[0019]
Next, the details of the issuing process of the vehicle-mounted device will be described.
As shown in FIG. 1, when a user 11 purchases an in-vehicle device from a retail store 12, the user 11 obtains an empty issuance IC card 3 </ b> A in which no data is recorded and an issuance application form together with the in-vehicle device 2.
[0020]
The vehicle-mounted device 2 sold at the retail store 12 has a unique vehicle-mounted device ID and a unique vehicle-mounted device ID for authenticating the IC card 3A for issuance at the time of issuance. The key is recorded as information. At this time, the key is concealed so that it cannot be visually judged by the user 11, but the vehicle-mounted device ID is clearly indicated on the outside of the case so that it can be visually judged.
[0021]
In addition, the issuing IC card 3A has a mechanism for authenticating the other party by means of a password or the like known only to the issuing processing office 13 during the writing process so that only authorized persons can write information without permission. ing. Then, the user 11 describes predetermined information such as name, address, telephone number, vehicle type, license plate, vehicle-mounted device ID, etc. in the issuance application form, along with the issuance IC card 3A. Send to 13 by mail.
[0022]

This ciphertext is encrypted using a key calculated based on the vehicle-mounted device ID described in the application form. This key is identical to the key recorded in the vehicle-mounted device 2 corresponding to the vehicle-mounted device ID. Therefore, only the vehicle-mounted device 2 is a ciphertext that can be solved. The purpose of this encryption is to conceal information relating to the privacy of the user recorded in the issuing IC card 3A in the process of returning the issuing IC card 3A.
[0023]
Hereinafter, detailed operations of the data writing process to the issuing IC card 3A by the issuing processing device 20 and the vehicle-mounted device issuing process using the issuing IC card 3A will be described with reference to the flowcharts shown in FIGS.
[0024]
FIG. 5A is a flowchart showing the operation of the issuance data write processing unit 21 in the issuance processing apparatus 20, and FIG. 5B is a flowchart showing the operation of the issuing IC card 3A.
When the issuing IC card 3A is installed in the issuing processing device 20, power is supplied from the issuing processing device 20 to the issuing IC card 3A as shown in the flowchart of FIG. 5, and an initial process is executed (step B1).
[0025]
On the other hand, the handler of the issuance processing device 20 inputs the issuance data generated based on the description data of the application form by key operation (step A1). This input data is sent to the issuance data write processing unit 21 via the human interface 23 as shown in FIG.
Next, the issuance processing device 20 and the issuing IC card 3A mutually perform an authentication operation (step A2, step B2), and determine the authentication result (step A3, step B3). When the issuance data write processing unit 21 determines that the authentication is correctly performed, the issuance data write processing unit 21 displays that fact 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 write processing unit 21 to the issuance IC card 3A. When issuing the IC card 3A receives the password, it verifies the password (step B4), and returns a response of the password verification result to the issued data write processing unit 21 (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 reading / writing function is unblocked (step B7), Prepare for acceptance.
[0026]
On the other hand, when the issuance data write processing unit 21 receives the password verification response from the issuance IC card 3A (step A5), it generates an encryption key (step A6) and encrypts the issuance data with the encryption key and issues it. To the IC card 3A (steps A7 and A8).
[0027]
Issuing IC card 3A receives the issuance data sent from issuance data write processing unit 21, stores the data in memory (step B8), and returns a data write response (step B9). The processes in steps B8 and B9 are repeatedly executed every time the issued data is received.
[0028]
The issuance data write processing unit 21 determines whether or not a data write response has been sent from the issuance IC card 3A after transmitting the issuance data (step A9). Send the data again. When a data write response is received, an “OK” process end notification is transmitted to the issuing IC card 3A (step A10). Even if the transmission of the issued data is repeated a predetermined number of times, the data write response is received. If not, a processing end notification of “NG” is transmitted to the issuing IC card 3A (step A11). In addition, when it is determined that the authentication result is “NG” in Step A3, or when the password verification response is determined as “NG” or “None” in Step A5, “ NG "processing end notification.
[0029]
After issuing the data write response in step B9, the issuing IC card 3A determines whether an “OK” or “NG” process end notification has been sent from the issued data write processing unit 21 (step B10). ), The processing ends normally when the “OK” processing end notification is sent. The issuing IC card 3A is read / written when a processing end notification “NG” is sent from the issuing data write processing unit 21 or when a processing end notification is not sent within a predetermined time. The write function is closed (step B11), and the process ends with the issue data not being written. Even when it is determined in step B3 that the authentication result is “NG”, or in the case where password verification is determined as “NG” in step B6, the read / write function blocking process shown in step B11 above. Execute.
