Examples are disclosed that relate to improving security of radio frequency (RF) backscattered communication. In one example, a RF device includes a primary RF signal receiver, a secondary signal receiver, a signal mixer, and a transmitter. The primary RF signal receiver is configured to receive a RF carrier signal sent from a base station. The secondary signal receiver is configured to receive a masking signal from the base station. The signal mixer is configured to generate a response signal based at least on the RF carrier signal and generate a mixed signal by mixing the response signal and the masking signal. The transmitter is configured to broadcast the mixed signal, via backscattering, as a masked backscattered signal.
