In this work, we analyze the secrecy outage performance of a dual-hop relay system composed of multiple-input-multiple-output radio-frequency (RF) links and a free-space optical (FSO) link while a multiple-antenna eavesdropper wiretaps the confidential information by decoding the received signals from the resource node. The channel state information (CSI) of the RF and FSO links is considered to be outdated. We propose three transmit antenna selection (TAS) schemes to enhance the secrecy performance of the considered systems. The secrecy outage performance with different TAS schemes is analyzed and the effects of misalignment and detection technology on the secrecy outage performance of mixed systems are studied. We derive the closed-form expressions for probability density function (PDF) and cumulative distribution function (CDF) over Málaga channel with imperfect CSI. Then the closed-form expressions for the CDF and PDF of the equivalent signal-to-noise ratio (SNR) at the legitimate receiver over Nakagami-m and Málaga channels are derived. Furthermore, the lower bound of the secrecy outage probability (SOP) with different TAS schemes are derived. Besides, the asymptotic results for SOP are investigated by exploiting the unfolding of Meijer's G-function when the electrical SNR of FSO link approaches infinity. Finally, Monte-Carlo simulation results are presented to testify the correctness of the proposed analysis. The results illustrate that the outdated CSI shows a strong effect on the secrecy outage performance. In addition, increasing the number of antennas at the source cannot significantly enhance the secrecy performance of the considered systems.Manuscript received.Mixed RF-FSO systems, outdated channel state information, physical layer security, secrecy outage probability, transmit antenna selection.

“…In the area of cooperative communications, relay techniques have been studied comprehensively. For example, [3] studied a social relationship to effectively select relay users, [4] proposed a social-aware energy-efficient relay selection mechanism that considers the hidden social ties among mobile users. Also, a relay selection policy based on the buffering ability of relay nodes was presented in [5], and the random distribution of relay nodes by treating the relay deployment as a Poisson point process was investigated in [6].…”

“…For instance, Liu et al [3] proposed a D2D communication load balancing algorithm where the D2D device uses D2D relay node to deliver its messages to eNB in case of congested cells. In addition, Zhang et al [4] proposed a social-based D2D relay selection model. The link reliability is assessed via users' contact histories and channel status to improve the success rate of relay selection.…”
