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: $\left(1\right)$ The secure performance is improved by employing MF compared with decode-and-forward (DF); $\left(2\right)$ The reliability increases as the total number of relays increases; $\left(3\right)$ There is an error floor for the outage probability due to the CEEs.

在本文中，我们考虑了协作式多个中继网络的物理层安全性，其中源试图在存在窃听者的情况下通过修改转发（MF）中继来与目标进行通信。更实际的是，考虑了收发器残余硬件减损（TRHI）和信道估计错误（CEE）。为了提高安全性能和能源效率，$ķ-ŤH$由于某些时间表和/或其他原因，无法使用最佳中继，因此选择了最佳中继。更具体地说，我们通过调用中断概率（OP）和拦截概率（IP）来研究可靠性和安全性。为了获得更多有用的见解，在高信噪比（SNR）方案中检查OP的渐近行为，然后检查分集阶数。数值结果表明：$（\mathrm{1个}）$ 与解码和转发（DF）相比，采用MF可以提高安全性能。 $（\mathrm{2个}）$ 可靠性随着继电器总数的增加而增加； $（3）$ 由于CEE而造成的中断概率存在错误底限。
