Abstract

        Despite providing a wired communications infrastructure, power line communication (PLC) is broadcast in nature due to the shared channel usage by all intended users. This introduces privacy concerns for confidential communication in multi-user environments, such as in smartmeter data transmission using PLC, where data packets are exposed to potential eavesdroppers. In this paper, we propose, for the first time, a physical layer security (PLS) solution for multiple-input multipleoutput (MIMO) PLC systems using in-band full-duplex (IBFD) technology. IBFD allows PLC receivers to jam the operating frequency band while also receiving intended data packets at the same time. In this respect, we optimize the information and jamming transmission strategies, together with power allocation over different sub-carriers, with the goal of maximizing the secrecy energy efficiency. Our numerical results illustrate the multi-fold increase in secrecy rates that we obtain using an IBFD-based PLS technique over a half-duplex operation without jamming.
