We propose to recover the energy penalty of the physical-layer security solutions without compromising security performance. This ambitious vision becomes achievable when a co-design approach, involving transmitter architecture, digital baseband, RF frontend and signal waveforms, is employed. This will require major innovations that currently lie beyond state-of-the-art, which include (a) system architecture- and modulation-aware AN synthesis; (b) non-linear power amplifier-friendly AN synthesis; (c) digital/analogue hybrid modulation and precoding security scheme; and (d) system-level demonstration of physical-layer security solutions. We are not aware of any other research programme that has systematically studied hardware-aware optimum signal waveform synthesis for energy efficient physical-layer wireless security systems.
