In this paper, we analyze the secrecy performance of single-input multiple-output (SIMO) relay systems over κ-μ shadowed fading channels.Based on considering relay model employing decode-and-forward (DF) protocol, two security evaluation metrics, namely, secure outage probability (SOP) and probability of strictly positive secrecy capacity (SPSC) are studied, for which closed-form analytical expressions are derived.In addition, Monte Carlo results prove the validity of the theoretical derivation.The simulation results confirm that the factors that enhance the security include large ratio of ( ) ,
