Description:

Key reconciliation techniques are employed to discard the effect of uncorrelated noise present at the communicating nodes of a reciprocal channel. Under a direct line-of-sight scenario, to randomize the channel, one of the communicating nodes shall be equipped with a RECAP antenna. The Linde-Buzo-Gray vector quantization is employed to the measured data, to support key generation. To eliminate the effect of statistically independent noise, a guard-band key reconciliation technique is adopted along the Voronoi thresholds. The constructed guard-band regions mark the validity of the respective keys, where all keys lying within the guard-band regions are discarded. Thus, the system generates only valid keys lying outside the guard-band region, to ensure less communication errors.
