Secrecy performance is one of the most crucial and interesting aspects of physical layer security (PLS) that has been analyzed in the past decades. Reconfigurable intelligent surface (RIS) is a cost-effective component to enhance the secrecy performance of wireless communication systems. In this letter, we assume that an RIS is located between the legitimate source and the destination, existing an eavesdropper overhearing the radios transmitted from the source and the RIS. Based on the assumption, we derive the probability density function (PDF) and cumulative distribution function (CDF) of the received signal-to-noise ratio (SNR). In addition, we deduce a converged approximation of the secrecy outage probability (SOP). Finally, simulation results verify our performance analysis. These results also demonstrate the potential of introducing RIS for improving the secrecy performance of wireless communication systems.
