Physical-Layer Security: Does it Work in a Real Environment?
This work addresses security challenges in wireless communication for practical applications, but it is incremental as it applies existing methods to new data.
The paper tackles the problem of implementing physical-layer security in real indoor environments by using channel sounding measurements to assess secrecy capacity and test various Reed-Muller wiretap codes, resulting in a three-point design process for deployment.
This paper applies channel sounding measurements to enable physical-layer security coding. The channel measurements were acquired in an indoor environment and used to assess the secrecy capacity as a function of physical location. A variety of Reed-Muller wiretap codes were applied to the channel measurements to determine the most effective code for the environment. The results suggest that deploying physical-layer security coding is a three-point design process, where channel sounding data guides 1) the physical placement of the antennas, 2) the power settings of the transmitter, and 3) the selection of wiretap coding.
