1. A method, performed by an electronic device, of authenticating an external device, the method comprising:
transmitting a first signal through a transceiver, wherein:
the first signal is distorted by a user's gesture,
the first signal distorted by the user's gesture is received by the external device as a first distorted signal, and
the external device copies the received first distorted signal to generate a second distorted signal and transmits the second distorted signal to the electronic device;
acquiring, while the first signal is transmitted, information about the user's gesture through a gesture sensor;
acquiring a distortion pattern corresponding to the information about the user's gesture;
receiving the second distorted signal from the external device;
determining a correlation between the second distorted signal and the distortion pattern corresponding to a type of the user's gesture; and
authenticating the external device based on a proximity between the external device and the electronic device determined based on the correlation.
