Power line communication (PLC) has enabled many smart grid applications and functionalities over the past few years. Secure communications over such links however remain a crucial aspect for further development. Due to their shared nature, akin to wireless, PLC channels can benefit from many wireless-type security techniques, including physical layer security. To this end, and in contrast to existing...
Power-line communications (PLC) have enabled many smart grid applications over the past years. Secure communications over such channels, however, remains a crucial aspect for the successful realization of smart grids. Many techniques have been proposed in the literature to achieve this and the most recent of which is the adoption of physical layer security for PLC systems. Unlike the existing work,...
In this paper, we analyze the secrecy capacity of a multiple-input multiple-out (MIMO) half duplex amplify-and-forward (AF) relay network in the presence of one passive eavesdropper. Zero forcing (ZF) processing is utilized at various locations to improve the capacity when the eavesdropper is equipped with a single antenna. The impact of the proposed ZF-based technique on the secrecy capacity is investigated...
