Effective Secrecy Throughput in PLC Systems Threatened by a Wireless Eavesdropper: A Practical Perspective

This paper advances the investigation of physical layer security of broadband and indoor power line communication (PLC) system when a malicious wireless communication (WLC) device tries to eavesdrop upon private messages exchanged between two PLC devices. To do so, numerical results related to the effective secrecy throughput and the corresponding wiretap code rates for distinct positions of the malicious WLC device are provided for three different frequency bands, 1.7-30 MHz, 1.7-50 MHz, and 1.7-86 MHz under the power masks defined by the IEEE 1901 13-29 and ITU-T G.9964 standards.
