Abstract
In automatic driving or the like, it is necessary to prevent an attacker from performing message transmission by impersonating a vehicle. If it is determined that a history of acquired behavioral information of own vehicle does not match vehicle behavior, a message indicating that communication between the own vehicle and a surrounding vehicle is stopped is transmitted to the surrounding vehicle.
Claims12
A wireless communication apparatus comprising:
- a processor to execute a program;
- and
- a memory to store the program which, when executed by the processor, causes the processor to perform operations comprising:
- acquiring behavioral information of a vehicle while the vehicle is in a driving state, the behavioral information representing a behavior of the wireless communication apparatus while the wireless communication apparatus is mounted in this vehicle;
- storing the behavioral information in a behavioral information storage;
- based on receiving a message transmission request, determining whether the behavioral information stored in the behavioral information storage represents a vehicle behavior being currently acquired;
- based on a result of the determining indicating that the behavioral information represents the vehicle behavior, controlling a transmitter of the wireless communication apparatus to perform a message transmission to another vehicle;
- and
- based on the result of the determining indicating that the behavioral information, does not represent the vehicle behavior, controlling the transmitter to transmit to the another vehicle a stop transmission message indicating that the message transmission is not being performed and to transmit, to a communication manager, a message indicating that the vehicle is impersonated.

A wireless communication apparatus comprising:
- a processor to execute a program;
- and
- a memory to store the program which, when executed by the processor, causes the processor to perform operations comprising:
- acquiring behavioral information of a vehicle, the behavioral information representing a behavior of the wireless communication apparatus while the wireless communication apparatus is mounted in this vehicle;
- storing the behavioral information of the vehicle in a behavioral information storage;
- acquiring behavioral information of another vehicle;
- storing the behavioral information of the another vehicle in an another-vehicle behavioral information storage;
- based on receiving, a message transmission request, determining whether the behavioral information of the vehicle represents a vehicle behavior by comparing the behavioral information of the vehicle with the behavioral information of the another vehicle;
- performing by a transmitter of the wireless communication apparatus, a message transmission to the another vehicle based on a result of the determining that the behavioral information of the vehicle represents the vehicle behavior and based on the message transmission request;
- and
- based on the result of the determining indicating that the behavioral information of the vehicle does not represent the vehicle behavior, controlling the transmitter to transmit to the another vehicle a stop transmission message indicating that the message transmission is not being performed and to transmit, to a communication manager, a message indicating that the vehicle is impersonated.

A wireless communication method between a vehicle and another vehicle, the wireless communication method comprising:
- acquiring, by the vehicle, behavioral information of the vehicle while the vehicle is in a driving state, the behavioral information representing a behavior of a wireless communication apparatus while the wireless communication apparatus is mounted in this vehicle;
- storing the acquired behavioral information;
- based on a message transmission request, determining whether the stored behavioral information represents a vehicle behavior being currently acquired;
- based on the determining that the behavioral information represents the vehicle behavior, performing a message transmission to the another vehicle;
- and
- based on the determining that the behavioral information does not represent the vehicle behavior, transmitting, to the another vehicle, a stop transmission message indicating that the message transmission is not being performed and transmitting, to a communication manager, a message indicating that the vehicle is impersonated.

A wireless communication method between a vehicle and another vehicle, the wireless communication method comprising:
- acquiring, by the vehicle, behavioral information of the vehicle, the behavioral information representing a behavior of a wireless communication apparatus while the wireless communication apparatus is mounted in this vehicle;
- storing the acquired behavioral information of the vehicle;
- acquiring behavioral information of the another vehicle from the another vehicle;
- storing the acquired behavioral information of the another vehicle;
- based on receiving a message transmission request, determining whether the behavioral information of the vehicle represents a vehicle behavior by comparing the behavioral information of the vehicle with the behavioral information of the another vehicle;
- and
- based on the determining that the behavioral information of the vehicle does not represent the vehicle behavior, transmitting, to the another vehicle, a stop transmission message indicating that a message transmission is not being performed and transmitting, to a communication manager, a message indicating that the vehicle is impersonated.