[0030]
The issuance processing office 13 performs the issuance data writing process for the issuance IC card 3A as described above, and returns the issuance IC card 3A in which the issuance data is correctly written to the user 11.
[0031]
The user 11 performs an on-board unit issuance process using the issuance IC card 3A returned from the issuance processing office 13.
Hereinafter, the details of the on-board unit issuance process by the issuing IC card 3A will be described with reference to the flowchart shown in 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 attaches the issuing IC card 3A returned from the issuing processing office 13 to 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 process of the vehicle-mounted device 2 is executed, and power is supplied from the vehicle-mounted device 2 to the issuing IC card 3A to execute the initial process (step D1). At this time, the issuing IC card 3A is in a state in which the read / write function closed state is released.
[0032]
Next, the issuing IC card 3A and the vehicle-mounted device 2 perform authentication operations with each other and confirm that they are normal media (step C2, step D2). Further, the issuing IC card 3A reads the vehicle-mounted device ID from the vehicle-mounted device 2, and confirms whether or not the vehicle-mounted device ID matches the issue destination vehicle-mounted device ID recorded in the issuing IC card 3A.
[0033]
Thereafter, the issuing IC card 3A determines the authentication result (step C3), and if the authentication result is “OK” and the IDs match, the issued issuance data is transmitted to the vehicle-mounted device 2 ( Step C4). If the authentication result is “NG” or the IDs do not match, the process is terminated as it is, and it is prohibited to transfer the information in the issuing IC card 3A to the outside.
[0034]
On the other hand, the in-vehicle device 2 determines whether or not the authentication result is “OK” when performing the mutual authentication in step D2 (step D3). The issued data that is sent is received (step D4), and the cipher is decrypted and stored in the internal memory (step D5). Then, the result of writing this data is judged. If “NG”, the process returns to step D4 to retry. When the set number of retries for issuing issuance data is exceeded, an “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 data writing in step D6 is “OK”, a notice of “OK” processing completion is sent to the issuing IC card 3A.
[0035]
The issuance IC card 3A determines whether or not a processing end notification has been sent from the vehicle-mounted device 2 after transmitting the issuance data in step C4. When the “OK” processing end notification is received, the read / write function Occlude. 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 thawing procedure known only by the issuing processing office 13 is performed. However, the issuing IC card 3A holds only the minimum external data reading function necessary for performing the decompression procedure. Then, the issuing IC card 3A notifies the vehicle-mounted device 2 that the read / write function has been closed, and normally ends the issuing process. In step C5, when an “NG” processing end notification is received from the vehicle-mounted device 2, or when a processing end notification is not sent within a predetermined time, the issuing process is not completed. finish.
[0036]
The vehicle-mounted device 2 determines whether or not a read / write function blockage notification has been sent from the issuing IC card 3A (step D9). Completes normally. If the read / write function blockage notification is “NG” from the issuing IC card 3A, or if the read / write function blockage notification is not sent within a predetermined time, the processing is performed in an unissued state. finish.
[0037]
Thus, the issuing process for the vehicle-mounted device 2 is completed, and the issuing IC card 3A is taken out from the vehicle-mounted device 2. An on-board device 2 that has completed the above issuance processing can be subjected to automatic toll collection processing at a toll gate on a toll road by mounting an IC card for fee settlement.
[0038]
In the above embodiment, when the user 11 purchases the vehicle-mounted device 2 from the retail store 12, the IC card 3A for issue and the application form are acquired, and the IC card 3A for issue and the application form are issued to the issuance processing office 13. However, the issue processing of the vehicle-mounted device 2 may be performed by the following method.
[0039]
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 acquired, and necessary items are described in this application form and sent to the issued data writing processing unit 21. The issuance processing office 13 writes the issuance data on the issuance IC card 3A based on the items described in the application form sent from the user 11, and sends it to the user 11.
[0040]
When the above method is used, the user 11 only has to send the application form to the issuance processing office 13, and it is not necessary to send the issuing IC card 3A. Application becomes easy.
[0041]
【The invention's effect】
As described above in detail, according to the present invention, when a user purchases a vehicle-mounted device from a retail store, the user obtains an IC card for issuance and an application form, and sends the IC card for issuance and the application form to an issuance processing office. Since the issuance data is recorded on the issuing IC card, the burden on the user can be remarkably reduced. In other words, since the IC card is highly portable, it can be easily sent to an issuance processing office using mail or other means. 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, so that the burden is not so much.
[0042]
In addition, an IC card for issuance is prepared in advance in the issuance processing office, and the user sends only the application form to the issuance processing office. When issuance data is written in the IC card for use and sent to the user, the burden on the user can be further reduced.
