Authentication control device and authentication control method

1. An authentication control device configured to be mounted over a mobile object, the authentication control device comprising:

a communication circuit;

one or more memories; and

one or more processors coupled to the one or more memories, at least any one of the one or more processor being configured to:

perform storing of a first authentication key received from a server device in any of the one or more memories, the first authentication key being a key relating to a second authentication key stored in a terminal of a user;

in response to a signal indicating that the mobile object arrives at a predetermined location, activate the communication circuit from deactivated state;

in response to receiving of a request signal from the terminal through the activated communication circuit, cause the activated communication circuit to transmit first information to the terminal;

in response to transmitting of the first information, receive second information from the terminal through the activated communication circuit, the second information being the first information encoded in accordance with the second authentication key by the terminal configured to receive the first information from the authentication control device to generate the second information by encoding the received first information based on the second authentication key;

in response to receiving of the second information, decode the received second information by the stored first authentication key; and

execute an authentication process of the user by using the first information and information acquired by the decoding of the second information.

2. The authentication control device according to claim 1 , wherein

the storing of the first authentication key includes storing first identification information for identifying the terminal, the first identification information being received from the server device, and

the receiving of the first information includes receiving other first identification information from the terminal.

3. The authentication control device according to claim 1 , wherein

the one or more processors are configured to

generate second identification information for identifying the authentication control device,

transmit the second identification information to the terminal via the server device, and

in the communication between the authentication control device and the terminal in the state where the authentication control device is uncommunicable with the server device, transmit other second identification information to the terminal.

4. The authentication control device according to claim 1 , wherein the authentication control device includes a drive device for moving.

5. The authentication control device according to claim 1 , wherein

the one or more processors are configured to, after the authentication process, when the authentication control device is communicable with the server device, transmit a result of the authentication process to the server device.

6. The authentication control device according to claim 1 , wherein

the authentication process is executed by a first processor among the one or more processors, and

the first authentication key is received by a second processor among the one or more processors.

7. The authentication control device according to claim 6 , wherein

the first processor is detachable from the authentication control device.

8. An authentication control method executed by an authentication control device configured to be mounted over a mobile object, the authentication control method comprising:

storing a first authentication key received from a server device in the authentication control device, the first authentication key being a key relating to a second authentication key stored in a terminal of a user; and

in response to a signal indicating that the mobile object arrives at a predetermined location, activating a communication circuit of the authentication control device from deactivated state;

in response to receiving of a request signal from the terminal through the activated communication circuit, causing the activated communication circuit to transmit first information to the terminal;

in response to transmitting of the first information, receiving second information from the terminal through the communication circuit, the second information being the first information encoded in accordance with the second authentication key by the terminal configured to receive the first information from the authentication control device to generate the second information by encoding the received first information based on the second authentication key;

in response to receiving of the second information, decoding the received second information by the stored first authentication key; and

executing an authentication process of the user by using the first information and information acquired by the decoding of the second information.

9. The authentication control method according to claim 8 , wherein

the storing of the first authentication key includes storing first identification information for identifying the terminal, the first identification information being received from the server device; and

the receiving of the first information includes receiving other first identification information from the terminal.

10. The authentication control method according to claim 8 , comprising:

generating second identification information for identifying the authentication control device;

transmitting the second identification information to the terminal via the server device; and

in the communication between the authentication control device and the terminal in the state where the authentication control device is uncommunicable with the server device, transmitting other second identification information to the terminal.

11. The authentication control method according to claim 8 , wherein the authentication control device includes a drive device for moving.

12. The authentication control method according to claim 8 , comprising:

after the authentication process, when the authentication control device is communicable with the server device, transmitting a result of the authentication process to the server device.

13. The authentication control method according to claim 8 , wherein

the authentication control device includes a first processor and a second processor,

the authentication process is executed by the first processor, and

the first authentication key is received by the second processor.

14. The authentication control method according to claim 13 , wherein

the first processor is detachable from the authentication control device.

15. A non-transitory computer-readable medium storing a program for causing an authentication control device to perform processing, the authentication control device being configured to be mounted over a mobile object, the processing comprising:

storing a first authentication key received from a server device in the authentication control device, the first authentication key being a key relating to a second authentication key stored in a terminal of a user; and

in response to a signal indicating that the mobile object arrives at a predetermined location, activating a communication circuit of the authentication control device from deactivated state;

in response to receiving of a request signal from the terminal through the activated communication circuit, causing the activated communication circuit to transmit first information to the terminal;

in response to transmitting of the first information, receiving second information from the terminal through the activated communication circuit, the second information being the first information encoded in accordance with the second authentication key by the terminal configured to receive the first information from the authentication control device to generate the second information by encoding the received first information based on the second authentication key;

in response to receiving of the second information, decoding the received second information by the stored first authentication key; and

executing an authentication process of the user by using the first information and information acquired by the decoding of the second information.
