N2 - Energy harvesting relaying is predicted to play a pivotal role in large-scale energy constrained networks. This letter evaluates the secrecy performance of a system that employs a three-step two-way decode-and-forward relay with the energy harvesting capability. More specifically, we derive a closed-form expression for the eavesdropping probability when the main and wiretap links experience independent κ-μ shadowed fading. We evaluate the impact of the fading parameters, and the power splitting factor at the relay, on the secrecy performance. Our results indicate that for a small relay reception interval, secrecy can be enhanced by allocating more power for information decoding. Numerical results are provided to validate the derived results.
