“…Later, Chen and others expanded their previous security works to cognitive relaying networks [15,16]. The relay design in previous works [15,16] exploits the maximum ratio combining/zero forcing beamforming scheme to guarantee the secrecy performance of dual-hop short-packet communications. In the underlay cognitive relaying network of Ho and others [17], secondary-source and secondary-energy-harvesting relays send short packets to a secondary destination under interference constraints.…”

We propose short packet communication in an underlay cognitive radio network assisted by an intelligent reflecting surface (IRS) composed of multiple reconfigurable reflectors. This scheme, called the IRS protocol, operates in only one time slot (TS) using the IRS. The IRS adjusts its phases to give zero received cumulative phase at the secondary destination, thereby enhancing the end‐to‐end signal‐to‐noise ratio. The transmitting power of the secondary source is optimized to simultaneously satisfy the multi‐interference constraints, hardware limitations, and performance improvement. Simulation and analysis results of the average block error rates (BLERs) show that the performance can be enhanced by installing more reconfigurable reflectors, increasing the blocklength, lowering the number of required primary receivers, or sending fewer information bits. Moreover, the proposed IRS protocol always outperforms underlay relaying protocols using two TSs for data transmission, and achieves the best average BLER at identical transmission distances between the secondary source and secondary destination. The theoretical analyses are confirmed by Monte Carlo simulations.

“…Packet replication and interface diversity schemes were employed in [ 14 ] to improve the secure spectral efficiency, where eavesdroppers are randomly distributed according to Poisson point processes. In [ 15 ], the spectrum sensing blocklength and transmission blocklength were jointly optimized to maximize the secrecy throughput. In order to achieve both high spectral efficiency and low communication delay, incorporating short-packet communications with non-orthogonal multiple access (NOMA) networks was investigated in [ 16 , 17 , 18 ].…”

Physical layer security is a promising technique to ensure the confidentiality of short-packet communications, since no additional channel uses are needed. Motivated by the fact of finite coding blocklength in short-packet communications, we attempt to investigate the problem of how many the channel uses utilized for channel training should be allocated to perform secure communications. Based on the finite blocklength information theory, we derive a closed-form expression to approximate the average achievable secrecy throughput. To gain more insights, we also present the asymptotic average secrecy throughput under two special cases, i.e., high signal-to-noise ratio (SNR) and infinite blocklength. Moreover, we determine the optimal channel training length to maximize the average secrecy throughput under the reliability constraint and given blocklength. Numerical results are provided to validate the analysis and demonstrate that the performance gain achieved by the optimal channel training length is remarkable, relative to other benchmark schemes.
