Abstract

The growing concern of secure communication becomes more challenging when encountering a hybrid Full-duplex (FD) attacker possessing the dual capability to perform eavesdropping and jamming simultaneously. To analyze secrecy outage performance in the presence of such a potential attacker, the proposed work assumes complete information of the legitimate link only. It considers unavailability of complete information of all the ungoverned communication links including eavesdropping, jamming and self-interference link of attacker. FD operation is associated with the problem of imperfect self-interference cancellation. Our proposed analysis considers residual self-interference at the attacker's end in its modelling. The closed-form expressions have been obtained for secrecy outage probability under generalized as well as special cases. The results obtained facilitate in investigating the impact of fading under FD attack and provide important insights about source power, jamming power, attacker's location. Approximate closed-form results also help in reducing computation time by more than 55%.
