Abstract:
Embodiments of a near-field communication (NFC) system and method for private near-field communication are generally described herein. In some embodiments, a resonance-coupled channel is masked with a random channel-masking signal. The channel-masking signal may be scaled based on near-field channel conditions. Signals received through the channel may be unmasked with the scaled channel-masking signal to determine data that may have been conveyed by an NFC transmitting device by affecting the impedance of the resonance-coupled channel. In some embodiments, a reference signal may be scrambled with a mask to generate the channel-masking signal. The mask may include at least one of a random symbol mask, an amplitude mask and a phase mask. For additional privacy, the mask may include a random symbol mask and at least one of an amplitude mask and a phase mask.
