In this study, the authors investigate the physical layer security performance over Rayleigh fading channels in the presence of impulsive noise, as encountered, for instance in smart grid environments. For this scheme, secrecy performance metrics are considered with and without destination assisted jamming at the eavesdropper's side. Specifically, they derive analytical expressions for the secrecy outage probability (SOP), at the legitimate receiver. Finally, numerical results are provided to verify the accuracy of the authors' derivations. From the obtained results, it is verified that the SOP, without destination assisted jamming, is flooring at high signal‐to‐noise‐ratio values and that it can be significantly improved with the use of jamming.
