Authentication system, mobile device, processing device, and non-transitory computer-readable medium

A control device configured to control an operation of a controlled device, comprising:

• a processor configured to cause a communication device to form a wireless communication area at least outside of a cabin arranged to be opened/closed by an opening/closing body, and configured to determine whether an authentication processing for authenticating a mobile device adapted to be carried by a user located in the wireless communication area with radio waves is succeeded;
• and
• a reception interface configured to receive, from the mobile device with the radio waves, a magnetism detection signal indicating that the mobile device detects a specific magnetism,
• wherein the processor is configured to control the operation of the controlled device in a case where the reception interface receives the magnetism detection signal and it is determined that the authentication processing is succeeded.

A non-transitory computer-readable medium having recorded a computer program adapted to be executed by a processor installed in a control device configured to control an operation of a controlled device, and configured to, when executed, cause the control device to:

• cause a communication device to form a wireless communication area at least outside of a cabin arranged to be opened/closed by an opening/closing body;
• determine whether an authentication processing for authenticating a mobile device adapted to be carried by a user located in the wireless communication area with radio waves is succeeded;
• determine whether a magnetism detection signal indicating that the mobile device detects a specific magnetism is received from the mobile device with the radio waves;
• and
• control the operation of the controlled device in a case where the reception interface receives the magnetism detection signal and it is determined that the authentication processing is succeeded.

A non-transitory computer-readable medium having recorded a computer program adapted to be executed by a processor installed in a mobile device adapted to be carried by a user, and configured to, when executed, cause the mobile device to:

• transmit an authentication signal including information required by an authentication processing for authenticating the mobile device to a communication device configured to form a wireless communication area at least outside of a cabin arranged to be opened/closed by an opening/closing body;
• cause a magnetic sensor to detect magnetism formed at least outside of the cabin;
• determine whether a specific magnetism is detected by the magnetic sensor;
• and
• transmit a magnetism detection signal to the communication device in a case where it is determined that the specific magnetism is detected.
