“…Later, a more preferable alternative namely SEC with post-examining selection (SECps) was designed to achieve a better secrecy performance in multiuser downlink wiretap networks [26], [27]. In [28], the physical layer security with TAS and threshold-based selection diversity (tSD) scheme was investigated in multiuser multi-antenna wireless networks. The key difference between SEC and SECps scheduling schemes is that SEC scheme selects any branch randomly when no acceptable one is found after examining all the legitimate links, whereas the best branch is selected in the SECps scheme, which guarantees the secrecy performance particularly for the case when the switching threshold is a high value.…”

Abstract-In this paper, we investigate the secrecy performance of multiuser dual-hop relay networks where a base station (BS) communicates with multiple legitimate users via the assistance of a trustful regenerative relay in the presence of multiple eavesdroppers. Particularly, the maximal ratio transmission (MRT) scheme is exploited at the BS and a threshold-based multiuser scheduling scheme is employed over the legitimate users, while concerning the imperfect decoding at the regenerative relay. To evaluate the secrecy performance of the considered system, two practical situations are addressed based on the availability of eavesdropper's channel state information (CSI), i.e., Scenario I, where the eavesdropper's CSI is not available at the relay, and Scenario II, where the eavesdropper's CSI is available at the relay. For both scenarios, we further consider two eavesdropping modes, i.e., colluding eavesdropping and non-colluding eavesdropping. For Scenario I, new exact and asymptotic closed-form expressions of the secrecy outage probability (SOP) are derived. For Scenario II, we derive new exact and asymptotic closedform expressions of ergodic secrecy rate (ESR). The asymptotic SOPs demonstrate that the secrecy diversity order is independent of the number of legitimate users NB and eavesdroppers NE, the number of antennas equipped at eavesdroppers AE as well as fading factor of the wiretap channel mE. Furthermore, we also determine the secrecy multiplexing gain and the power cost to explicitly quantify the impact of the legitimate channel and wiretap channel on ergodic secrecy rate. Our findings demonstrate that increasing the switching threshold, the number of antennas at the BS, and the number of legitimate users have a positive impact on secrecy performance.Index Terms-Physical layer security, cooperative relay, multiuser diversity, threshold-based scheduling scheme, secrecy outage probability, ergodic secrecy rate.

“…Multiuser diversity can improve PHY security [4] [5]. The impact of interference on the PHY security for multiuser diversity schemes is investigated in [6] where the authors analyze the SOP and secrecy diversity order of multiuser diversity scheduling in the presence of cochannel interference, but no closed form expression was derived for the SOP.…”

We investigate the secrecy performance of a multiuser diversity scheme for an interference-limited wireless network with a base-station (BS), N legitimate users and an eavesdropper, in the presence of a single dominant interferer. Assuming interference dominates noise power at the eavesdropper and at each legitimate user's receiver, the BS transmits information to the legitimate user with the k-th best (highest) signal-tointerference ratio. We derive a closed-form expression for the secrecy outage probability for an arbitrary N and an asymptotic expression for a fixed k and large N . Furthermore, we derive a closed form asymptotic expression for the ergodic secrecy capacity of the k-th best user and show that it scales like O (log(N )) for a fixed k and large N .1 The single dominant interferer assumption has been widely considered in the literature, see [12], [13] and references therein. The interfering BS here can be viewed as a co-channel interferer serving another cell (network) that causes an interference to the cell of interest.

“…In addition, Zhang et al and Huang et al investigated the impact of outdated CSI on the secrecy performance of cognitive MIMO wiretap networks assuming different antenna settings, and it was shown that full secrecy diversity gain cannot be achieved under the imperfect CSI condition. Finally, in the works of Yang et al, assuming a cooperative and a noncooperative relay network, respectively, multiuser scheduling in multiantenna wireless networks was investigated assuming perfect CSI. Note that these previous works considered that the eavesdropper does not suffer from jamming signals so that the effect of cooperative jamming plus noise in MIMO wiretap channels with imperfect CSI remains to be investigated in the literature.…”

In this paper, we investigate the secrecy performance of multiple-inputmultiple-output wiretap channels with outdated channel state information (CSI) at the transmitter. The joint effect of multiple jamming signals and noise at the eavesdropper is studied assuming that the transmitter adopts a transmit antenna selection technique, while both the legitimate receiver and the eavesdropper use a maximal-ratio combining scheme to achieve spatial diversity in reception. Exact closed-form expressions for the nonzero secrecy rate probability and the secrecy outage probability for an arbitrary number of power distributed jamming signals are derived, by assuming both perfect and imperfect CSI. The general secrecy outage probability expressions are simplified for 2 special cases, ie, different and equal power distributed interferers. Furthermore, we conduct an asymptotic secrecy outage analysis at high signal-to-noise ratio, which reveals that the expected diversity gain cannot be realized for imperfect CSI and full diversity order can only be achieved under the perfect CSI condition. In addition, our results reveal that the number of antennas at the eavesdropper as well as the number of jamming signals do not affect the system diversity order. Simulation results are performed to illustrate the effects of imperfect feedback and other key system parameters on the secrecy performance. Finally, our analytical results are validated through Monte Carlo simulations.
