notification has been sent from the issued data write processing unit 21 (step B10).
When the process completion notification of “OK” is sent, the process ends normally. The issuance IC card 3A reads / writes when the "NG" processing end notification is sent from the issuance data writing processing unit 21 or when the processing end notification is not sent within a predetermined time. The write function is closed (step B11), and the process ends without issuing data being written. If it is determined in step B3 that the authentication result is "NG", or if it is determined in step B6
If the password collation is determined to be "NG" in step B11, the read / write function closing process shown in step B11 is executed.

The issuance processing office 13 writes the issuance data to the issuance IC card 3A as described above, and returns to the user 11 the issuance IC card 3A in which the issuance data has been correctly written.

The user 11 performs the on-board unit issuing process using the issuing IC card 3A returned from the issuing processing office 13. Hereinafter, details of the vehicle-mounted device issuing process by the issuing IC card 3A will be described with reference to the flowchart shown in FIG. FIG. 6A is a flowchart showing the operation of the vehicle-mounted device 2, and FIG. 6B is a flowchart showing the operation of the issuing IC card 3A. The user 11 mounts the issuing IC card 3A returned from the issuing processing office 13 on the vehicle-mounted device 2 as shown in FIG. 2, and turns on the power of the vehicle-mounted device 2 as shown in FIG. D1). As a result, the initial processing of the vehicle-mounted device 2 is executed, and the I
Power is supplied to the C card 3A, and an initial process is executed (step D1). At this time, the issuing IC card 3
A is a state in which the read / write function closed state has been released.

Next, the issuance IC card 3A and the on-vehicle device 2 mutually perform an authentication operation, and confirm that the media are authentic media (Step C2, Step D2). In addition, the issuing IC card 3A receives the vehicle-mounted device ID from the vehicle-mounted device 2.
Is read, and it is confirmed whether or not this in-vehicle device ID matches the issuance destination in-vehicle device ID recorded in the issuing IC card 3A.

Thereafter, the issuing IC card 3A determines the authentication result (step C3), and if the authentication result is “OK” and the IDs match, the encrypted issuing data is sent to the vehicle-mounted device 2. Transmit (step C4). If the authentication result is "NG" or the IDs do not match, the process is terminated as it is, and the transfer of the information in the issuing IC card 3A to the outside is prohibited.

On the other hand, the vehicle-mounted device 2 determines whether or not the authentication result is "OK" when performing the mutual authentication in step D2 (step D3). It receives the issuance data sent from the card 3A (step D4), decrypts the code and stores it in the internal memory (step D5). Then, the result of writing the data is determined, and if "NG", the process returns to step D4 to retry. If the number of retries for issuing data has exceeded the set number of times, a "NG" processing end notification is sent to the issuing IC card 3A (step D8), and the processing ends in an unissued state. If the result of the data writing in step D6 is "OK", an "OK" processing end notification is sent to the issuing IC card 3A.

After transmitting the issuance data in step C4, the issuing IC card 3A determines whether or not a processing end notification has been sent from the vehicle-mounted device 2, and upon receiving the "OK" processing end notification, reads the / Block write function. That is, in order to prevent reuse of the same issuing IC card 3A, the data input / output function between the issuing IC card 3A and the outside is frozen unless a specific decompression procedure known only to the issuing processing office 13 is performed. However, the issuing IC card 3A
Keeps only the minimum external data reading function necessary to perform the decompression procedure operable. Then, the issuing IC card 3A notifies the in-vehicle device 2 that the read / write function has been closed, and ends the issuing process normally.
Note that in step C5, when the process end notification of “NG” is received from the vehicle-mounted device 2, or when the process end notification is not sent within a predetermined time, the process is performed with the issuing process in an incomplete state. finish.

The vehicle-mounted device 2 determines whether or not the read / write function block notification has been sent from the issuing IC card 3A (step D9). The issuing process ends normally. The notification of blockage of the read / write function from the issuing IC card 3A is "N
If "G", or if the notice of blocking of the read / write function has not been sent within a predetermined period of time, the process ends without being issued.

The issuing process for the vehicle-mounted device 2 is completed as described above, and the issuing IC card 3A is taken out of the vehicle-mounted device 2. The in-vehicle device 2 that has completed the issuance processing includes an IC for charge settlement.
By attaching the card, automatic toll collection processing can be performed for a tollgate on a toll road.

In the above embodiment, when the user 11 purchases the vehicle-mounted device 2 from the retail store 12, the user 11 acquires the issuing IC card 3A and the application, and issues the issuing IC card 3A and the application. Although the mail is sent to the handling office 13 by mail or the like, the issuing process of the vehicle-mounted device 2 may be performed by the following method.

That is, an empty issuance IC card 3A is prepared in advance in the issuance processing office 13. Then, when the user 11 purchases the vehicle-mounted device 2 from the retail store 12, only the application form is obtained, necessary items are described in the application form, and the application form is sent to the issuance data writing processing section 21. Issue processing office 13
Writes the issuance data in the issuance IC card 3A based on the items described in the application form sent from the user 11 and sends the data to the user 11.

When the above method is used, the user 11
Need only send the application form to the issuance office 13 and there is no need to send the issuing IC card 3A.
Application to the issuance processing office 13 becomes easy.

[0041]

As described above in detail, according to the present invention, when purchasing a vehicle-mounted device from a retail store, a user obtains an issuance IC card and an application form, and obtains the issuance IC card and the application form. Since the issuance data is sent to the issuance office and the issuance data is recorded on the issuance IC card, the burden on the user can be significantly reduced. That is, since the IC card is highly portable, the IC card can be easily sent to the issuing processing office using a means such as mailing. Further, since the user simply attaches the issuing IC card sent from the issuing processing office to the vehicle-mounted device, the issued data is transferred to the vehicle-mounted device and the issuing process is performed.

Also, an issuance IC card is prepared in advance at the issuing processing office, and the user sends only the application form to the issuing processing office. If the issuance data is written to the issuance IC card based on the issuance and sent to the user, the burden on the user can be further reduced.
