1. A communication device comprising:
a Bluetooth Low Energy (BLE) communication section configured to perform BLE communication with another communication device different from the communication device and to obtain key information, the BLE communication being wireless communication conforming to BLE communication standards;
an Ultra Wide Band (UWB) communication section configured to perform UWB communication with the other communication device, the UWB communication being wireless communication conforming to UWB communication standards; and
a control section configured to control the BLE communication of the BLE communication section and the UWB communication of the UWB communication section,
wherein the control section performs control to start the UWB communication based on a response signal transmitted by one of the BLE communication section and the other communication device as a response to a request signal transmitted by other one of the BLE communication section and the other communication device during the BLE communication, and performs control to trigger the UWB communication to perform encrypted communication using the key information obtained via the BLE communication.
