N2 - In this paper, we consider the physical layer security of cooperative multiple relays networks, where the source tries to communicate the destination via modify-and-forward (MF) relaying in the presence of eavesdropper. More practical, transceiver residual hardware impairments (TRHIs) and channel estimation errors (CEEs) are taken into account. To improve secure performance and energy efficiency, the K−th best relay is selected since the best relay is not available due to some schedule and/or other reasons. More specifically, we investigate the reliability and security by invoking the outage probability(OP) and intercept probability(IP). To obtain more useful insights, the asymptotic behaviors for the OP are examined in the high signal-to-noise ratio (SNR) regime, followed by the diversity orders. The numeric results show that: (1) The secure performance is improved by employing MF compared with decode-and-forward (DF); (2) The reliability increases as the total number of relays increases; (3) There is an error floor for the outage probability due to the CEEs.
