Artificial noise injection; Secrecy outage probability; Zero-outage secrecy capacity.


A proposed artificial noise (AN) injection strategy is considered in amplify-and-forward (AF) relaying systems. The limit of secrecy rate, hence the resulting zero-outage secrecy throughput, is determined subject to guarantee zero secrecy outage toward any powerful eavesdropper. The results show that the proposed simple strategy can achieve zero secrecy outage, which cannot be achieved in literature, and that it is easy to apply in wireless networks. The results also show an important finding: increasing throughput against increasing transmit power in secrecy.
