Abstract
In this paper, we analyze the secrecy outage probability (SOP) of a two-way cooperative communication network aided by an energy harvesting untrusted half-duplex amplify and forward relay which conveys information between two legitimate users. The whole communication completes in two time slots. The relay receives signal from both users simultaneously in the first time slot meanwhile it harvests energy based on power splitting ratio scheme. In the second time slot, the relay amplifies and forwards the signal to both users as well as it eavesdrops the message. The relay works as an eavesdropper where signal from one user acts as a jamming signal for the signal of other user. An analytical expression of SOP involving a numerical integration has been derived in single integration form. We verify our analytical results with the simulated results.
