Abstract
Generally, this disclosure provides systems, devices, methods and computer readable media for wireless power transfer with improved device identification and signaling security. A Power Receiving Unit (PRU) may include a receive resonator module to receive power from a Power Transmitting Unit (PTU) over an inductive resonant coupling link. The power may be modulated to provide signaling between the PRU and the PTU over the resonant coupling link. The PRU may also include a signaling link communication module to provide a second type of signaling between the PRU and the PTU over a wireless communication link. The PRU may further include a controller module to receive a random number, generated by the PTU, over the resonant coupling link; calculate an encoded response based on the random number and on an identifier of the PRU; and transmit the encoded response to the PTU over the wireless communication link, for verification by the PTU.
