Abstract
A method includes broadcasting, by a powered wireless device, a survey request frame to a plurality of ambient (AMP) devices that harvest environmental energy, wherein the survey request frame comprises a unique public key to be used by each AMP device, of the plurality of AMP devices, to generate a survey response frame. The method includes using, within the survey request frame, a first random address as a source media access control (MAC) address and one of a broadcast address or a group address as a destination MAC address. The method includes determining, from each respective survey response frame, whether a corresponding AMP device of the plurality of AMP devices is accessible from which to securely obtain data.
