“…Secrecy capacity, which evaluates the effectiveness of secure transmission, has been defined as the maximum rate in each reliable and secure transmission [5]. This metric has been adopted in the security analysis and optimization of 5G mmWave small cell networks [6], co-operative non-orthogonal multiple access with proactive jamming [7], artificial noise (AN)-aided multi-input multi-output (MIMO) Rician channels [8] and so on. As the secrecy capacity may be less than target secrecy redundancy rate, the secrecy outage probability (SOP) has been applied to present a more comprehensive performance evaluation.…”

In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency. First, we analyzed some critical performance metrics, including connection outage probability (COP), secrecy outage probability (SOP) and effective secrecy throughput (EST). Then, to maximize the EST, three optimization problems of rate adaption were discussed: (i) optimizing the code rate with a given secrecy redundancy rate by a parameterized closed-form solution; (ii) optimizing the secrecy redundancy rate with a given code rate by a fixed-point method; (iii) optimizing both code rate and secrecy redundancy rate by an iterative optimization algorithm. We also considered COP and SOP constraints among the problems while corresponding solutions were deduced. Finally, numerical and simulated results verified our conclusions that the approximated SOP matches well with Monte–Carlo simulation for a strict reliable constraint, and that the optimized transmitting rate enhances EST efficiently with multiple eavesdroppers and retransmissions. Moreover, the influence of the number of eavesdroppers on secrecy performance was analyzed. Briefly, secrecy performance inevitably deteriorates with increasing number of eavesdroppers due to raised information leakage.

“…The dominant feature of PLS is to exploit the characteristic of wireless channels to ensure reliable communication links. Recently, the emerging requirement for secure communication has led to a sizable volume of research on PLS techniques, which focus on the study of the secure performance of WCNs over various fading channels; see e. g., [6,[8][9][10][11][12]. In [8], the authors investigated the secrecy outage performance of multiple-input multiple-output (MIMO) systems over Rayleigh fading channels, where a transmitbeamforming scheme was proposed to maximize the signal-to-noise ratio (SNR) of the main receiver.…”

In this paper, we investigate the secure performance of multi-antenna decode-and-forward (DF) relaying networks where the Nakagami-m fading channel is taken into account. In practice, the joint impact of residual transceiver hardware impairments (HIs) and channel estimation errors (CEEs) on the outage probability and intercept probability is taken into account. Considering HIs and CEEs, an optimal transmit antenna selection (OTAS) scheme is proposed to enhance the secure performance and then a collaborative eavesdropping scheme is proposed. Additionally, we present main channel capacity and intercept capacity of the multi-antenna DF relaying networks. More specifically, we derive exact closed-form expressions for the outage and intercept probabilities. To obtain useful insights into implications of parameters on the secure performance, the asymptotic behaviors for the outage probability are examined in the high signal-to-noise ratio (SNR) regime and the diversity orders are obtained and discussed. Simulation results confirm the analytical derivations and demonstrate that: 1) As the power distribution coefficient increases, OP decreases, while IP increases; 2) There exist error floors for the outage probability at high SNRs, which is determined by CEEs; 3) The secure performance can be improved by increasing the number of source antennas and artificial noise quantization coefficient, while as the number of eavesdropping increases, the security performance of the system is reduced; 4) There is a trade-off between the outage probability and intercept probability. secrecy outage probability (SOP) and strictly positive secrecy capacity (SPSC). Regarding the non-homogeneous fading environments, the authors in [11] explored the secrecy performance of Wyner's model over α − µ fading channels. With the help of moment matching method, the authors in [12] derived approximate expressions for the SOP and SPSC over κ − µ shadowed fading channels. On a parallel avenue, cooperative relaying is another promising technique to further improve the spectral efficiency and enhance the coverage of wireless networks [13-15], and thus it attracts plenty of researchers to investigate the security issues of cooperative networks [16-23]. In [16], the authors analyzed the secrecy performance of amplify-and-forward (AF) relay systems over generalized-K fading channels, where three metrics for the SOP, average secrecy capacity (ASC) and SPSC were analyzed. To improve the PLS against eavesdropping attacks, the optimal relay selection (ORS) scheme was proposed for AF and decode-and-forward (DF) relay networks and the intercept probability (IP) for the proposed scheme was derived in closed-form [17]. From the perspective of energy harvesting, the authors in [18] proposed a cooperative transmission scheme for the AF and DF relay networks under the condition of an eavesdropper, where the relays can harvest energy from radio-frequency (RF) signals of a source through power-splitting protocol. In the existing research results, the researchers discuss...

“…However, the wireless channel in some application scenarios is static or quasi-static, and the key generated with such methods is not suitable for encryption, because the key entropy or the key generation rate is too low. To improve the security performance, diversity technology based on multi-antenna system and relay system has attracted more and more attention [ 16 , 17 , 18 , 19 , 20 ]. However, a device in a low-cost wireless network, e.g., the sensor node in WSN (Wireless Sensor Network), is usually equipped with only one antenna.…”

“…Furthermore, Atallah et al [ 32 ] proposed different protocols to foil the eavesdropper. Most of the recently proposed AN schemes are based on a hypothesis that the number of transmit antennas is larger than that of the receive antennas [ 20 ]. This strategy might fail when both legitimate parties are equipped with single antennas in some scenarios.…”

For secure transmission of low cost single antenna communication nodes in wireless crowdsensing networks under static channel, a physical layer communication scheme is proposed, where each digital modulated symbol is encrypted by a random key at the transmitter and decrypted with the same key at the receiver. The legal users exploit the synchronized chaotic sequence and the two-stage block interleaver to generate a complex random variable (random key), whereby its envelope obeys the Rayleigh distribution and its phase obeys the uniformly distribution. The modulated symbol is multiplied by the complex random variable (encryption) to imitate the Rayleigh fading of the channel at the transmitting end. The received symbol is divided by the identical complex random variable (decryption) to recover the transmitted message before the digital demodulation at the receiving end. Simulation results show that the bit error ratio (BER) performance of the legitimate users is consistent with the theoretical value of the Rayleigh fading channel, while the corresponding BER of the eavesdropper is too high (about 0.5) to intercept any information.
