<Operation of information processing system 10>
Next, pairing processing of the information processing system 10 will be described with reference to FIGS. 3 and 4. FIG. The flow of pairing processing executed by the information processing device 2 will be described with reference to the flowchart shown in FIG. The flow of pairing processing executed by the information processing terminal 3 will be described with reference to the flowchart shown in FIG. Hereinafter, the pairing process performed by the information processing device 2 will be referred to as the first pairing process, and the pairing process performed by the information processing terminal 3 will be referred to as the second pairing process. Also, S indicates a step in the flow chart. As a premise, the information processing terminal 3 is in a state where the program 36 is running.

- First pairing process The first pairing process is a process that is executed periodically at predetermined time intervals when the information processing device 2 is activated and after the activation.

As shown in FIG. 3, the information processing device 2 determines whether or not the short-range wireless communication radio waves transmitted by the information processing terminal 3 have been received (S10). The information processing device 2 (1) does not receive radio waves for short-range wireless communication (S10: NO), or (2) receives radio waves for short-range wireless communication (S10: YES), but receives If the first storage unit 23 does not have the same first connection information 26 as the information contained in the received radio wave (S20: NO), a process for displaying the two-dimensional code 25 is executed (S30 to S50). . When (1) the radio wave of the short-range wireless communication is not received and (2) the radio wave of the short-range wireless communication is received, but the same first connection information 26 as the information included in the received radio wave Hereinafter, the case where the first storage unit 23 does not have the two-dimensional code display condition is referred to as the case where the two-dimensional code display condition is established. That is, when the two-dimensional code display condition is satisfied, the information processing device 2 generates a public key (S30), and generates the two-dimensional code 25 including the address of the information processing device 2 and the generated public key (S40 ), the generated two-dimensional code 25 is displayed on the display device of the first input/output unit 22 (S50).

Here, (1) the case where the short-range wireless communication radio wave is not received is, for example, the case where the short-range wireless function of the information processing terminal 3 carried by the user is stopped inside the vehicle 1. is mentioned. (2) A case where the first storage unit 23 does not have the same first connection information 26 as the information included in the received radio wave although the radio wave of the short-range wireless communication is received means that the user is in the vehicle. 1, the short-range wireless function of the information processing terminal 3 carried in the vehicle 1 is activated, and the information processing terminal 3 is carried in the vehicle 1 for the first time.

After displaying the two-dimensional code 25, the information processing device 2 determines whether or not the public key generated by the information processing terminal 3 has been received, based on the short-range wireless communication radio waves transmitted by the information processing terminal 3. Determine (S60). The short-range wireless communication radio waves transmitted by the information processing terminal 3 that has read the two-dimensional code 25 include the address of the information processing terminal 3 and the public key generated by the information processing terminal 3 .

When the information processing device 2 receives the public key generated by the information processing terminal 3 from the information processing terminal 3 (S60: YES), the information processing device 2 executes authentication processing (S70).

Here, in the authentication process, the public keys generated by the information processing device 2 and the information processing terminal 3 are exchanged, and the public key generated by itself is multiplied by the public key generated by the communication partner. This is processing for verifying whether or not the calculated values match. Specifically, information processing device 2 transmits the public key generated by information processing device 2 to information processing terminal 3, and information processing terminal 3 transmits the public key generated by information processing terminal 3 to the information processing device. 2. Next, information processing device 2 multiplies the public key generated by itself by the public key transmitted from information processing terminal 3 to generate a first calculated value X1, and converts the generated first calculated value X1 to Send to the information processing terminal 3 . Similarly, the information processing terminal 3 multiplies the public key generated by itself and the public key transmitted from the information processing device 2 to generate the second calculated value X2. X2 is transmitted to the information processing device 2 . Finally, the information processing device 2 and the information processing terminal 3 respectively verify whether or not the first calculated value X1 and the second calculated value X2 match, and if they match, it is assumed that the authentication has succeeded. judge. If the authentication is successful, the first calculated value X1 and the second calculated value X2 are treated as secret keys of the information processing device 2 and the information processing terminal 3 . After that, the information processing device 2 and the information processing terminal 3 can establish a communication connection without performing a new pairing process by mutually holding this secret key.

When the authentication process is successful (S80: YES), the information processing device 2 stores the address of the information processing terminal 3 and the public key generated by the information processing terminal 3 as the first connection information 26 in the first storage unit 23. store (S90), and establish a communication connection with the information processing terminal 3 based on the first connection information 26 (S100). As a result, the information processing device 2 does not need to perform pairing processing with the information processing terminal 3 from the next time onwards.

