Recently, Geng et al. have shown that from the perspective of generalized degrees of freedom (GDoF), power control and treating interference as noise (TIN) is optimal for a broad class of Gaussian interference channels. In this work, we show that for TIN-optimal interference channels identified by Geng et al., secrecy constraints on unintended messages incur no GDoF penalty, which leads us to a secure...
We consider 2-user symmetric interference channels with confidential messages. For the linear deterministic model of this channel, we develop inner and outer bounds for the symmetric secure rate, which are shown to match and characterize the symmetric secure capacity for a wide range of channel parameters. For the achievability, we present a cooperative jamming scheme based on interference alignment...
