Abstract
A method and apparatus for generating physical layer security keys is provided. Channel impulse response (CIR) measurements are recorded. Each CIR measurement is associated with a time-stamp. Where possible, the time-stamps are paired with time-stamps that are associated with another plurality of CIR measurements. The CIR data associated with the paired time-stamps is aggregated. Each of the aggregated CIR measurements is aligned, and at least one CIR measurement is selected for use in secret key generation.
