  • System and method for securing backscatter wireless communication
    Patent number: 9672394
    Abstract: A system and method for securing backscatter communication. In one embodiment, a backscatter communication system includes a reader. The reader is configured to receive backscatter transmissions. The reader includes a transmitter configured to emit a radio frequency signal to induce backscatter communication. The transmitter includes a continuous wave (CW) carrier signal generator and a noise signal generator. The CW carrier signal generator produces a CW carrier signal. The noise signal generator generates a noise signal. The transmitter is configured to combine the CW carrier signal and the noise signal, and to transmit the combined signal to induce backscatter communication.
