Physical layer security (PLS) in the presence of multiple eavesdroppers over Nakagami-m fading channels for cooperative decode-and-forward (DF) relay network that consists of one source, one destination, and multiple relays is investigated. Different from the recent PLS system model that only considers one eavesdropper during eavesdropping attack, this paper extends the one-eavesdropper case to a multiple-eavesdropper scenario and investigates joint relay and eavesdropper selection (JRES) strategy against eavesdropping attack over Nakagami-m fading channels. In the proposed strategy, the best relay is selected via the maximum relay forward channel capacity. In addition, since eavesdroppers are noncooperative, the worst case is considered. Namely, the wiretap channel between the best relay and the chosen eavesdropper has the maximum capacity. Traditional direct transmission and opportunistic relay selection (ORS) scheme in the presence of one eavesdropper over Rayleigh channel are regarded as benchmarks. Moreover, a security-reliability tradeoff (SRT) performance is analyzed, where the reliability performance is expressed by outage probability (OP), while the security performance is measured by intercept probability (IP). Closed-form expressions of OP and IP are derived. The numerical results show that the proposed JRES scheme outperforms the traditional direct transmission and the ORS scheme in the presence of one eavesdropper over Rayleigh channel. The SRT performance is enhanced obviously with the increasing of relay numbers and Nakagami channel fading factor m for a given number of eavesdroppers, which extends the PLS and SRT performance analysis to a more general case in a cooperative DF relay network.INDEX TERMS Decode-and-forward (DF) relay network, joint relay and eavesdropper selection (JRES), Nakagami-m fading channels, physical layer security (PLS), security-reliability tradeoff (SRT).

“…Therefore, Zou, Zhu, and Ding investigated the security-reliability trade-offs (SRT) for the cooperative wireless network. [26][27][28][29][30][31] Huang et al 32 studied the SRT in the CRN, and the influence of the primary user on the secondary user was investigated. The authors analyzed SRT performance in two modes of transmission: single-relay selection transmission and multi-relay selection transmission.…”

SUMMARY Increasing the transmitting power will improve the system performance, but it will also increase the potential intercepted risk. Thus, the research of security‐reliability trade‐off (SRT) is valuable. In this paper, we investigate the physical layer security in cognitive radio network (CRN), which consists of a source node, a destination node, an eavesdropper, and multiple relays. The security and reliability are measured by intercept probability (IP) and outage probability (OP), respectively. Different from the previous researches, a more actual scenario is studied for the CRN in the Rayleigh fading environment; that is, the eavesdropper can eavesdrop on the secondary source (SS) and the relays. Besides, we consider the probability of false alarm and missing alarm and study their impact on the OP and IP for direct transmission (DT) and relay selective transmission (RST). The closed‐form expressions of OP and IP show that the false alarm affects the OP and the missing alarm has influence on the OP and IP. Furthermore, we accumulate the sum of the OPs for the RST in the two time slots and compare them with the DT, when we explore the OP. In addition, since the signals may be both intercepted in the two stages of RST, we analyze the IPs in the two time slots respectively and compare them with the DT separately. The simulation results show that the RST scheme can greatly improve the security and reliability by increasing the number of relays compared with the DT scheme.
