Abstract
Systems, apparatuses, and methods for securing wireless communication using an acoustic signal are described. In one method involving a first and second device, the second device generates, when connecting to the first device, connection initiation information including key information for secure communication, converts the connection initiation information to an acoustic signal, and transmits the acoustic signal to the first device through an acoustic communication channel. Then the second device monitors a radio wireless channel, which is secured using the key information for secure communication, to determine whether a valid response is received from the first device and, upon receipt of the valid response, discontinues transmission of the acoustic signal and begins communicating with the first device securely on the radio wireless channel.
