Abstract

Abstract

Physical layer secret key capacity is affected by such factors as additive noise, the time difference of channel sampling, terminals moving speed, sampling period, and the number of samples, whose effects on the physical layer secret key capacity are analyzed quantitatively using the single-input single-output wireless channel over the uniform scattering environment. Specifically, a closed-form solution to the secret key capacity is derived to determine the constraints on the optimal sampling period. Analysis and simulation results reveal that the results can also be applied to the nonuniform scattering environment. Furthermore, the feasibility to utilize the physical layer secret key extraction techniques in the mobile communication systems is verified.