On the other hand, when the authentication process fails (S80: NO), the information processing device 2 ends the first pairing process without performing connection setting for short-range wireless communication with the information processing terminal 3. FIG.

Further, when the two-dimensional code display condition is not satisfied, that is, when the information processing device 2 receives the radio waves of the short-range wireless communication (S10: YES), and the information contained in the received radio waves is the same as the first connection If the information 26 is stored in the first storage unit 23 (S20: YES), communication connection is established with the information processing terminal 3 based on the first connection information 26 stored in the first storage unit 23. (S110). In this case, since the other party of communication is the information processing terminal 3 with which the information processing device 2 has a communication connection in the past, the information processing device 2 does not need to newly perform the authentication process to reset the first connection information 26 .

Second Pairing Processing The second pairing processing is processing when the information processing terminal 3 reads the two-dimensional code 25 displayed on the information processing device 2, as shown in FIG. If the information processing device 2 does not display the two-dimensional code 25 and the information processing terminal 3 does not need to read the two-dimensional code 25, the information processing terminal 3 has already established a communication connection with the information processing device 2. Since the short-range wireless communication function is also activated, the information processing terminal 3 does not perform pairing processing.

When the information processing terminal 3 uses a camera to image the two-dimensional code 25 displayed on the information processing device 2 and reads the two-dimensional code 25 (S210), the information contained in the read two-dimensional code 25 is The address of the processing device 2 and the public key generated by the information processing device 2 are obtained (S220).

If the information processing terminal 3 does not have the second connection information 35 identical to the address of the information processing device 2 acquired from the two-dimensional code 25 and the public key generated by the information processing device 2 in the second storage unit 33, (S230: NO) activates the short-range wireless communication function. The information processing terminal 3 activates the short-range wireless communication function to transmit radio waves for short-range wireless communication (S240), generates a public key (S250), and stores the address of the information processing terminal 3 and the generated public key. The key is transmitted to the information processing device 2 (S260), and authentication processing is executed (S270). The authentication process is as described in the first pairing process.

When the authentication process is successful (S280: YES), the information processing terminal 3 stores the address of the information processing device 2 and the public key generated by the information processing device 2 as the second connection information 35 in the second storage unit 33. The information is stored (S290), and communication connection is established with the information processing device 2 based on the second connection information 35 (S300). This eliminates the need for the information processing terminal 3 to perform pairing processing with the information processing device 2 from the next time onwards.

On the other hand, when the authentication process fails (S280: NO), the information processing terminal 3 ends the second pairing process without performing connection setting for short-range wireless communication with the information processing device 2. FIG.

The information processing terminal 3 also has the second connection information 35 identical to the address of the information processing device 2 obtained from the two-dimensional code 25 and the public key generated by the information processing device 2 in the second storage unit 33 . If so (S230: YES), the short-range wireless communication radio wave is transmitted by activating the short-range wireless communication function (S310). The information processing terminal 3 establishes communication connection with the information processing device 2 based on the second connection information 35 stored in the second storage unit 33 (S320). In this case, the information processing terminal 3 does not need to perform a new authentication process to reset the second connection information because the communication partner is the information processing apparatus 2 with which communication has been connected in the past.

As described above, in the information processing system 10, when the information processing device 2 displays the two-dimensional code 25, the information processing terminal 3 automatically performs the pairing process with the information processing device 2 only by reading the two-dimensional code 25. Done, you can set up your communication connection. Therefore, according to the information processing system 10, it is possible to easily set the communication connection between the information processing terminal 3 and the information processing device 2 by a relatively simple method. Further, according to the information processing system 10, the use of the communication connection between the information processing terminal 3 and the information processing device 2 can be promoted.

That is, in the information processing system 10, conventionally, a complicated operation procedure that the user has to perform in setting the short-range wireless communication, for example, the user opens a setting screen related to network connection of the information processing terminal 3 and performs the short-range wireless communication. No action is required to activate communication settings. In the information processing system 10, the user opens the menu setting screen of the information processing device 2, searches for the information processing terminal 3 in which the short-range wireless communication setting is active, and selects the information processing terminal 3. , there is no need to perform a series of pairing operations such as confirming the PIN code and password issued by the information processing device 2 on the information processing terminal 3 . As a result, in the information processing system 10, it is possible to reduce the operation burden on the user in the pairing process.

Further, in the information processing system 10, the two-dimensional code 25 is displayed only when the two-dimensional code display condition is satisfied, that is, when the information processing device 2 cannot detect the communication connection with the information processing terminal 3. It is configured to prompt communication connections between For this reason, the user only has to read the two-dimensional code 25 when necessary, so that the user does not feel troublesome about the work.
